Bellows Couplings suit high rpm applications.
Press Release Summary:
Intended for motion control applications, Bellows Couplings feature balanced design with stainless steel bellows and aluminum hubs. Parallel misalignment, angular misalignment, and axial motion are accommodated by bellows. Since couplings have no moving parts and zero backlash, maintenance-free life is assured. Six outside diameters range from 19/32-2 in. in set screw style and Nomar clamp style. Inch and metric bore sizes from 1/8-1 in. are available.

Ruland Bellows Couplings - Ideal in Applications with High RPM
Marlborough, Massachusetts, October 2005. Ruland Manufacturing Co., Inc.offers bellows couplings that combine stainless steel bellows and aluminum hubs for highly accurate performance in motion control applications. The properties of stainless steel bellows make them ideal for transmitting torque with a high level of torsional stiffness. The thin walls of the bellows allow the coupling to flex easily, yet remain rigid under torsional loads. Parallel misalignment, angular misalignment and axial motion are accommodated by bellows.
The combination of aluminum hubs with the bellows results in an extremely lightweight, low inertia coupling. Since the couplings have no moving parts, zero backlash and a long, maintenance free life are assured. An important feature of the couplings is a balanced design to reduce vibration in high rpm applications. Applications include encoders, where the high accuracy of these couplings ensures optimal performance, and servomotors, where the torque capabilities as well as the accuracy of these couplings are required.
The couplings are available from stock in a choice of six outside diameters from 19/32" (15mm) to 2" (50mm) in both set screw style and Nomar clamp style. A large variety of inch and metric bore sizes from 1/8" (3mm) to 1" (25mm) is available, allowing the end user to mix and match to select the combination of bores required for the application. Stainless steel hubs, keyways, and other custom features are available by special order.
Bellows couplings are part of Ruland's complete product line which includes shaft collars, rigid couplings and five types of zero-backlash motion control couplings: beam couplings, bellows couplings, Oldham couplings, miniature disc couplings and curved jaw couplings.
