Types UC and UI are used in light-duty applcations with large angular misalignment, including instrumentation and positioning systems; UA is used in heavy-duty mission-critical high-torque applications requiring a fail-safe coupling, including servo-controlled valves, mining, and crushing equipment.
Similar to the classic Oldham coupling, but with a torque-transmitting element that’s round in cross-section, rather than rectangular, allowing pivoting similar to a universal joint.
A higher torque, higher stiffness variation without the mechanical fuse protective function. Cylindrical fins overlap, with the axes of the two cylinders intersecting, allowing for pure universal action and smooth angular flexion, while still accommodating a large radial misalignment.
