Keyless locking couplings form d stainless steel

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 selfcentring 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. Tolerances Shaft diameter and hub hole Form A ±0.04 mm. Form B ±0.08 mm. 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.

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

D1 and D2 are customer specific e.g. 230122025; D1 = 5H7, D2 = 8H7 Note Zero backlash, torsionally rigid, resiliently flexible and maintenancefree full metal coupling for transmitting angle synchronous rotary movement. The innovative slit structure makes possible a very good axial, radial and angular flexibility with low reset force. Ideal for servomotors. Assembly Recommended shaft tolerances h7.
