IKO Separable Roller Follower- Metric, NAST40R, Crowned OD, Open, 40 mm Bore, 80 mm OD
IKO Separable Roller Follower consists of inner ring, needle roller cage and thick-walled outer ring to withstand heavy rolling or shock loads. These parts can be easily separated providing an easy handling. Roller Followers are available with Crowned or Cylindrical outer rings. The crowned outer ring relieves edge load created by mounting error and the cylindrical is suitable for applications with large loads or low track surface hardness due to a large contact area with mating track surface. Adequate lubrication is requested as pre-packed grease is not provided. Sufficient lubrication is needed between cam followers and steel track on which cam followers run, to prevent seizure and to reduce friction.
