drylin® R linear shafts systems

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 bearings guarantee toughness and precision – even under extreme environmental conditions.
  • 100 % lubrication-free
  • Large variety of choice in housing shapes
  • Shafts, shaft end blocks and accessories available from stock
  • 8 different shaft materials
  • Replaceable liners
  • Our rails can be joined together to make unlimited lengths, unlike ball bearing systems.

Selected application examples


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.
