Keyed Clamp Bellows Cplg, Bores 12x12mm, OD 50.8mm, L 58.7mm, Alum
For responsive systems in high-tech industries, Ruland's Keyed Clamp Bellows Coupling offers high torque and zero-backlash performance. This lightweight, low-inertia coupling features anodized aluminum hubs and a stainless steel bellows, allowing for flexibility and rigidity under torsional loads. Its balanced design reduces vibration at high speeds up to 10,000 RPM, making it ideal for semiconductor, solar, test and measurement, and printing equipment. The coupling's increased torque capacity and keyway design prevent slipping on the shaft, accommodating various types of misalignment. Its compact size and high-performance capabilities make it a reliable choice for demanding applications.
Top product features:
- High torque zero-backlash coupling
- Creates a lightweight low inertia coupling with two anodized aluminum hubs and a stainless steel bellows
- Has a 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 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 12mm bores, 4mm x 4mm keyways, 50.8mm OD, and 58.7mm 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.
