Clamp Bellows Cplg, Bores 0.625"x12mm, OD 1.313", L 1.688", Aluminum
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, even at high speeds of up to 10,000 RPM. The coupling's balanced design and four-convolution bellows provide superior torsional stiffness and misalignment capabilities. Made from anodized aluminum and stainless steel, it is RoHS and REACH compliant. Perfect for applications requiring high precision and reliability, this coupling is suitable for use in a variety of industries, including aerospace, medical, and industrial automation.
Top product features:
- High torque zero-backlash coupling
- Four convolution bellows design for higher torque and torsional stiffness capabilities
- Balanced design for reduced vibration at high speeds of up to 10,000 RPM
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 clamp type bellows coupling consists of two anodized aluminum hubs and a stainless steel bellows creating a lightweight low inertia coupling. It has 0.625" x 12mm bores, 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.
