Description

Material
Coupling stainless steel 1.4057.

Screws stainless steel 1.4301.
Version
Bright.
Note
Keyless locking coupling for shaft and hub. Extremely small design, ideal for use in tight spaces. Self-release during dismantling.

- for shaft diameters 20 - 80 mm
- no axial offset when mounting
- not self-centring (concentricity of hub to shaft depends on the fit and length of the guide)
Assembly
Lightly oil keyless locking coupling on the tapered faces and contact points of the shaft and hub. Do not use MoS2 or grease. Insert keyless locking coupling in the hub seat and slide onto shaft. Tighten screws crosswise in several increments to the defined tightening torque.

Dismantling: Remove all screws and screw into the extraction threads of the front flange. Tighten screws crosswise in several steps until the keyless locking coupling loosens.
Tolerances
Shaft:
Recommended tolerance h11.
Surface quality Rz ≤ 16 µm.

Hub:
