RULAND BELLOWS TYPE SHAFT FLEXIBLE COUPLINGS

TORSIONALLY STIFF COUPLINGS FOR SHAFTS 3 TO 25MM

The RULAND type MBC  bellows couplings are part of the Techdrives range of shaft couplings.  They are a precision couplings with high rigidity for torques 2.5 to 45 Nm and shafts 3 to 25 mm.  Bellows couplings have very low inertia and can operate in ambients -45 to 90°C.


Bellows couplings combine stainless steel bellows and black anodized aluminium hubs to offer superior performance in motion control applications. The bellows are made of stainless steel, which makes them ideal for transmitting torque. Due to the bellows' thin walls, the coupling is able to flex easily while remaining rigid under torsional loads. Parallel misalignment, angular misalignment and axial motion are accommodated by the bellows coupling.


The combination of aluminium hubs with the bellows results in an extremely lightweight, low inertia coupling. Zero backlash and a long, maintenance-free life are assured since the bellows coupling has no moving parts. An important feature of the bellows coupling is a balanced design to reduce vibration in high speed applications of up to 10,000 rpm. Bellows couplings are especially suited for high-end servo, stepper, encoder and positioning applications.


Type:  One piece all-metal coupling with very high torsional stiffness and zero backlash.

Construction: Stainless steel bellows with aluminium alloy clamp style hubs.

Applications:  Small high performance servo drives, precision measuring equipment
