This high-torque, zero-backlash bellows coupling is ideal for responsive systems in industries such as semiconductor, solar, test and measurement, and printing equipment. Its lightweight, low-inertia design and stainless steel bellows enable smooth operation and flexibility under torsional loads, accommodating all types of misalignment. The keyed clamp type coupling features anodized aluminum hubs and keyways for increased torque capacity and secure shaft engagement. With a balanced design for reduced vibration at high speeds, this coupling is suitable for applications requiring precision and reliability, such as robotic arms, CNC machinery, and precision assembly equipment.
Top product features:
High torque zero-backlash capability
Keyways for increased torque capacity and anti-slip functionality
Four convolution bellows design for higher torque and torsional stiffness capabilities
Ruland standard length bellows couplings are a high torque zero-backlash coupling commonly found in responsive systems on semiconductor, solar, test and measurement, and printing equipment. This keyed clamp type bellows coupling consists of two anodized aluminum hubs and a stainless steel bellows creating a lightweight low inertia coupling. The addition of keyways allows for increased torque capacity and prevents the coupling from slipping on the shaft when over torqued. It has 0.625" x 0.625" bores, 3/16" x 3/16" keyways, 1.313" OD, and 1.688" length. This coupling has a four convolution bellows for higher torque and torsional stiffness capabilities than equivalent couplings with more convolutions. The bellows are able to flex while remaining rigid under torsional loads allowing for all types of misalignment to be accommodated. This bellows coupling has a balanced design for reduced vibration at high speeds of up to 10,000 RPM. Hardware is metric and tests beyond DIN 912 12.9 standards. It is RoHS and REACH compliant.
