Radial Loads
Couplings of this type have an integrated bearing (1) for saving
the drive elements. When mounting it is very important to observe the radial forces (2). By compliance measurement (Srad) the op-
• suitable for belt drive
timum power division between the rows of balls is guaranteed.
• clutch system: hardened steel
ln offset mounting it recommends that an additional ball or plain
• available function-systems:
bearing must be installed.
