Design:
One side with a single radial clamping screw ISO 4762. One side includes backlash-free clamping hub and tapered press-fit device. Any imbalance of the clamping hub, is compensated for balancing bores located on the inside of the hub. More design details
Temperature range:
-30 to +120° C (3.6 F to 270)
Backlash:
Absolutely backlash-free.
Brief overloads:
Acceptable up to 1.5 times the value specified.
Service life:
These bellows couplings have an infinite life and are maintenance-free if the technical ratings are not exceeded.
Material:
Bellows are made of highly flexible, high-grade stainless steel; clamping hubs up to series 80 aluminium, and 150 and up steel. Tapered segment on hub face: glass-fiber reinforced plastic deposited onto an aluminium hub.
Fit tolerance:
On the hub/shaft connection 0.01 to 0.05 mm.
Speeds:
Up to 10,000 rpm, in excess of 10,000 rpm available with a finaly balanced version.
Non-standard application:
Custom designs with varied tolerances, keyways, non-standard material and bellows are available upon request.
