    A-I Selection Guide to NSKLinear GuidesA-I-1 Structure of NSK Linear Guides By avoiding structural complexity, and by reducing the number of components, we not only enhanced theprecision of linear guides, but also are able to keep costs low. We have added NSK's patented unique structuralfeature to the original invention (Fig. I-1-1). This contributes to higher precision and lower prices.NSK linear guide consists of a rail and a ball slide (Fig. I-1.2). The balls roll on the grooves on the rail and theball slide, and scooped up by the end caps attached to both ends of the ball slide. Then, the balls go through theopening made in the ball slide, and circulate back to the other end.

    A-I-2 Characteristics of NSK Linear GuidesThe use of a unique offset gothic arch groove (Fig. I-13) allows the NSK linear guides to satisfy groove designsrequired for specific purposes.The precise measurement of the ball groove leads to stable production of highly accurate linear guides andinterchangeable linear guides. (Fig. I-14).Such technologies eusure the feature of NSK linear guides outlined below.

    (1) Abundant in type for any purpose* Various series are available, and their ball slide models and size categories are standardized to satisfy any

    requirement. Our technology, polished by abundant experience in the use of special materials and surfacetreatments, meets the customers most demanding expectations.

    (2) High precision and quality* High precision and quality come from our superb production and measuring technologies, strengthened by

    extensive experience in antifriction rotary bearings and ball screw production. Our quality assurance extends tothe smallest components.

    (3) High reliability and durability* Logical simplicity in shape, along with stable processing, maintains high precision and reliability.* Super-clean materials, our advanced heat treatment and processing technologies increase product durability.

    (4) Component compatibility shortens delivery time* Interchangeable parts: The adoption of the gothic-arch groove which makes measuring easy, and a new

    reliable quality control method has made random-matching of the rails and the ball slides possible. The partsare stocked as standard products, thereby reducing delivery time.

    (5) Patented static load carrying capacity (shock-resistance)* When a super-high load (impact) is applied, our gothic-arch groove spreads the load to surfaces which usually

    do not come into contact. This increases shock resistance (Fig. I-15).

    A The DF contact structure greatly absorbs theerror in the perpendicular direction to rail at thetime of installation.

    A Balls make contacts at two points thanks to theoffset gothic-arch groove. This keeps friction toa minimum.

    A Structural resistance against shock load.A Gothic-arch groove renders measuring of ball

    grooves accurate and easy.A Standardized interchangeable assemblies

    allows separate purchase of rails and ballslides.

    A-I-2.1 Types and Characteristics of NSKLinear Guides

    We have abundant types of linear guide for anypurpose to accommodate the most special needs ofthe users.

    (1) Types of series and classification byfeature

    A There are two types of NSK linear guide: 1. Rigidity and load carrying capacity against the

    vertical direction are greater than the rigidityand load carrying capacity against the load fromthe lateral direction (high vertical load carryingcapacity type);

    2. Load is equally distributed to four directions (four-directional iso-load carrying capacity type)

    A There are three types of NSK linear guide by thelength of the ball slide 1. Standard length ball slide with high-load

    carrying capacity;

    2. Long ball slide with super-high load carryingcapacity;

    3. Short ball slide for mid-level load carryingcapacity.

    A Four-row ball grooves linear guide has two types: 1. Self-aligning capability- which absorbs certain

    amount of installation error;2. High moment carrying type with great moment

    rigidity. A Two-row ball grooves linear guide has mid-level

    moment rigidity.A Interchangeable parts: Thanks to the ease of

    measuring gothic-arch groove, we can preciselymanufacture rails and ball slides, and thus, youcan purchase the rails and the ball slidesindividually and assemble them randomly.

    A Stainless steel is also available as standardmaterial for some series.

    A The contact angle between the ball and the

    raceway is set at 45 degrees. This makes load

    carrying capacity and rigidity equal in vertical

    and lateral directions.

    A Six-row ball grooves support load from

    vertical and lateral directions, enhancing

    rigidity and increasing load carrying capacity.

    A The contact angle between the ball and the raceway is set

    at 45 degrees. Therefore, load carrying capacity and

    rigidity are equal in vertical and lateral directions.

    A Balls contact at four points during high preload. The four-

    row ball groove supports the load from vertical and lateral

    directions. This makes the linear guide highly rigid.

    A Rigidity against moment load is great due to the DB

    contact (at time of light preload) or the four-point contact

    (at time of high preload)

    A Sliding resistance slightly increases, absorbing vibration to

    the rail longitudinal direction due to the four-point contact

    at time of high preload.

    A Ideal for heavy cutting machine tools.

    A Strong against shock load

    A The contact angle between the ball and the raceway is setat 50 degrees. The load carrying capacity against verticaldirections, which is prevalent in most operations, increaseswith this design

    A The rail is wide. This contributes to a high rolling moment

    carrying capacity and to great moment rigidity when only

    single linear guide is in use

    A Balls contact at two points in the offset gothic arch groove,

    keeping friction small.

    A High resistance against shock load

    A Standardized interchangeable assemblies allows separate

    purchase of rails and ball slides.

    A Extremely thin, and wide in shape. This is ideal in use ofonly single linear guide.

    A-I-3.2 Selection of Linear Guide Size (Model number)

    To select a linear guide of satisfactory durability; it isa standard practice to calculate its expected life. Priorto calculating the linear guide's life expectancy, selectan appropriate size of the linear guide. Below is an easy selection method. After selectingthe size by this method, check the life by using the"A-II-3.2: Calculation of Life Expectancy."

