Operating speed must be equal or less than permissible speed. ® METALDRIVE Coupling Balancing. ® All the components of the METALDRIVE couplings are completely machined (spacer excluded) and balanced in class DIN ISO 1940-1 Q 6,3. Therefore, the balancing is unnecessary in most applications. In cases where a higher degree of balancing is required, it is important to consider: » Rotation speed and coupling diameter. » Rotation speed and intermediate shaft length. » Rotation speed and special balancing need of the machine. ® According to the requirement, METALDRIVE coupling can be statically or dynamically balanced according to DIN ISO 1940-1. As a standard, the balancing is made on the single coupling component. On specific request the assembled coupling can be balanced. Also as a standard the balancing is made before the key seat machining. The balancing after the key seat machining is made on specific request. Permissible speed could be limited by the weight and critical speed of spacers.

Misalignment ® METALDRIVE couplings with double disc packs allow axial, angular, and radial misalignment. ® METALDRIVE couplings with a single disc pack allows only axial and angular misalignment. Please note that application must not have the maximum value of axial and angular misalignment at the same time.
