Description

Material

Steel.
Stainless steel 1.4305.

Version
Steel black oxidised.
Stainless steel bright.
Note
Rigid couplings transmit high torques backlash-free and with high rigidity. They are used where there are no shaft misalignments or alignment errors. Wear and maintenance-free.

Transmission of the max. nominal torque is only achieved through optimum installation and dimensional accuracy of the shafts.

Max. speed 4000 rpm.

Due to a technical alteration, some of the rigid couplings may still be supplied without offset screws (all screws screwed in from above).
Temperature range
-40 °C - +175 °C.
On request
Other dimensions.
Version with DIN 6885/1 parallel keyway, tolerance P9.
