Keyed Clamp Bellows Cplg, Bores 25x20mm, OD 2.250", L 3.200", Alum
The Ruland Keyed Clamp Bellows Coupling is a high-performance solution for responsive systems in semiconductor, solar, test and measurement, and printing equipment. Its lightweight, low-inertia design enables smooth operation at high speeds of up to 10,000 RPM, while its balanced design reduces vibration. The coupling's four-convolution bellows provides high torque and torsional stiffness, accommodating all types of misalignment. With a robust stainless steel bellows and anodized aluminum hubs, this coupling offers superior durability and resistance to corrosion. Ideal for applications requiring precise control and high reliability, the Ruland Keyed Clamp Bellows Coupling is a reliable choice for demanding industries.
Top product features:
- High torque zero-backlash coupling
- Keyed clamp type 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 with more convolutions
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 20mm bores, 8mm x 6mm 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.
