Keyed Clamp Bellows Cplg, Bores 20mmx0.750", OD 1.625", L 2.000", Alum
This high-performance keyed clamp bellows coupling is designed for demanding applications in semiconductor, solar, test and measurement, and printing equipment. Its lightweight, low-inertia design and four convolution bellows provide high torque and torsional stiffness capabilities, accommodating all types of misalignment while remaining rigid under torsional loads. With a balanced design for reduced vibration at high speeds of up to 10,000 RPM, this coupling is ideal for responsive systems requiring precise motion control. Its RoHS and REACH compliance ensures environmental responsibility, making it a reliable choice for a wide range of industrial applications.
Top product features:
- High torque zero-backlash coupling
- Keyed clamp design allows for increased torque capacity and prevents 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 20mm x 0.750" bores, 6mm x 3/16" keyways, 1.625" (41.3mm) OD, and 2.000" (50.8mm) 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.
