The design of IKO ThrustDisk Seals TM prevents grease from flowing out, and foreign
substances from entering into the bearing. This unique design prevents metal contact
between the outer ring and side plate caused by mounting errors, which can improve thelife of the bearing.

Remarks
1. No oil hole is provided if the stud diameter d1 is 6.35 mm or less. An oil hole is provided for the outside surface and the end of the stud on other models.
2. Grease (Shell Lubricants Japan K.K. ALVANIA GREASE S2) is prepacked.
3. For the maximum allowable static load, please contact IKO.
4. This product includes a hexagon nut. If the nut should become loose, use a spring washer, self-locking nut, etc.

5. A mounting hole with a tolerance class of F7 is recommended for mounting the stud. The mounting hole diameter should be prepared without play in the fit area, especially when shock loads are applied.
6. The operating temperature range is from -20 to 80°C.
7. The allowable rotational speed is around d1n=42000 for grease lubrication, and around d1n=70000 for oil lubrication. If an axial load is applied, it is recommended to use 1/10 the d1n value.
8. When mounting, do not hit the cam followers directly with a hammer, etc. It may lead to rotation failure or cracking.
