This high-torque, zero-backlash bellows coupling is designed for responsive systems in industries such as semiconductor, solar, and test and measurement equipment. Its lightweight, low-inertia design and four-convolution bellows provide higher torque and torsional stiffness capabilities. The addition of keyways increases torque capacity and prevents slipping on the shaft. The coupling's balanced design reduces vibration at high speeds up to 10,000 RPM, making it suitable for applications requiring precise motion control. Its compact size and metric hardware make it a versatile solution for a wide range of applications, from printing to medical devices, where precision and reliability are crucial.
Top product features:
Zero-backlash coupling design allows for high torque transmission with minimal slip.
The addition of keyways increases torque capacity and prevents the coupling from slipping on the shaft when over torqued.
The bellows is able to flex while remaining rigid under torsional loads, accommodating all types of misalignment.
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 1.000" x 25mm bores, 1/4" x 8mm keyways, 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.
