Bellows Couplings Stainless Steel

Arcflex are one of the leading manufacturers of stainless steel bellows and expansion joints in the uk.

Bellows couplings stainless steel. Properties of bellows coupling model bks. 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. Bellows couplings are a type of flexible couplings with two clamping hubs connected by a series of flexible stainless steel or bronze bellows corrugations. The characteristics of the bellows coupling can be modified by varying the number and or the wall thickness of the convolutions of the bellows.

Bellows couplings are typically made from a stainless steel tube that is hydroformed or in some cases welded to create deep corrugations. This design creates a low inertia zero backlash coupling with long life properties. All stainless steel bellows are designed. 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.

We have over two decades worth of experience in the design and manufacture of stainless steel bellows and state of the art on site facilities allows us to offer a wide range of bellows suitable for any application and design requirements. This type of coupling generally has high torsional stiffness and may be used in any drive system where high levels of motion integrity are essential. And where space is restricted bronze bellows couplings are ideal. Flex b stainless steel.

For the highest accuracy nickel bellows couplings. This sheet is draw into a a tube which it then pressurized from within against a ribbed die to form a corrugated shape. Material bellows clamping hubs and clamping screws made from stainless steel. Suited for space restricted installations.

Ruland bellows couplings are comprised of two anodized aluminum hubs and a stainless steel bellows. Our coupling range is available with bore sizes from 2 mm up to 12 mm. Up to 10 000 rpm. The couplings are available with three construction options.

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. Detailed specifications upon request. With a bellows between two hubs these couplings handle all types of misalignment and are good for precision stepper and encoder motion control applications. For torque transmission stainless steel bellows couplings.

In excess of 10 000 rpm with finely balanced version up to g 2 5. If you don t find a standard product that meets your application requirements we can design a custom product for you. Misalignment compensation with zero backlash. Couplings allow zero backlash no play and grip evenly around your shaft for a strong hold without marring the shaft.

Such hydroformed bellows begin as a sheet of stainless steel or other metal.
