Outer ring for drawn cup needle roller bearing is made of cold rolled strip accurately formed.Strcture of DC needle roller bearings features space saving and higher capacity .They are suitable for aoolications 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℃
