Needle roller bearings, needle roller and cage assemblies
Needle roller and cage assemblies are ready-to-mount, self-contained bearing components. 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.
Standard needle roller and cage assemblies.
Supplies needle roller and cage assemblies in single row and double row designs. They are characterized by:
– a simple and rugged design
– accurate guidance of the rollers in the cage pockets
– good running performance
Outer ring for drawn cup needle roller bearings(DC type) is made of cold rolled steel strip accurately formed.
Structure of DC needle roller bearings features space saving and higher capacity.They are suitable for applications with limited space and housing not hard enough to act as raceway. No requirement on axial location when the DC needle roller bearing is pressed into the housing.
In most applications inner ring is not necessary for DC needle roller bearings unless shaft raceway is impractical,standard inner rings for DC to compare with open end DC needle roller bearings, close end DC needle roller bearings are good for sealing at the close end of bearings,operating temperature range for bearings grease lubricated are 20℃ to +120℃.
