GERWAH® LHS, LHD and LHC: The advantages of the system
1. No tooth backlash
An important property for synchronous operation or for machines that are frequently used in start/stop or reverse operation. GERWAH® couplings are ideally suited to applications in which the positioning accuracy of the control system in both directions is important.
2. Torsional stiffness
The design of the coupling guarantees a high level of torsional stiffness, which is an important property for applications in packaging machines, servomotors drives, printing presses and machine tools.
3. High temperatures
GERWAH® couplings can be used under extreme temperature conditions up to 240 °C/460 °F, e.g. in high-temperature fluid pumps.
4. High speeds
Due to the very strict production tolerances, GERWAH® allows precise vertical alignment and a high level of true running accuracy, making it ideal for applications involving high speeds even with irregular rotary forces.
5. High service life
The highly accurate disc pack insures optimum force distribution, while its flexibility also protects against vibrations from the drive. GERWAH® couplings do not wear, so that a long service life is guaranteed
6. Maintenance-free operation
GERWAH® couplings are maintenance-free and do not require greasing or cleaning

Permanently backlash-free attachment of the multiple-disc coupling by means of RINGFEDER Locking Assemblies
- Multiple-disc coupling for compensating of axial and angular misalignments. Versions with 2 disc packs can also be used to compensate for radial misalignments.
- Overall length adaptable to customer requirements through the use of various distance pieces
- High torsional stiffness
- High transmissible torques
- Can be used up to temperatures of approx. 240 °C/460 °F
- Maintenance-free operation
Many applications for GERWAH® couplings require special spacer lengths and dimensions. We can supply spacers with lengths of up to 5m.
Higher rotational speeds and/or special couplings
A coupling sometimes needs to fulfil certain industrial safety standards or is operated at very high rotational speeds. We can also provide solutions for this.
