Inch Sizes - Yoke Roller 

IKO Non-separable Yoke Type Roller Follower is full complement bearing with inner ring, side plates and thick-walled outer ring to withstand heavy rolling or shock loads. Its surface is treated with black oxide coating. 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. Sufficient lubrication is needed between roller followers and steel track on which cam followers run, to prevent seizure and to reduce friction.
