For indirect drive
At indirect drives the center lines of the driving and driven side are not on the same axis. Every safety couplings for indirect drives have a mounting flange equipped with six metric threads. Toothed belt disks, gears, flanges or other extensions with high concentricity- and planning precision can be attached to the coupling flanges.
- Adjustable disengagement torque
- Very low residual moment
- Backlash-free
- High repetition accuracy
- Maintenance-free
- Automatic re-engagement after 360°
- Reliable (positive) and fast disengagement
- Very low mass inertia torque
FHW-A
The lightweight of the safety couplings: FHW-A. They are used where ease plays an important role. Because of the use of aluminium, this clutch has a very low moment of inertia.
- Entirely of aluminum and stainless steel
- Resistant coated
- Low weight
- Very low mass moment of inertia
FHW-B
The thousands of times used FHW-B comes standard with keyway and sealed deep groove ball bearings (with keyway and groove ball bearing). The hardened functional parts guarantee countless cycles and high reliability.
- With keyway and deep groove ball bearing
- Very low residual moment
- Low mass inertia torque
FHW-D
Radial space-saving and yet it meets all the requirements: FHW-D. By using a needle-camp instead of a deep groove ball bearing cluthch outer Ø is relatively small (with keyway and needle roller bearing).
- With keyway
- Small diameter by use of needle roller bearing
- Adjustable disengagement torque
- Very low residual moment
- Low mass inertia torque
FHW-F
The clamping hub FHW-F does not require machining of the shaft for keyways etc. With easy installation and high reliability proven a thousand times (with clamping hub).
- Easy assembly with clamping hub
- Very low residual moment
- Low mass inertia torque
- All working parts hardened
FHW-H
Coupling with adjustable residual moment (holding brake). This is used if the torque is only reduced and must not completely be interrupted in a case of collision. This often happens with screw driven hoisting applications (adjustable residual moment, brake with radial clampling hub).
- Adjustable residual moment (Brake)
- Low mass inertia torque
- All working parts hardened
