BKL Zero Backlash Bellows Couplings

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° C to +100° C (-22° F to +212° F)

Backlash :

• Absolutely backlash-free due to frictional clamped connection.

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 stainless steel. Hub material see table

Speeds :

Up to 10,000 rpm, in excess of 10,000 with a finely balanced version.

Non - standard applications :

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

Properties Of BKL Series Bellows Couplings :

• Economically priced
