drylin® R linear sleeve bearings

drylin® R shafting is available in hard-anodized aluminum (AW 6061/6060), stainless steel (420C, 440B, 304, 316 and hard-chromed), carbon fiber and steel (CF-53). Bearing liners come in J, J200, E7, X, A180 and A160, so you can match the material to your temperature, chemical resistance or FDA-compliance needs.

The max length of drylin® R shafting ranges from 3,000mm – 6,000mm depending on the chosen material and diameter of the shafting.

igus® does provide custom machining of drylin® R shafting. Custom solutions can be configured using our online configurator tool. If your part cannot be configured with the tool, please send us a drawing for internal review and quoting.

Our free online service life calculator helps you select the right system size for your application. It uses thousands of hours of real-world test data from our test lab in Germany, and it gives you the required drive force, safety factors and expected liner life.

drylin® R composite polymer bearings incorporate self-lubricating technology that keep the bearings consistently and adequately lubricated. As a result they are dry-running and require zero external lubrication.

drylin® R shafting is available supported or unsupported. For unsupported shafting, account for shaft deflection. The liners have a patented split design, so they can be assembled onto a shaft that's already in place. Many systems use two shafts, and these need precise alignment to prevent jamming.

igus® provides a number of off-the-shelf pillow blocks as well as universal adapters to fit into prefabricated housings.

drylin® R bearings run dry, so they need no external lubrication and hold up well in dirty and wet environments. Built-in slide pads also wipe away debris. They match the dimensions of standard recirculating ball bearings, so you can retrofit without redesigning, and the liners are easy to replace. That cuts maintenance costs compared with lubricated systems.

drylin® R bearings come with cost-effective, easy-to-install replacement liner in all available materials. These liners have special grooves which lock them within our housings. Split housing options are also available for easier assembly.

Yes. drylin® R bearings are dimensionally interchangeable with standard recirculating ball bearings of the same diameter, in both metric and imperial sizes. Use our 1:1 replacement guide to find your match.

drylin® R is available in two FDA-compliant materials: A180 and A160.

Most drylin® R systems require two rails with precision alignment to prevent jamming. drylin® R rails should be aligned using the following guide: Aligning Rails 101. Additionally, our carriages have an option for floating carriages to help increase clearance between the shaft and liners to help with any misalignment of the rails after installation.

drylin® R is robust, hygienic, and excellent in dirty or wet environments. As a result it is often found in agriculture, packaging, 3D printers, and automation industries.
