Bellows Couplings BK

Please select a Metal Bellows Coupling:

Bellows coupling model BKM
rigid and compact, with clamping hub

  • easy to mount
  • compact design for high torques
  • suited for space restricted installations
  • low moment of inertia

Design:
With a single ISO 4762 radial clamping screw per hub. Self opening clamp system optional: Loosening the clamping screw applies force to the pin, which will force the clamp into the open position for easy mounting and dismounting..

Temperature range:
-30 to +100° C (-22 F to 212 F)

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

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

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

Material:
Bellows made of highly flexible high-grade stainless steel. Hub material see table.

Speeds:
Standard up to 10,000
Option 1: In excess of 10,000 rpm with a finely balanced version
Option 2: in excess of 30,000 rpm, with balancing grade G = 2.5 (see table)

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

Technical Data:

  • rated torque from 2 - 1000 Nm
