Bearing accessories
How a bearing attaches to the shaft and how it is held there matters as much as the bearing itself. A sleeve seats a tapered-bore bearing on a plain shaft, a lock nut and washer hold the axial position, and a withdrawal sleeve lets it come off without being forced. A badly tightened lock nut will finish a correctly chosen bearing early.
Types and variants
The distinct designs that sit under this category.
Adapter sleeves (H, HE, HA)
Mount a tapered-bore bearing on a plain shaft, tightened with a lock nut.
Withdrawal sleeves (AH, AOH)
The opposite of an adapter — they keep the bearing removable on the shaft.
Lock nuts (KM, KML, HM)
Locate the bearing axially — always used together with a lock washer.
Lock washers and snap rings (MB, MBL, W)
Stop the nut from working loose under vibration.
Where it is used
The applications this category most often serves.
- Shaft attachment in plummer block housings
- Mounting spherical roller bearings
- Seating tapered-bore bearings on plain shafts
- Ease of removal during scheduled maintenance
What we ask when selecting
What we need in order to find the right part. You do not need all of it — we can work out the rest together.
- Shaft diameter and taper
- Is the bearing bore a 1:12 or a 1:30 taper? The sleeve follows from that.
- Adapter or withdrawal sleeve
- The bearing position on the shaft and the removal direction decide it.
- Matching nut and washer
- A KM nut pairs with an MB washer — the size numbers go together.
Typical designations
Examples that make the designation readable — not a stock commitment.
- H 317
- Adapter sleeve for a 2317 or 22317 K bearing.
- AH 3130
- Withdrawal sleeve for a 23130 K spherical roller bearing.
- KM 17 + MB 17
- Lock nut and its matching washer — used as a pair.

Send us the designation or the dimensions — we will find the match.
A code you cannot find in the catalogue, a faded marking on an old bearing, or just the dimensions — any of the three is enough. The wrong bearing costs more than a late one.
