Overview
Lock rings and spacer washers are precision hardened-steel parts that axially position a bearing on its shaft or in its housing. Tab washers (MB and MBL series), plain spacer rings, and stabilizing rings absorb the tolerance stack-up between the bearing, the shoulder, and the retaining nut and prevent the bearing from drifting axially in service.
Common forms include MB / MBL tab washers paired with KM / HM lock nuts, plain spacer rings cut to precise thickness, and stabilizing rings with a keyed inside diameter. All are case-hardened for fatigue resistance against the rotating inner ring face.
Key features
- Precision-ground thickness for exact axial positioning
- Case-hardened steel to resist fretting against bearing ring
- Matched to specific bearing series or housing bore
- Many are consumables — replaced every time the bearing is serviced
Typical applications
- Axial clamping of tapered-bore bearings on adapter sleeves
- Stack-up spacing in multi-bearing shaft arrangements
- Retention of inner race against shaft shoulder
- Replacement of worn original-kit hardware during overhaul
Selection guidance
Identify by bearing part number and position (inboard / outboard) — dimensions and hardness class must match the bearing manufacturer's assembly drawing.
