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 shaft bearings guarantee toughness and precision – even under extreme environmental conditions.
Tech up, cost down: we will always give you at least one of the two. That is our profession and what we have offered for many years. The challenges of the "upside-down" year of 2021 have spurred us on to improve our efforts. Experience the drylin® innovations of 2021.
Thanks to dimensions identical with commercially available shaft guides with recirculating ball bearing systems
Can also be deployed in the food industry and the pharmaceutical industry as hygiene is provided
Thanks to adjustable bearing clearance at the sliding elements
Thanks to absorbing forces from all directions
Low vibration and quiet movement
Thanks to lubrication-free sliding elements that push away the dirt on the running surfaces of the shafts
The drylin® R quad block is offered in open or closed design. In the open version, the linear carriage can be used for supported linear shafts.
Find the suitable plain bearing liner for your application need. Whether for high speed or temperatures from -50°C to +250°C or with FDA/EU conformity. igus® offers the ideal material for your drylin® R application.

You can use the drylin® linear guides expert to quickly and easily configure an individual linear guide for your application in just five steps.
The drylin® R shaft guide is based on especially developed highly wear-resistant polymers. The dimensions are compatible with standard ball bearings. The special shape permits their use even in extreme environments.
drylin® R linear plain bearings are used in the bus trailers manufactured by Göppel Bus GmbH. They transfer the steering movement from the front to the rear wheels.
This laboratory press is in no way an off-the-shelf product but a customised solution. Tough stainless steel shafts and temperature-resistant and lubrication-free polymer bearings ensure a high level of availability of the heart of the machine. The materials deployed here from the drylin® R product range easily withstand the extreme conditions.
This apparatus can be used to measure the adsorption heat of small organic molecules (e.g. isopropanol) in single crystals (e.g. platinum). In order to guarantee that measurements are exact as possible, the precise components used in the apparatus are also able to withstand high temperatures of up to 180 °C.
drylin® R aluminium shafts are used in this grinder to guide the cutting table. The linear plain bearings on the basis of high-performance polymers operate completely without lubricants. This makes the shaft guide resistant to dirt accumulations while providing smooth operation.
This saw cuts plastic films wound on spools. The saw blade can be moved over the entire length of the spools and saw into the film. The movements of these two axes are guided by supported shafts and shaft guides from the drylin® R range. Precise positioning for clean cuts and a fully maintenance-free plant were of importance here.

The drylin® R floating bearings offer great advantages in applications with parallel shafts. With their geometry, they are able to compensate for alignment and parallelism errors and should be used on the shaft located furthest from the drive mechanism.
Our drylin® products are tested in a test laboratory under a variety of conditions to ensure that they function reliably even in tough environments. Here we show you what is tested and how, and what happens to our test data. You can even have your application tested at igus®.
