Oldham Lateral Offset Couplings
Rotation is transmitted through a central disc that slides over the tenons on the hubs under controlled preload conditions to eliminate backlash. These couplings provide generous radial compensation and easy maintenance.
Hubs: Clamp Style, thro' hole, Aluminium Alloy 2014A T6
Torque Discs: Standard (no thro' hole), Acetal
- High torsional stiffness
- Good bearing properties
- Long backlash-free life
