Heavy Duty Double Universal Joints
Our Heavy-Duty Double Universal Joints deliver minimal play, accurate positioning and flexibility under high operating angles. With a maximum combined working angle of 90° (45° per joint), they provide uniform speed-ratio between driving and driven shafts (with parallel output shafts). The standard material for heavy-duty double joints is high-grade alloy steel. They are also available in stainless steel and a variety of other materials and finishes.
