Assembly sequence:
1. Use flange surfaces (minimum material
strength > 900 N/mm
2
; hardness > 30 HRC) that are
clean, flat (run‐out tolerance 0.01 mm) and as pol­
ished as possible ( R
t
< 0.8).
2. Prior to installation, clean the plane flange surfaces of
the torque‐measuring disc and of the counter flanges.
For safe torque transfer, the surfaces must be clean
