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. Theoperating 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 touse 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.
