Mini Keeper 　MK　Handling

Installing to the shaft

  • 1. The shaft bore of the Mini Keeper is already finished. A tolerance for the installation shaft diameter of h7 or h8 is recommended.
  • 2. Use the pin pocket (groove) on the end face of the hub to connect the Mini Keeper to the shaft. Insert the pin into the shaft, and then set them in the pin pocket as shown below. The clearance should be about 0.5 mm.

Make sure to set a clearance between the pin end face, side, and pin pocket. Pin bore machining differs depending on the sort of pin

Installing onto a driven member

  • 1. Use the flange jaw to attach the Mini Keeper to a driven member (gear, pulley, etc.). Cut a groove into the end face of the driven member, and slide the jaw into it.
    At this time, be sure to allow a clearance so that thrust and radial loads do not act on the flange end face including the jaw. The clearance should be about 0.5 mm.

Torque Setting

  • 1. The Mini Keeper is shipped at a zero-point (minimum torque) setting.
    The scale on the outer circumference of the adjustment nut should be aligned with the mark as shown below. Torque Setting
  • 2. Set the torque by tightening the adjustment nut. Refer to the torque curve (click here).
    Use the torque scale as a guide for setting the torque as shown below.

    Be sure to check with the actual equipment to confirm that the set torque is appropriate.

  • 3. After setting the torque, fix the adjustment nut to stop it from rotating. Simply insert the supplied anti-rotation clip between the adjusting nut and the stop collar as shown below.
    Make sure that the protrusions of the anti-rotation clip are securely positioned in the hub grooves on both sides. The antirotation clip is placed against the stop button (convex part) of the adjusting nut to prevent rotation. Torque Setting

Note )1. Water, oil, or other contaminants on the friction surface can cause torque irregularities and prevent stable slipping torque.

Note )2. The Mini Keeper is intended for use when the ambient temperature is less than 35°C. Contact a Tsubaki representative if the ambient temperature is higher.
