Flexible Bellows
kasin
Bellows couplings are especially suitable for direct connections between two coaxial shafts. The metal bellows define the characteristics of the coupling and compensate for lateral, axial, and angular shaft misalignment with low restoring forces.Bellows couplings are especially suitable for direct connections between two coaxial shafts.

Bellows couplings
Highly precise, torsionally stiff, backlash-free – the world's leading metal bellows couplings of the kasin ® GWB series – formerly GERWAH® GWB – are ideal for all applications in which torques or rotary movements must be transmitted from shaft to shaft with highest angular accuracy: In linear and spindle lifting units of machine tools and packaging machines, in medical and pump technology, in test benches, in automation, conveyor and control technology, in robotics and much more.
Features:
easy to mount low moment of inertia low cost
Material:
Bellows made from highly flexible, high grade stainless steel; see below for hub material
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 forces the clamp into the open position for easy mounting and dismounting
Absolutely backlash free due to frictional clamp connection
Temperature range: -30 to +100° C (-22 to +212° F)
Speeds:
Up to 10,000 rpm; in excess of 10,000 rpm with finely
balanced version (up to G = 2.5)
Service life:
Maintenance free with infinite life when operated within the technical specifications
Brief overloads:
Acceptable up to 1.5x the rated torque
Fit tolerance:
Overall clearance between hub and shaft 0.01-0.05 mm
Nonstandard applications:
Custom designs with various tolerances, keyways, materials, dimensions, etc. available upon request
