R+W Bellows Coupling BK5 Type

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 with balancing bores located on the inside of the hub.
Temperature range: -30° C to +100° C (-22° F to +212° F)
Backlash: Absolutely backlash-free due to frictional clamp connection and axial pretensioning of the tapered press-fit segments.
Service life: These couplings have an infinite life and are maintenance- free if the technical ratings are not exceeded.
Tolerance: On the hub/shaft connection 0.01 to 0.05 mm.
Material:
Bellows made of highly flexible, high-grade stain-less steel
clamping hubs up to series 80 aluminium, and 150 and up steel
Tapered segment on hub face: glass-fiber reinforced plastic molded onto an aluminium hub.
Speeds: Up to 10,000 rpm, over 10,000 rpm available with a finely balanced version.
Brief overloads: Acceptable up to 1.5 times the value specified.
Properties of Bellows Coupling model BK5:
absolutely backlash-free and torsionally rigid
easy mounting and dismounting
wear-free and maintenance-free
electrically and thermally insulated
low moment of inertia
compensation for misalignment
