Keyed Clamp Bellows Cplg, Bores 0.625"x12mm, OD 1.313", L 1.688", Alum
Ruland's Keyed Clamp Bellows Coupling is a high-performance, zero-backlash coupling ideal for responsive systems in industries such as semiconductor, solar, test and measurement, and printing. This lightweight, low-inertia coupling features anodized aluminum hubs and a stainless steel bellows, allowing for increased torque capacity and preventing slippage on the shaft. With a four-convolution bellows design, this coupling accommodates all types of misalignment and provides balanced performance at high speeds up to 10,000 RPM. Suitable for applications requiring high torque and torsional stiffness, this coupling is RoHS and REACH compliant, making it a reliable choice for demanding industrial environments.
Top product features:
- High torque zero-backlash coupling for responsive systems
- Anodized aluminum hubs and stainless steel bellows create a lightweight low inertia coupling
- Keyways allow for increased torque capacity and prevent the coupling from slipping on the shaft when over torqued
Top product applications:
- Semiconductor equipment
- Solar equipment
- Test and measurement equipment
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 12mm bores, 3/16" x 4mm keyways, 1.313" (33.3mm) OD, and 1.688" (42.9mm) 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.
