Description

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 14mm x 0.375" bores, 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.
