FAQ

The correct method involves driving the bearing up the tapered sleeve to achieve the required reduction in radial internal clearance. This is typically done by tightening the KM10 lock nut. It is crucial to use a feeler gauge to measure the clearance reduction and avoid over-tightening, which can damage the bearing.

Yes, adapter sleeves are standardized according to ISO 2982-1. An H310 sleeve from any reputable manufacturer like FAG, SKF, or NSK will have the same critical dimensions and can be used interchangeably with corresponding bearings (e.g., 22210 K) from other brands.

The MB10 lock washer is a critical safety component. After the KM10 lock nut is tightened to the correct position, one of the tabs on the outside of the washer is bent into one of the corresponding slots on the lock nut. This prevents the nut from loosening due to vibration or operational forces, ensuring the bearing remains securely mounted on the shaft.
