DryLin® TR | Linear Screw Drives

Screw drives are machine components that convert a rotary motion into a linear motion. DryLin® screw drives are always based on self-lubricating plastic nuts and thus enable a life-long operation without external lubrication.

Avantages: Dry run, without lubrication Insensitivity to dirt Corrosion-free Low noise Maintenance-free Anti backlash option gives zero clearance operation

Vibration dampening

When not to use them? For required positioning accuracybelow 10 μm

For dynamic high-load applications When an efficiency greater than 50 % is required

The leadscrew (trapezoidal or high-helix thread) remains dry

in operation, and dirt cannot stick to lubricants. This means

that DryLin leadscrew drives can be used in extremely con-

taminated environments as well as in hygienic applications.

Classic format adjustments and lifting applications can be

implemented with the self-braking trapezoidal threads.

Quick adjustments or handling utilize the high ratio of the

high helix thread. All leadscrews are available in steel or

stainless steel and are corrosion free in combination with

DryLin® threaded nuts made of iglidur® plastics.

DryLin® TR leadscrew drives run without maintenance or

lubrication on different screw materials, because the nuts

are made from iglidur® high-performance Tribo-Polymers.

These leadscrew nuts, compared to the nuts requiring

maintenance and lubrication, offer substantial advantages

especially for the application areas in packaging technology

(cleaning) and applications involving high dust formation

(textile machines).

Wet AreaFor applications in humid environments, especially in wet

areas, the trapezoidal leadscrew nuts made of iglidur® J

should be used. The iglidur® J material exhibits very low

moisture absorption. iglidur® J, page 89

Testing of TR Linear Screw DrivesDryLin® TR linear screw drives are manufactured to com-

ply with the DIN 103 standard. The testing takes place by

means of a standard thread gage after production. For

thread sizes that are not listed in the standard table, DIN 103

is converted to the corresponding size. The hygroscopic and

thermal properties of the material are to be considered in the

selection. Dimension changes can occur through moisture

and/or heat in the application. For these reasons, a general

DIN-compliance cannot be guaranteed. The use of plastic

trapezoidal leadscrew nuts for precision drive is therefore

not recommended without testing first. Please contact igus®

technical support to help with the selection of DryLin® lead-

screw drives for your application.

Leadscrew Nuts with FlangeThe DryLin® TR flanged leadscrew nuts are fitted with M6

screws, these should be tightened with a torque up to 2.5 Nm.

It is recommended that the screws are secured by the

use of thread-lock or other means. If a higher torque is

required, then metal sleeves should be pressed into the

mounting holes.

Leadscrew SelectionAs well as the leadscrew nut, the leadscrew itself has an

equal influence on the operation and behaviour of the linear

system. It is recommended that both the leadscrew nut

and the leadscrew are purchased from a single supplier.

Leadscrews are tested with thread gauges corresponding

to DIN 103. The selection of the leadscrew material depends

heavily on the leadscrew nut material. In general, DryLin®

TR leadscrew nuts can be used with steel, stainless steel

or hard anodized alumnium leadscrew nuts.

Trapezoidal Leadscrew Selection The load capacity of the trapezoidal leadscrew nuts made

of high-performance polymers is dependent on the surface

pressure, the surface speed and the resultant temperature.

The temperature behavior is additionally influenced by the

duty cycle as well as the selected leadscrew material and

the specific heat conductivity. The surface pressure of the

DryLin® trapezoidal leadscrew nuts should not exceed

5 MPa long term.
