Keyed Clamp Bellows Cplg, Bores 12x8mm, OD 33.3mm, L 42.9mm, Alum
This high-torque, zero-backlash bellows coupling is a key component in responsive systems for semiconductor, solar, test and measurement, and printing equipment. The lightweight, low-inertia design features anodized aluminum hubs and a stainless steel bellows that can flex while remaining rigid under torsional loads, accommodating all types of misalignment. With a four-convolution bellows and balanced design, it provides high torque and torsional stiffness capabilities, reduced vibration, and accommodates high speeds up to 10,000 RPM. Ideal for applications requiring 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 design allows for responsive systems in applications such as semiconductor, solar, test and measurement, and printing equipment.
- The addition of keyways increases torque capacity and prevents the coupling from slipping on the shaft when over torqued.
- The bellows are able to flex while remaining rigid under torsional loads, accommodating all types of misalignment.
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 12mm x 8mm bores, 4mm x 2mm keyways, 33.3mm OD, and 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.
