Drawn Cup Roller Clutches Metric Series
  • For proper application, separate bearings are suggested (adjacent to the clutch) to carry radial loads and assure concencentricity between shaft and housing.
  • The Clutch engages when housing is rotated relative to the shaft in direction of arrow marking (<LOCK), as labeled on cup.
  • Proper inspection requires use of ring gage and bore plug gage(s) See page B3-9 
  • Full details on installation are given on page B-3-8.
  • Shaft raceway and housing bore diameters that are nessary for mounting and operation are listed on the opposite page.
  • Type FC clutches have springs integrally molded with the cage position the rollers for lockup.
  • Type FCS-FS, FC-K clutches have stainless steel springs inserted into the molded cage to position the rollers for lockup.
  • The mounted clutch engages when the housing is rotated relative to the shaft in the direction of the arrow marking (<Lock) stamped on the cup.
The mounted clutch engages when the housing is rotated relative to the shaft in the direction of the arrow marking stamped on the clutch. When manufactured the outer cup of the clutch is accurately drawn from strip steel, it can go slightly out of round durning heat treatment. When the assembly is pressed into a ring gauge or properly prepared houding of the correct size and wall thickness, it becomes round and is properly sized. The proper inspection procedure is as follows:
  1. Press the assembly into a ring gauge of the proper size as given in the tabular data.
  2. Gauge the bore with the specified plug gauges of the proper size, as given in the tables of diamensions.
  • a. The locking plug is rotated to insure lockup when the clutch is operated on low limit shaft and ids mounted in high limit housing strong enough to properly size the clutch.
  • b. The overrun plug is rotated to insure free overruning when the clutch is operated on high limit shaft and is mounted in a low limit housing.
  • c. The go plug and no go plug insure proper size of the bearings in the clutch and bearing assemblies.
