2. 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.

Drawn cup needle roller bearings with a closed end are suitable for bearing arrangements at the ends of shafts. The profiled design of the closed end accommodates small axial guidance forces. Drawn cup needle roller bearings generally run directly on the shaft. However, in cases where the shaft cannot be hardened and ground, they can be combined with an inner ring

The drawn cup of hardened steel and the needle roller and cage assembly of these bearings form a non-separable unit. The space available for lubricant is large enough to enable long relubrication intervals.

Typically, drawn cup needle roller bearings have a single row of rollers. However, wide sizes incorporate two needle roller and cage assemblies immediately adjacent to each other with a lubrication hole in the outer ring

On request, any single row drawn cup needle roller bearing for shaft diameters of 7 mm and above can be supplied with a lubrication hole in the outer ring .

Drawn cup needle roller bearings are mounted with an interference fit in the housing bore. Therefore, shoulders or snap rings are not required to locate the bearing axially so the design of the housing bore is simple and can be produced economically.
