Keyed Clamp Bellows Cplg, Bores 25x15mm, OD 2.250", L 3.200", Alum
For high-torque applications in responsive systems, Ruland's Keyed Clamp Bellows Cplg offers a lightweight, low-inertia solution. This zero-backlash coupling features anodized aluminum hubs and a stainless steel bellows that flexes while remaining rigid under torsional loads, accommodating all types of misalignment. With a four-convolution design and balanced construction, it provides high torque and torsional stiffness capabilities, reducing vibration at high speeds of up to 10,000 RPM. Suitable for semiconductor, solar, test and measurement, and printing equipment, this coupling is ideal for applications requiring high precision and reliability, including robotic systems, CNC machines, and precision machinery.
Top product features:
- High torque zero-backlash coupling for responsive systems
- Four convolution bellows design for higher torque and torsional stiffness capabilities
- Keyed clamp type design with keyways for increased torque capacity and prevention of slipping on the shaft
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 25mm x 15mm bores, 8mm x 5mm keyways, 57.2mm OD, and 81.3mm 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.
