Keyed Clamp Bellows Cplg, Bores 0.625"x0.375", OD 1.313", L 1.688", Alum
This high-torque, zero-backlash bellows coupling is ideal for responsive systems in semiconductor, solar, test and measurement, and printing equipment. Its lightweight, low-inertia design allows for smooth operation at high speeds of up to 10,000 RPM, while its balanced design reduces vibration. The keyed clamp type coupling features a stainless steel bellows and anodized aluminum hubs, providing increased torque capacity and preventing slippage on the shaft. Suitable for applications requiring high torsional stiffness and misalignment accommodation, this coupling is perfect for demanding industries where precision and reliability are crucial. It is also RoHS and REACH compliant.
Top product features:
- High torque zero-backlash coupling
- Keyed clamp design allows for increased torque capacity and prevents the coupling from slipping on the shaft when over torqued
- Four convolution bellows design provides higher torque and torsional stiffness capabilities than equivalent couplings
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 0.375" bores, 3/16" x 3/32" 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.
