The drylin® R shaft guide – dimensions identical to those of recirculating ball bearings
drylin® R linear bearings 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.

drylin® R shaft guide design
Floating bearing for shaft guides
The drylin® R floating bearings offer great advantages in applications with parallel shafts. With their geometry, they are able to compensate for alignment and parallelism errors and should be used on the shaft located furthest from the drive mechanism.For the design tip
Sustainability
drylin® linear technology does not use a single drop of lubricating oil. In addition, our tribologically optimised materials produce less micro-abrasion than commercially available plastics. Longer service life also has a positive net effect on the environment.
