Bellows Couplings BK

Please select a Metal Bellows Coupling:

Bellows coupling model BKH
with split hub from 15-1,500 Nm

  • for radial mounting
  • suited for space restricted
    installations
  • low moment of inertia
  • fine balanced up to 40,000 RPM

Design:
Both clamping hubs are completely separable,
due to split hubs and two radial screws ISO 4762 on each hub. Any imbalance of the clamping hubs is compensated for by balancing bores located on the hub.

Temperature range:
-30 to +120° C (3.6 F to 270)

Backlash:
Absolutely backlash-free due to frictional clamp connection.

Speeds:
Up to 10,000 rpm, in excess of 10,000 rpm available with a finaly balanced version.

Service life:
R+W couplings are maintenance-free and have an infinite life if the technical ratings are not exceeded.

Fit tolerance:
On the hub/shaft connection 0.01 to 0.05 mm.

Brief overloads:
Acceptable up to 1.5 times the value specified.

Material:
Bellows are made of flexible, high-grade stainless steel. The hubs are made from aluminium.

Non-standard application:
Custom designs with varied tolerances, keyways, non-standard material and bellows are available upon request.

Technical Data:

  • rated torque from 15 - 1,500 Nm
  • shaft diameter from 8 - 80 mm
