drylin R shaft guide - the maintenance-free solution
Guarantee robustness and precision
drylin R shaft guides are based on highly wear-resistant polymers developed especially for linear technology. The dimensions are compatible with standard ball bearings. The special shape of the shaft guides and shaft bearings guarantee toughness and precision - even under extreme environmental conditions.

Why choose drylin R shaft guides?
One to one replacement very easy
Dimensions are identical to those of standard shaft guides with recirculating ball bearings
FDA compliance with stainless steel
Can also be used in the food and pharmaceutical industries thanks to special hygiene features
High precision
Adjustable bearing clearance at the sliding elements
Tough and flexible
Force absorption from all directions
Quiet operation
Low-vibration and quiet movement
Lubrication-free sliding elements push away dirt on the running surfaces of the shafts
The components of the drylin R shaft guide
Wooden shafts study
Wear on wood
We have carried out various tests on the coefficient of friction and the wear rate of our materials. Plain bearings and liners made of the materials iglidur J and J4 were tested on various wooden shafts in comparison to metal shafts.

Floating bearings for shaft guides
The drylin R floating bearings offer great advantages in applications with parallel shafts. Due to their geometry, they are able to compensate for misalignment and parallelism errors and should be used on the shaft furthest from the drive mechanism.
