Linear shafts for smooth & consistent operation: drylin® R
An alternative to recirculating ball bearings
drylin® R linear shafts consist of iglide® plastic liners and anodized aluminum housings that are dimensionally identical to standard recirculating ball bearings. The plastic liner’s patented split design allows for easy assembly onto the linear shaft while the shaft is still in place. Plus, built-in slide pads wipe away debris, making drylin® R linear shafts ideal for use in dirty environments. Choose between multiple iglide® liner materials for high temperatures, FDA-compliance, chemical resistance and other technical advantages. They are available in both metric and imperial sizes.

drylin® R linear shaft design
Floating bearing for shaftdrylin® R linear shaft bearings are self-aligning and offer great advantages in applications with parallel shafts. They can compensate for alignment and parallelism errors and should be used on the shaft located farthest from the drive mechanism.
