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.

Benefits:

  • 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
  • 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
  • For all shaft materials
  • Aluminum, steel, stainless steel and carbon fiber shafts available
  • Temperatures 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".

Application examples

The drylin® R linear shaft bearings are designed with wear-resistant, high-performance plastics and can be used in extreme environments. They’re also dimensionally identical to standard recirculating ball bearings.

drylin® R in a grinder

drylin® R aluminum shafts are used in this grinder to guide the cutting table. The plastic linear bearings operate without any external lubrication, which makes the assembly resistant to dirt and enables smooth operation.

drylin® R in a saw

This saw moves over the entire length of the spools and saws into the film. The drylin® R range was used to guide and support the movements of the two axes, ensuring precise positioning for clean cuts and a fully maintenance-free plant.

drylin® R in systems that produce aluminum parts

The Mall + Herlan GmbH systems can extrude, coat and print many types of cylindrical aluminum parts. drylin® R was used in these systems since they don’t require external lubrication and are resistant to paint mist.

drylin® R in a compaction unit

Recirculating ball bearings that were once used in this compaction unit had to be replaced every 2-3 months. drylin® R linear shaft bearings extended the maintenance rate by two years, despite the dirty environment and abrasive agents.
