Note
Play-free mini metal bellows coupling with high torsional stiffness. The metal bellows compensates for axial, radial and angular shaft misalignment with low restoring forces. With grub screw for fastening to shafts.
They are primarily used when precise position and motion transmission is required, e.g. highly dynamic positioning and servo systems, rotary encoders, tachometers, potentiometers.

Temperature range
-30 °C to +120 °C.
Assembly
The metal bellows coupling hubs have an H7 tolerance. The recommended clearance tolerance is 0.02 - 0.05 mm. This tolerance and lubricating the shaft journals aid assembly and removal.
The metal bellows may be deformed max. 3 times over the permissible deflection values specified in the catalogue during assembly and removal. Avoid any use of force.

On request
Desired hub holes D1 and D2 separately with tolerance class or tolerance zone.
Keyway acc. to DIN 6885. Please observe largest possible bore by keyway.
