Keyed Clamp Bellows Cplg, Bores 0.625"x10mm, OD 1.313", L 1.688", Alum

Ruland's Keyed Clamp Bellows Couplings are a high-performance solution for responsive systems in semiconductor, solar, test and measurement, and printing equipment. These lightweight, low-inertia couplings feature anodized aluminum hubs and stainless steel bellows, providing increased torque capacity and preventing slipping on the shaft. With a four-convolution bellows design, they offer higher torque and torsional stiffness capabilities than equivalent couplings. Suitable for high-speed applications up to 10,000 RPM, these couplings accommodate all types of misalignment and reduce vibration. Ideal for applications requiring precision and reliability, Ruland's Keyed Clamp Bellows Couplings meet RoHS and REACH compliance standards.

Top product features:

  • It has a zero-backlash design for high torque applications.
  • The addition of keyways allows for increased torque capacity and prevents the coupling from slipping on the shaft when over torqued.
  • The bellows are able to flex while remaining rigid under torsional loads allowing for all types of misalignment to be accommodated.

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 0.625" x 10mm bores, 3/16" x 3mm keyways, 1.313" (33.3mm) OD, and 1.688" (42.9mm) 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.
