Note
Keyless locking coupling with low mass and moment of inertia. Easy to connect and release – no jamming on the shaft. Perfect for zero backlash connections. Excellent concentricity and running. Suitable for keyed and keyless shafts.
- for shaft diameters from 5 to 35 mm
- for high torques
- minimum axial offset when mounting
- self-centring

Assembly
Shaft and hub must be free of oil, grease and dirt. Do not lubricate keyless locking coupling. Insert keyless locking coupling in the hub seat and slide onto shaft. Tighten nut by hand and use a torque wrench to tighten to the defined tightening torque.
