ISO dimensions• Overall dimensions of MB bearings are in accordance with ISO 3228 standards • All MB bearings are interchangeable with their correspondent cast iron versions

• MB bearings are equipped with stainless steel AISI 304/316 bushes to reinforce mounting holes • The reinforcing bushings avoid damages to the plastic flange during screw tightening

Fixing bushes

• Only best quality glass fibre reinforced polyamide PA FV / polypropylene PP FV thermoplastic resins are used for the MB housings• The resins used guarantee high resistance to oxidation and corrosion and at the same time equal the strength offered by cast iron housings. They offer a better resistance to impact • Polyamide PA FV resins offer maximum heat and mechanical resistance • Polypropylene PP FV resins offer maximum resistance to chemical agents

Thermoplastic resins

• A system of waterproof seals protects the bearing from external environment• Protection from dust, humidity, washouts, chemical agents• The clip-on protection cover allows inspection of the bearing

Waterproof housingSeal

O-Ring

• MB bearings are equipped with ball bearings featuring multipurpose sealing systems. • 2 - Superagriseal unit. The system consists of a metallic ring fitted with a low friction rubber sealing lip• 2 F - Superagriseal unit + centrifuging ring. The system is further equipped with a metallic protection ring providing a centrifugal sealing action.• 2 RF - Superagriseal unit + rubberised centrifuging ring. This system is used in stainless steel bearings. The upper lip of the centrifuging ring together with the grease trapped between the base seal and the ring itself guarantees maximum sealing capacity.

Bearing seals

• Waterproof MB bearings feature seals for the protection against external environment• Viton rubber seals ensure maximum resistance to chemical agents

Support seals

• All MB bearings are self-aligning, capable of compensating misalignments up to 2.5°

Bearings with grub screw locking system

Prelubricated with long lasting lithium/calcium grease • Can be rilubricated • Suitable for single directional or bi-directional travel (can reverse the sense of rotation)

Locking of the bearing is achieved by rotating the eccentric collar. The grub screw holds the collar and avoids rotation • Prelubricated with long lasting lithium/calcium grease • Can be rilubricated • Suitable for single directional travel (cannot reverse the sense of rotation) • Higher resistance to vibrations

The bearings have double row of balls running on a spherical outer race This configuration renders the bearing self aligning • The bearings are supplied without sealing units • They are held into position by shoulders on the shaft

Int. dia. bearing

2 - Superagriseal unit. The system consists of a metallic ring fitted with a low friction rubber sealing lip.2 F - Superagriseal unit + centrifuging ring. The system is further equipped with a metallic protection ring providing a centrifugal sealing action.2 RF - Superagriseal unit + rubberised centrifuging ring. This system is used in stainless steel bearings of YAR 2RF/ HW series. The upper lip of the centrifuging ring together with the grease trapped between the base seal and the ring itself guarantees maximum sealing capacity.

The bearing locking systems by grub screws/eccentric collars, allow axial loads up to 20% of the dynamic load coefficient (only with non hardened shafts and grub screws tightened as recommended) • For bearings of the YAT 2, YAR 2F, YAR 2RF/ HV, YET 2 series it is not recommended to exceed the value of : 0,25 • C

The table indicates the values for YAT 2,YAR 2F, YET 2 series bearings • Stainless steel bearings of the YAR 2RF/HV series ( rubberised centrifuging ring) must not be operated at velocities in excess of 60% of the values indicated • The maximum velocity is dependant of the shaft tolerances.

Prelubricated with long lasting lithium/calcium grease • Can be rilubricated • Suitable for single directional or bi-directional travel (can reverse the sense of rotation)

Locking of the bearing is achieved by rotating the eccentric collar. The grub screw holds the collar and avoids rotation • Prelubricated with long lasting lithium/calcium grease • Can be rilubricated • Suitable for single directional travel (cannot reverse the sense of rotation) • Higher resistance to vibrations

The bearings have double row of balls running on a spherical outer race This configuration renders the bearing self aligning • The bearings are supplied without sealing units • They are held into position by shoulders on the shaft

Service life

Expected life calculation formula

FL, F, SF, FC

The service life of a bearing is expressed in the number of revolutions or hours of operations which can be expected without breakdown (erosion or laminations of the bearing revolving parts ).The dimensioning of the bearing requires the knowledge of the appropriate life expectancy of the project in relation to the specific application. This depends on the type of plant, daily /yearly working hours and on the required reliability.In the absence of practical experience Table 1 gives our recommendations of the average expected plant life under various conditions.

