Keyless locking couplings with central nut

Coupling stainless steel 1.4057. Screws stainless steel 1.4301. For applications that require a small construction volume and low surface pressure. The keyless locking coupling can be fully recessed in a hub connection. for shaft diameters 6 20 mm suitable for hubs with low wall thickness minimum axial offset possible selfcentring 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 h8. Surface quality Rz ≤ 16 µm. Hub Recommended tolerance H8. Surface quality Rz ≤ 16 µm.

Particularly compact selfcentring keyless locking coupling without axial offset. for shaft diameters from 8 to 85 mm for medium torques suitable for hubs with low wall thickness no axial offset selfcentring 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 h8. Surface quality Rz ≤ 16 µm. Hub Recommended tolerance H8. Surface quality Rz ≤ 16 µm.

Universal joints with plain bearing can be swivelled by 45°. Max. transferable torque (Nm) at 150 rpm, operation angle α < 5°. * Bore depth is less than by DIN 808.

Shrink disc to connect a hollow hub to a shaft. They are mounted on the OD of the hub and generate pressure on the hub wall by reducing the ID with wedgeformed rings, creating a press fit between the hub and shaft. They are suitable for static, dynamic and shock loads. for extremely high torques no axial shaft/hub offset when assembling selfcentring The version 23380014072 has high tensile ISO 4762 screws. Assembly Remove existing transportation locks. Clean and lightly oil shaft, internal and external hub diameters. Do not use MoS2 or grease. Slide shrink disc onto hub. Then slide unit (shrink disc/hub) onto shaft and position correctly. Gently tighten clamping screws one after the other by hand. Then use a torque wrench to tighten the clamping screws crosswise in several increments to the defined tightening torque MS. 1st increment approx. 33% MS 2nd increment approx. 66% MS
