 Needle roller bearings, drawn cup

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℃.

1. Structures of various series of drawn cup needle rollers
     Metricseries: HK, BK, F, FH, FY, MF, MFH, MFY
     Inch series: SCE, BCE, SCH, BCH,SN, B, BH, M, MH

     HK: Caged, with open ends
     BK: Caged, with open ends
     F   : Full complement, with open ends
     FH : Full complement, with openends(Heavy series)
     FY : Full complement, grease retained, with openends
     MF : Full complement, with closed ends
     MFH: Fullcomplement, with closed ends(heavy series)
     MFY: Full complement, withclosed ends
     SCE: Caged, with open ends
     BCE: Caged, with closedends
     SCH: Caged, with open ends(heavy series)
     BCH: Caged, withclosed ends(heavy series)
     SN   : Full complement, grease retained, withopen ends
     B      : Full complement, with open ends
     BH   : Fullcomplement, with open ends(heavy series)
     M      : Full complement, withclosed ends
     M H : Full complement, with closed ends (heavyseries)

2. Inspection the enveloping circle diameter

    The dimensional accuracy of drawn cup needle roller bearings can not bemeasured before fitting
    without a ring gauge as the thin-walled outerring can be out of round due to the manufacturing process.
    The bearingsobtain the accuracy required for their correct function only when pressed into ahousing
     bore which must be manufactured with the recommended 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 to thatgiven.

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