        Note 2) Grease replenishing hole is provided at front side only (on left side-face in the above sketch). However, in the case with "hexagon hole" no grease
             replenishing hole is provided.
        Remarks: For the cam follower with ˞marked seal, the allowable running speed is approximately 10 000 r/min.
