Needle roller bearings, drawn cup
Outer ring fordrawncup
needle roller bearings(DC type) is made of coldrolledsteel strip accurately formed.Structure of DC needle roller bearingsfeaturesspace saving and higher capacity.They are suitable for applications withlimitedspace and housing not hard enough to act as raceway. No requirement onaxiallocation when the DC needle roller bearing is pressed intothehousing.
In most applications inner ring isnotnecessary for DC needle roller bearings unless shaft racewayisimpractical,standard inner rings for DC to compare with open end DCneedleroller bearings, close end DC needle roller bearings are good for sealingat theclose end of bearings,operating temperature range for bearings greaselubricatedare 20℃ to +120℃.

2. Inspection the enveloping circle diameter
The dimensional accuracy of drawn cup needle roller bearings cannotbemeasured before fitting
without a ring gauge as thethin-walledouterring can be out of round due to the manufacturingprocess.
Thebearingsobtain the accuracy required for their correctfunction only whenpressed into ahousing
bore which must be manufacturedwith therecommended tolerancelimits.
The enveloping circle diameter can then be checked as follows:
a. Press the bearing into a steel ring gauge(wall thickness≥20mm).Thebore dimension of the ring
gauge must correspondtothatgiven.
b. Measure the enveloping circle diameter with cylindrical goandno-gogauge plugs.
