Metal Bellows Coupling

Since 1957 our custom engineered parts have made the impossible possible providing clients accurate dependable and reliable solutions for any application challenge.

Metal bellows coupling. Highly precise torsionally stiff backlash free the world s leading metal bellows couplings of the ringfeder gwb series formerly gerwah are ideal for all applications in which torques or rotary movements must be transmitted from shaft to shaft with highest angular accuracy. Servometer currently offers two bellows technologies. Servometer is a preeminent manufacturer of quality crafted metal bellows couplings electroforms and electrical contact springs. The corrugations absorb axial forces that are created by thermal expansion as the motor heats up meaning bellows couplings can handle higher operating temperatures than elastomer couplings.

The thin wall of the bellows allows the coupling to remain flexible under misalignment conditions while maintaining rigidity under torsional loads. With a bellows between two hubs these couplings handle all types of misalignment and are good for precision stepper and encoder motion control applications. Aluminum hubs with stainless steel bellows. Bellows coupling ruland bellows couplings are comprised of two anodized aluminum hubs and a stainless steel bellows.

Misalignment compensation with zero backlash comprised of two end hubs with set screws or integral clamps that fasten to a shaft our stainless steel bellows couplings utilize hydroformed corrugated flex members to compensate for axial angular and radial shaft misalignment. Bkm metal bellows coupling with clamping hub. Bwc series overview. Inside diameter possible from ø to ø h7 mm d 1 d 2.

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. If you don t find a standard product that meets your application requirements we can design a custom product for you. Standard bellows style coupling. All have lightweight aluminum hubs and a stainless steel bellows for corrosion resistance.
