Needle Roller Bearing and Cage Assemblies
Product Description
needle roller and cage assemblies are readyto contained bearings. They are an excellent choice for applications that require a very rigid bearing arrangement as well as a high load carrying capacity. If the shaft and housing bore can serve as raceways, needle roller and cage assemblies require minimal radial space.
Basic design bearings
basic design needle roller and cage assemblies are identified by the series designation K and available in single row and double row designs. They are characterized by the following properties:
· simple and rugged design
· accurate roller guidance in the cage pockets
· good running performance
