Advanced Uniform Kinematics: Double Structure Pin & Block Universal Gimbal Cardan Shaft

The Double Structure Universal Gimbal Cardan Drive Shaft Coupling is engineered to provide continuous, high-efficiency power transmission across severely misaligned industrial, agricultural, and construction equipment layouts. Traditional single-joint cardan setups suffer from speed fluctuations (non-uniform rotation) when operating through a deflection angle. The double structure universal joint resolves this mechanical bottleneck by utilizing two pin-and-block joints mounted back-to-back. The second joint actively cancels out the speed fluctuations generated by the first, ensuring true uniform velocity transfer while accommodating large parallel shaft offsets and compound angular misalignments. It is highly effective for steering linkages, farm equipment, heavy construction works, energy systems, and mining machinery.

As shown in our technical specifications profile in universal joint coupling, this premium metric assembly is forged from high-grade 42CrMo alloy steel (42CRMO) and heat-treated to an impressive structural hardness of 50HRC. This double cardan assembly supports an exceptional operating angle of 45 degrees, a 20mm bore diameter, and a length of 400 mm as a standard footprint, while maintaining a broad performance envelope to handle high-torque mechanical loads.
