drylin® R linear shaft guides

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.


  • Self-lubricating – no external lubrication required
  • Dimensionally identical to standard recirculating ball bearings
  • Corrosion resistant (with hard-anodized and 300-series components available)
  • Dirt resistant, lightweight, for all shaft materials
  • Easily-replaceable plastic bearing liners keep installation time to a minimum
  • Various plastic bearing liner materials available for additional technical advantages
  • Various housing options available
  • Aluminum, steel, stainless steel and carbon fiber shafts 
  • Up to 250°C (482°F) long-term (depending on materials)
Industries:  Packaging machinery, Laboratory equipment, Kiosks/vending, 3D printing

drylin® R linear shaft design

Floating bearing for shaft

drylin® 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.

Learn more about our linear shaft bearing design in our Tech-Talk entitled "The 2:1 Rule and Defining Fixed/Floating Bearings".
