Selected application examples
drylin® R in commercial vehicle technology
Tough & maintenance-free
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.

drylin® R in laboratories
Stainless steel shafts with fixed flange bearings and plain bearing for laboratory press
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.

drylin® R in an ultra-high vacuum apparatus
In use in research for precise measured values
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 in parting-off grinder
Aluminium shaft and plastic bearings for precise linear guidance
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.
drylin® R shaft guide in film saw
Precise positioning for clean cuts
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.
drylin® R shaft guide design
Floating bearing for shaft guides
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.For the design tip
