Keyed Clamp Bellows Cplg, Bores 1.250"x0.625", OD 2.250", L 3.200", Alum

This high-performance bellows coupling is designed for responsive systems in industries such as semiconductor, solar, and test and measurement equipment. Its lightweight and 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 capabilities, accommodating all types of misalignment. Suitable for applications requiring high accuracy and precision, this coupling is ideal for printing equipment and other applications where responsiveness and reliability are critical. Its durable construction and compliance with RoHS and REACH standards ensure long-lasting performance.

Top product features:

  • High torque zero-backlash capability
  • Provides a lightweight low inertia design
  • Accommodates all types of misalignment due to flexible bellows with rigid torsional stiffness

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 1.250" x 0.625" bores, 1/4" x 3/16" keyways, 2.250" OD, and 3.200" 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.
