Clamp Bellows Cplg, Bores 1.250"x20mm, OD 2.250", L 3.200", Aluminum
This Ruland Clamp Bellows Coupling is a high-performance, zero-backlash solution for responsive systems in industries such as semiconductor, solar, test and measurement, and printing equipment. Its lightweight, low-inertia design accommodates all types of misalignment and provides high torque and torsional stiffness capabilities. With a balanced design for reduced vibration at high speeds of up to 10,000 RPM, this coupling is ideal for applications requiring precise movement and positioning. Its compact size and metric hardware make it a versatile choice for a wide range of applications, including robotic arms, motion control systems, and precision machinery.
Top product features:
- High torque zero-backlash coupling
- Creates a lightweight low inertia coupling
- Accommodates all types of misalignment
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 clamp type bellows coupling consists of two anodized aluminum hubs and a stainless steel bellows creating a lightweight low inertia coupling. It has 1.250" x 20mm bores, 2.250" (57.2mm) OD, and 3.200" (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.
