Description

Material

Stainless steel 1.4305.

Version
Bright.
Note
Backlash-free, torsionally stiff, flexurally elastic and maintenance-free all-metal coupling for the transmission of angularly synchronous rotary movements. The innovative slot structure enables very good axial, radial and angular flexibility with low restoring forces. Best suited for servomotors. With clamp hub for shaft fastening.

These stainless steel beam couplings are particularly suitable for the foodstuff and pharmaceutical industries.
Temperature range
-50 °C to +150 °C.
Assembly
The beam couplings have a H7 tolerance. The recommended clearance tolerance is 0.02 - 0.05 mm. This tolerance and lubricating the shaft journals aids assembly and removal.
On request
Desired hub holes D1 and D2 seperately with tolerance class or tolerance zone.
DIN 6885 keyway.