    (1) Select the size based on the space to beused.

    Select a linear guide which matches the space inwhich it is used. Select directly from the "A-I-5:Model Number and Dimension Table."

    (2) Select the size based on the ball screwsize.

    Always select a linear guide which matches the sizeof the screw shaft diameter, or the size closest to it,e.g., when the ball screw shaft diameter is 32, selectlinear guide type LH30, or LH35.

    (3) Select the size based on the estimatedload on one ball slider.

    Most linear guides are table-shaped and have tworails and four ball slides for an axis.Assuming the linear guide is this type, calculate arough load per ball slide using the formula below:

    (3.1)

    P : Load per ball slide

    Kp : Load position coefficient

    F : LoadLoad position coefficient Kp should be found for eachload by the proportion of the distance between ballslide span and load point, and the distance betweenrail span and load point.

    (A) When load is vertical(Fig. I-31)

    (B) When the load is in the axial direction(Fig. I-32)

    (C) When the load is lateral to the rail(Fig. I-33)

    The load position is normally the coordinate position.Disregard + or - symbols, and use absolute values.

    Upon obtaining the load value P per ball slide byusing the above position coefficient Kp in (3.1), selectthe matching size (model number) from Fig. I-34.Because the above calculation formula is a simpleone, the load obtained by the above formula may belarger than the actual case if the value of Kp is over 1,or in the case three patterns (A), (B), and (C) arecombined. In such case, the size to be selected (model number) should be larger; however, the lifewill be longer.

    A-I-3.4 Accuracy and Preload

    (1) Accuracy grades and types of preload

    1 Accuracy grades The accuracy grade which matches the

    characteristic of each series is set for NSK linearguides.

    Table I-31 shows accuracy grade set for eachseries.

    See Page A153 for accuracy specifications of each

    series. Refer to "(2) Application examples of accuracy

    grades and preload" which shows cases ofappropriate accuracy grade and preload type forspecific purpose.

    A21

    A-I-3.3 Example of Linear Guide Selection (Model number)

    The selection below used "A-I-3.2 (3) Selectionbased on load per ball slide."In this example, let us select a linear guide for asingle axis table as illustrated below.Use LH-AN type in LH Series which is selected basedon "A-I-2.1 Types and Characteristics of NSK LinearGuides."

    Weight and coordinates of Table W :500N, ( 0, 0, )

    Weight and coordinates of Weight F1:2500N, ( 100, 120, )

    Weight and coordinates of Weight F2:1000N, ( 0, 180, )

    Since the above is all vertical load, we do notconsider Z axis coordinates.Therefore, the formula "(A) When vertical load isapplied" is.:

    A-I-5.1 LH Series

    (1) High self-aligning capability (rolling direction) Same as the DF combination in angular contact bearings,

    self-aligning capability is high because the cross point of

    the contact lines of balls and grooves comes inside,

    reducing moment rigidity.

    This increases the capacity to absorb the error of

    installation.(2) High load carrying capacity to vertical

    directionThe contact angle is set at 50 degrees, increasing load

    carrying capacity as well as rigidity in vertical direction.(3) High resistance against impact load

    The bottom ball groove is formed in gothic-arch and the

    center of the top and bottom grooves are offset as shown

    in Fig.I-52. The vertical load is generally carried by the

    top rows, at where balls are contacting at two points.

    Because of this design, the bottom rows will carry load

    when a large impact load is applied vertically as shown in

    Fig.I-53. This assures high resistance to the impact load.(4) Highly accurate as shown in Fig. I-5.4, fixing the master rollers is easy thanks to the

    gothic-arch groove. This makes easy and accurate

    measuring of ball grooves. (5) Easy to handle, and designed with safety in

    mind.Balls are retained in the retainer, therefore they do not

    fall out when the ball slider is withdrawn from the rail.(6) Abundant models and sizes

    Each series has various models of ball slides, rendering

    the linear guide available for numerous uses.(7) Interchangeable series is available (prompt

    delivery) The series enables random matching of rails and ball

    slides (interchangeability) for prompt delivery.

    (1) High self aligning capability (rolling direction)Same as the DF combination in angular contact bearings,self-aligning capability is high because the cross point ofthe contact lines of balls and grooves comes inside,reducing moment rigidity. This increases the capacity toabsorb the error of installation.

    (2) High load carrying capacity to verticaldirection

    The contact angle is set at 50 degrees, increasing loadcarrying capacity as well as rigidity against the load invertical direction.

    (3) High resistance against impact loadThe bottom ball groove is formed in gothic-arch and thecenter of the top and bottom grooves are offset as shownin Fig. I-56. The vertical load is usually carried by top 2rows at where balls are contacting at two points. Becauseof this design, the bottom rows will carry the load when alarge impact load is applied as shown in Fig. I-57. Thisassures high resistance to the impact load.

    (4) Highly accurateAs shown in Fig. I-58, fixing the measuring rollers issimple thanks to the gothic-arch groove. This makes easyand accurate measuring of ball- grooves.

    (5) Easy to handle, and designed with safety inmind.

    Balls are retained in the retainer and do not fall out whenthe ball slide is withdrawn from the rail.

    (6) Abundant models and sizes come in series.Each series have several ball slide models, rendering thelinear guide available for numerous uses. The LS Seriesalso has standardized long stainless- steel rail (maximum:3 500 mm).

    (7) Interchangeable series is available (shortdelivery time)

    The series enables random matching of rails and ball

    slides (interchangeability) for prompt delivery.
