Matching Components

KM9 lock nut is normally used together with the following components:

Lock washer: MB9 — bent into the KM9 slots after tightening to prevent loosening.
Adapter sleeve: H309 / H2309 — for mounting 45 mm bore tapered-bore bearings. Confirm sleeve compatibility with the specific bearing model before ordering.
Hook spanner: HN9 / HN9-10, depending on the tool specification.

If you are replacing an existing lock nut, send us the original part number, thread size or a photo, and we will help confirm the matching washer and sleeve combination.
