Needles- rollers - Import export

KIS needle roller bearings are ideal for applications that require space-saving rolling bearings with high load carrying capacity. We offer needle roller bearings in both radial and axial designs as well as in combined designs. In bearing technology, cylindrical rolling elements are referred to as needles if the rolling element diameter is ≦ 6 mm and the ratio of rolling element diameter to rolling element length gives a value Dw/lw ＜ 1:3. Radial needle roller bearings are intended exclusively for use as non-locating bearings. The given axial displacement path for bearings with an inner ring allows axial movements between the shaft and the housing. If necessary, wider inner rings are available to allow larger axial displacement paths. Our combined needle bearings are characterised by particularly high precision and efficiency. By integrating both bearings into one unit, combined needle roller bearings are often easier to press in and easier to handle than individual solutions.

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.

Similar in design to yoke type track rollers with axial guidance, our KIS cam rollers are based on needle roller or cylindrical roller bearings. Instead of an inner ring, they are equipped with a solid bolt. This serves as an inner ring replacement and is provided with a fastening thread. They are ideal for applications that require high rigidity, load carrying capacity and guiding accuracy. Our stud type track rollers are used, for example, in conveyor technology, machine tools and medical technology. Depending on the application requirements, the KIS range offers a wide variety of designs. We are happy to advise you on the right solution for your application!

Our yoke type track rollers are available as single or double row needle roller or cylindrical roller bearings. Depending on the application requirements, the KIS range offers different ready-to-fit variants. Equipped with particularly thick-walled outer rings, our yoke type track rollers can support high radial loads and tolerate axial loads from minor misalignments, skewed running or short-term start-up shocks. Yoke type track rollers are mounted on axles and supported on a flat raceway (mating track). To meet specific requirements, we offer a wide range of different variants. Together with you, we develop the customised KIS solution carefully considering the use of cages, rib rings, seals and the profile of the outer ring running surface.
