FAQ

What bearings can be mounted with the H 320 adapter sleeve?
The H 320 is designed for bearings with a 1:12 taper, such as spherical roller bearings (e.g., 22220 series), self-aligning ball bearings (e.g., 1220 series), and certain toroidal roller bearings. Always verify the bearing's bore taper and diameter.

Does the H 320 come with a lock nut and locking washer?
The H 320 is the sleeve itself. The complete assembly requires a corresponding KM 20 lock nut and an MB 20 locking washer. These components are typically sold separately unless specified as a complete set.

What is the correct procedure for tightening the H 320 sleeve?
The correct mounting procedure involves advancing the lock nut a specific angle or using the SKF Drive-up Method to achieve the required reduction in radial internal clearance. Over-tightening can damage the bearing and sleeve. Refer to the SKF maintenance handbook for precise instructions.