Table 1 - Recommended plant expected life L10h for MB support bearings

Bearing dimensioning

Calculation procedures for MB bearings

The bearing dimensions, for a given application, should be chosen on the basis of the loads to be supported, expected service life and reliability. In most cases the reason for choosing a bearing is the fact that the shaft has already been sized during the design of the plant.

Equivalent dynamic load P calculation

Operating conditions coefficients

Correct expected life

Table 2 - Equivalent dynamic load P calculationIf load F acting on the bearing is of constant intensity, direction and is purely radial, it can be inserted in the life formula using P = Fr.In the case of a combined load ( radial + axial ), the load has to be transformed into an equivalent load.The equivalent load will eventually have the same effect as the combined load on the life expectancy.

The calculation procedure for MB bearings consists in ensuring a satisfactory operating life of the unit:

1 ) - The nominal service life is calculated using the formulas indicated below, keeping in mind the type of stress on the bearing. In rolling-contact bearing technology dynamic and static loads are considered separately. - Dynamically stressed bearings Bearings which rotate under a load ( the inner and outer rings of the bearing rotate in relation to each other ). Generally the MB supports are dynamically stressed. - Statically stressed bearings In this case the stressed bearing does not rotate (no rotation of one ring in relation to the other ), or it does rotate very slowly.

2) - The nominal life of the bearing should reflect the expected service life of the plant as indicated in Table 1 hereunder.

Warning• Do not grease at first assembly.

• The first lubrication must be carried out only for bearings of the series FL - F - SF - FC held by the shaft shoulders.

• Stainless steel pressed metal supports of the series SBF are not relubricatable.

• Use only grease of same characteristics as indicated.

• Clean greasing nipple before each greasing operation.

• Inject grease slowly until it comes out from the bearing. Keep the bearing rotating and do not apply excessive pressure which could damage the sealing units.

• More frequent greasing operations with smaller quantities of grease are to be preferred.

All MB bearings are supplied factory lubricated.WarningThe first lubrication must be carried out only for bearings of the series FL - F - SF - FC held by the shaft shoulders.

MB bearings are prelubricated with long lasting lithium/calcium grease.

Relubrication intervals vary according to actual operating conditions. Very often during operation, load, speed, temperature and ambient conditions (humidity, dust ) may vary making it difficult to establish exact rules. Experience once again gives the best answer:

• Light operating conditions :• Normal operating conditions :• Heavy operating conditions :

relubricate every 6 months.relubricate every 1÷ 3 months.relubricate every 2 weeks.

All MB bearing units are equipped with a grease nipple of the ball type to allow periodical relubrication of the bearing.

3 - The table gives the recommended maximum tightening couples for the grub screws and the size of the hexagonal to use.

4 - Tighten the collar by turning it with a punch in the same direction as the rotation of the shaft.5 - Hand tighten the grub screw. The screw driver dimension and the tightening couple are given in the table above (Ref. YET series bearings).

6 - Assembly. The sealing unit of open end covers must be greased to avoid initial dry running on the shaft. The grease must fill only the space in between the two sealing lips.7 - Removal. Insert a screw driver into the groove provided for and force the cover out.

1 - With waterproof bearings the rubber sealing units must be greased before mounting to avoid initial dry running on the shaft. The grease must fill only the space in between the two sealing lips.2 - The bearing must be locked onto the shaft after the support mounting flange has been fully tightened. This is necessary to allow the bearing to assume its correct alignment on the shaft without undue axial stresses. Always tighten the screws diagonally (maximum tightening couple for M10 screw = 50 Nm).
