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.
