Linear shafts system drylin® R

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.
