One-piece rigid coupling 12x12x29x45 steel

One-piece rigid couplings made from a single element clamp the shaft, offering high torsional clamping power and avoiding the damage to shafts caused by clamps with perpendicular set screws. They are particularly recommended for applications requiring high-precision motion control and where components are correctly aligned. (Connecting countershafts or connecting a motor to a gearbox).

Ability to develop powerful torque
Absence of dead travel
Tolerance on d + .051 mm -.000 mm
Self-locking socket head cap screws
Above diameter 20, couplings are supplied with a keyway.

ASSEMBLY INSTRUCTIONS

- Align the coupling on the two shafts to be joined
- Tighten the self-locking screws to half the recommended torque
- Then tighten the screws to full torque
