We recommend to inspect bores, shaft, keyway and feather key for dimensional accuracy
before assembly.
The power transmission is frictionally engaged. Fit pair of shaft-clamping ring hub is specified with H7/h6.
The following process should be observed with the assembly:
Please clean and degrease the contact surfaces of the hub bores and the shafts before assembly.
!
Oils and greases containing molybdenum disulfide or other high-pressure additives as well
as internal lubricants must not be used.
Lightly unscrew the clamping scews, shift the clamping ring hub onto the shaft of the measuring shaft and
align to dimension L
6.
Tighten the clamping screws evenly crosswise. Increase the tightening torque stepwise.
Repeat this process until the tightening torque specified in table 5 has been achieved with all clamping screws.
