Drawn cup needle roller bearings

Drawn cup needle roller bearings, as the name suggests, are needle roller bearings with a deep drawn, thin-walled outer ring with either open ends or a closed end. They are characterized by a very low sectional height and high load carrying capacity. Drawn cup needle roller bearings are typically used in applications where the housing bore cannot be used as a raceway for a needle roller and cage assembly, but where a very compact and economical bearing arrangement is required.

Generally, drawn cup needle roller bearings have a recommended maximum operating temperature of 140 °C, unless otherwise stated in the relevant sections in this chapter. The maximum operating temperature is limited by the seal and cage materials and the applied grease.

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℃.

Inspection the enveloping circle diameter

The dimensional accuracy of drawn cup needle roller bearings can not be measured before fitting

without a ring gauge as the thin-walled outer ring can be out of round due to the manufacturing process.

The bearings obtain the accuracy required for their correct function only when pressed into a housing
bore which must be manufactured with the recommended tolerance limits.

The enveloping circle diameter can then be checked as follows:

a.   Press the bearing into a steel ring gauge(wall thickness ≥ 20mm).The bore dimension of the ring
        gauge must correspond to that given.

b.   Measure the enveloping circle diameter with cylindrical go and no-go gauge plugs.
