FAQ

Question?

What is the correct procedure for tightening the lock nut on the H309 sleeve?

Answer: The lock nut should be tightened until the required reduction in radial internal clearance of the bearing is achieved. This is often done using the drive-up method with a hook spanner or by measuring the axial displacement. Refer to the FAG mounting instructions for specific values based on the bearing type.

Question?

Which bearings are compatible with the FAG H309 adapter sleeve?

Answer: The H309 sleeve is compatible with bearings having a 45mm tapered bore, such as self-aligning ball bearings (e.g., 1309 EKTN9), and spherical roller bearings (e.g., 21309-E1-K, 22209-E1-K, 22309-E1-K).

Question?

How can I ensure the correct axial drive-up distance when mounting a bearing with this sleeve?

Answer: The axial drive-up distance is critical for achieving the correct operational clearance. It is typically measured from the position where the bearing bore makes firm contact with the sleeve. The exact distance depends on the bearing type and size and can be found in the manufacturer's technical documentation or mounting tables.
