Preparation
Do not use lubricating pastes, other high-pressure additives or oils and greases containing molybdenum disulphide. Use Vaseline, for example.
The use of unsuitable lubricants can lead to incompatibility with the elastomer ring and impair the functionality.
 | Facilitated assembly The bores in the coupling hub have an H7 fit. Beckhoff recommends play of 0.1 – 0.5 mm between the coupling hub and the shaft. The fitting tolerance and the oiling of the shaft journals simplify the assembly and disassembly of the coupling. |
Check the shaft connection dimensions and the tolerances. Make sure that the shafts to be connected and bores in the hub are clean and free from burrs. Adhere to the fitting tolerance and oil the shaft journals prior to assembly.
When pushing the coupling hubs together, the compressive prestressing of the elastomer ring requires an axial mounting force. The axial force can be reduced after cleaning the elastomer ring and by lightly oiling the contact surfaces.
