BOLTTE Black Oxide 45 Steel Clamp Rigid Shaft Couplings - 40-82 mm OD
BOLTTE Black Oxide 45 Steel Clamp Rigid Shaft Couplings - 40-82 mm OD
BOLTTE clamp rigid shaft couplings are machined from 45 steel with a black-oxide surface finish. The clamp construction provides a rigid connection for aligned shafts without requiring axial movement during assembly.
Rigid clamp coupling: check both bore and shaft alignment
This black-oxide 45 steel range provides a rigid shaft connection. Choose the listed outside diameter and length, then specify the finished bores for both shaft ends.
| Selection detail | What to check |
|---|---|
| OD 40 x L 44 mm | Listed with an 8–20 mm bore range. |
| OD 40 x L 50 mm | A separate length with an 8–22 mm bore range; equal OD does not mean equal capacity for machining. |
| Installation | Check shaft alignment, fit, keyway/flat requirements and clamp access. |
Will a rigid coupling compensate for misaligned shafts?
Do not use it as a flexible compensation element. Assess alignment and bearing loads, or evaluate an appropriate flexible coupling with verified operating limits.

Ordering notes
- Select the required outside diameter, overall length and supported bore range shown in the option name.
- State the finished bore required for each shaft in the order notes. If the two shaft diameters differ, list both values.
- Confirm shaft fit, keyway or flat requirements, torque, speed, alignment and operating environment before ordering.
All dimensions are in millimetres. Verify the selected dimensions against the actual shafts before installation.
