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 bearings guarantee toughness and precision – even under extreme environmental conditions.

You can use the drylin® linear guides expert to quickly and easily configure an individual linear guide for your application in just five steps.
drylin® R is the "round" section of the drylin® family. The standard round hollow and solid shafts are found here, alongside a variety of housings and carriages.
drylin® R can be used in a large variety of applications, even extreme environments. You can check the suitability using the configurator tool on our website.
The drylin® R required no lubrication, comes in a huge variety of materials and sizes and are standard off the shelf products.
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.
