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. The thin wall of the bellows allows the coupling to remain flexible under misalignment conditions while maintaining rigidity under torsional loads. If you don t find a standard product that meets your application requirements we can design a custom product for you. Bkm metal bellows coupling with clamping hub.

With a bellows between two hubs these couplings handle all types of misalignment and are good for precision stepper and encoder motion control applications. Up to 88 5 in lbs. Bwc series overview. Fit length mm c.

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. Bellows couplings are a type of flexible couplings with two clamping hubs connected by a series of flexible stainless steel or bronze bellows corrugations. Standard bellows style coupling. Servometer is a preeminent manufacturer of quality crafted metal bellows couplings electroforms and electrical contact springs.

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. Inside diameter possible from ø to ø h7 mm d 1 d 2. Electrodeposited metal bellows are manufactured in the new jersey facility whereas edge welded metal bellows are manufactured in florida through bellowstech llc servometer metal bellows are made through a unique process to create custom light weight reliable solutions under various conditions starting at less than half a. 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.

Aluminum hubs with stainless steel bellows. Up to 71 420 in lbs rad. This design creates a low inertia zero backlash coupling with long life properties. All have lightweight aluminum hubs and a stainless steel bellows for corrosion resistance.

Servometer currently offers two bellows technologies. Bellows coupling ruland bellows couplings are comprised of two anodized aluminum hubs and a stainless steel bellows. Our standard bellows shaft couplings are available in bore sizes ranging from 090 to 625 inches 2 29 to 15 88 mm with maximum torque ratings of 25 to 5000 in oz 0 1 to 19 2 n m. 20 1 000 nm.
