Detents Pins and Sleeves

Longevity for high-performance operation

ROLLAX components such as ball and spring locking devices, sleeves and detent mechanisms, perform their duty in gearboxes and numerous gearshift assemblies of a number of renowned automotive manufacturers. The products, known under the “RJS” brand name on the open market are designed specifically for high-performance operation and are valued for their longevity and precision. The optimised rolling characteristics and specific spring curve characteristics ensure a rich and precise gearshift feeling. Our solutions, either threaded or press fit, offer unique advantages enabling flexible gearbox design. In addition our portfolio includes ball and spring sleeves for frictionless longitudinal shift rods.

ROLLAX ball and spring locking mechanisms with sensor

A case in point for innovative automotive engineering and the integration of electronic functions is the ball and spring locking mechanism with sensor. It allows the mechanical component to be connected, via a serial interface, to the vehicle on-board-control providing information as to the selected gear.

ROLLAX – precision gearbox components

ROLLAX has established itself as a globally recognised and respected automotive supplier manufacturing, among other things, gearbox components such as ball and spring plungers and detent mechanisms. Designing and testing all of our products in-house we make good use of more than fifty years practical experience in the automotive industry.

The automated systems required in the manufacture of our components are designed, built and tested in-house in our dedicated engineering department. This gives us the means to act on your ideas and suggestions while at the same time respecting the specific gearbox specifications. The highest quality standards in purchasing, design and manufacturing ensure that you receive only the highest quality, thoroughly tested, gearbox components. Additionally, numerous 100% quality assurance inspections, in manufacturing, underscore the importance of quality. We are certified according to IATF in all locations.
