Slewing Rings

Customised system or individual part solutions are our core competence at KIS. We develop complete solutions for you based on our own KIS products and combine them with our comprehensive service for drive technology. Whether it's a careful selection of individual components or proper assembly ensuring your application functions perfectly: As bearing specialists based in Germany, we’re there for every step of the process, from development and construction, through monitoring of production and assembly, to quality inspections and practical tests.

With decades of experience, we manufacture spherical roller bearings at KIS that can support large radial and axial forces in both directions. The perfect solution for applications that have to withstand massive loads. Due to the design of two rows of pendulum-shaped rollers in a common, hollow-ball raceway in the outer ring, our spherical roller bearings can support large radial and also axial forces. This makes them perfect for applications that have to withstand high loads and shocks and compensate for shaft bending or misalignment. In addition to conventional spherical roller bearings (which have no seal and have either a tapered or cylindrical bore), there are also application-specific variants developed for special requirements (e.g. sealed spherical roller bearings or bearings with optimised load ratings). Spherical roller bearings offer high performance and efficiency and are available in a wide range of sizes and designs.

We offer our KIS cylindrical roller bearings in various designs and sizes. In addition to the number of roller rows and the design of the cage, the flanges on the inner and outer rings are also considered. Due to their low friction and high rigidity, our cylindrical roller bearings are the perfect, durable solution for applications with high radial loads. They can also compensate for axial displacements (e.g. due to thermal expansion) and are available in sealed designs. Sealed cylindrical roller bearings are protected from dirt, water and dust. The seal prevents the ingress of contaminants and keeps the lubricant in the bearing. Together with you, we will be happy to develop a customised KIS solution for your requirements.

Our KIS track rollers are available as self-retaining, single or double row ball bearings with particularly strong outer rings. In addition to high radial forces, they also absorb axial forces in both directions. Track rollers are characterised by their robust construction featuring particularly thick-walled outer rings with a crowned outer surface (alternatively with a cylindrical outer surface or outer profile). They are designed to carry high radial loads and also tolerate axial loads that can arise due to minor misalignments, skewing or short-term start-up shocks. The assembly is constructed with a fixed inner ring mounted on axles. In this case, the track rollers are not installed in a housing bore, but are supported on a flat raceway (mating track). To ensure a reliable seal, the track rollers are fitted with a lip seal or cover discs on both sides. This prevents the ingress of dirt, dust and other contaminants while maintaining lubrication inside the bearing.
