This clamp type bellows coupling consists of two anodized aluminum hubs and a stainless steel bellows creating a lightweight low inertia coupling. 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.875", OD 2.250", L 3.
It is made from stainless steel for corrosion resistance.These components are manufactured to tight tolerances using proprietary processes that ensure smooth operation and high misalignment accommodation up to 90°, which is a significant improvement over commodity style double universal joints.
