Spherical plain bearings and rod ends for motorsport are basically the same as those for industry. However, industrial bearings are not suitable for motorsport. The requirements for the bearings are different from those for mechanical engineering. Very important are the high demands on function and load capacity. For this reason, we have developed the motorsport series. These are specially designed for the high loads and speeds in motor sports and offer optimum performance.


Our motorsport rod ends and spherical plain bearings are available in different series, in metric dimensions or in inch dimensions, dimensional series K or E, maintenance-free with PTFE sliding film, maintenance-required, with V-groove or without, for rod ends as internal or external thread, right-hand, left-hand or fine thread. The bearing clearance is always reduced for motor sport bearings. We develop special designs or customised bearings based on your requirements.


Spherical plain bearings and rod ends are a special form of plain bearings and are subject to the DIN ISO 12240-1 and 12240-4 standards. Within the standards, the dimensional series, tolerances, radial internal clearance and dimensions are specified. The standards are very broadly defined, so that a large number of sliding pairings, materials, surface treatments etc. are possible. The designations, the load ratings as well as the service life calculations are not subject to the standard and thus differ from manufacturer to manufacturer. Depending on the series, the spherical plain bearings and rod ends of the motorsport series are partly completely within the standard or are manufactured based on the standard.

Areas of application

The name says it all. The field of application is motorsport in all its facets, from go-karts to motorbikes to racing cars in rallye and formula sport. Our bearings are used in chassis, shock absorbers, steering linkages and in the suspension and drive train.

Technical basics motorsport parts

The technical principles of our spherical plain bearings and rod ends can basically be transferred to the motorsport version. However, the tolerances are tighter and the bearing clearance is reduced to achieve higher precision and load capacity.


Our motorsport series comprise various series that are specially adapted to the requirements of motorsport. These include the high-performance series for extreme loads, the Formula Student series for use in student racing projects and the V-groove series for special applications.




The V-groove series is a special series for applications that require high precision and load capacity. The V-groove enables optimum power transmission and ensures a long bearing life.


High-Performance Liner

Our high-performance liners are specially designed for use under extreme conditions. They offer high temperature resistance and excellent chemical resistance, making them ideal for use in motorsport.
