Overview
Lock nut / lock ring
Lock nuts (lock rings) are locking elements that secure a bearing axially on a shaft or on an adapter/withdrawal sleeve. Used together with a locking washer or clip to prevent unintentional loosening, they can be reused if undamaged.
Key features
- Secure a bearing axially
- Used with locking washer/clip
- Prevent unintentional loosening
- Reusable if undamaged
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.
