Needle roller bearings, drawn cup

Outer ring for drawncup needle roller bearings(DC type) is made of cold rolledsteel strip accurately formed.Structure of DC needle roller bearings featuresspace saving and higher capacity.They are suitable for applications with limitedspace and housing not hard enough to act as raceway. No requirement on axiallocation when the DC needle roller bearing is pressed into thehousing.

In most applications inner ring is notnecessary for DC needle roller bearings unless shaft raceway isimpractical,standard inner rings for DC to compare with open end DC needleroller bearings, close end DC needle roller bearings are good for sealing at theclose end of bearings,operating temperature range for bearings grease lubricatedare 20℃ to +120℃.

2. Inspection the enveloping circle diameter

    The dimensional accuracy of drawn cup needle roller bearings can notbemeasured before fitting
    without a ring gauge as the thin-walledouterring can be out of round due to the manufacturing process.
    Thebearingsobtain the accuracy required for their correct function only whenpressed into ahousing
     bore which must be manufactured with 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 correspond tothatgiven.

b. Measure the enveloping circle diameter with cylindrical go andno-gogauge plugs.
