Engineered Precision U Joint Couplings for Superior Angular Power Transmission

In the complex world of mechanical power transmission, finding reliable components that can efficiently connect misaligned shafts is paramount. This is where our professional-grade U joint couplings come into play. Apexcoupling, a leading manufacturer based in Guangdong, China, specializes in producing high-precision U joint couplings designed to meet the rigorous demands of various industrial applications. Our WS and WSD series U joint couplings, manufactured according to the JB/T5901 standard, represent the pinnacle of durability, flexibility, and performance. These robust U joint couplings are engineered to transmit torque smoothly between shafts positioned at significant angles, ensuring minimal power loss and maximum operational efficiency.

The core of our U joint couplings is their construction from premium 42CrMo alloy steel, which undergoes precise heat treatment to achieve an exceptional hardness range of HRC 48-52. This material choice, combined with bearing pins hardened to HRC 56-58, ensures that our U joint couplings can handle high torque loads—from 11.2 N.m to 1120 N.m—while resisting wear and fatigue over extended periods. A key feature of these U joint couplings is their impressive angular compensation capability. Each joint within our U joint couplings allows for a maximum articulation of 45 degrees, with a recommended continuous working angle of 30 degrees or less to ensure optimal longevity and performance. This flexibility makes our U joint couplings ideal for applications where shaft alignment is not perfect or where the angle needs to adjust during operation. We offer two primary configurations of these U joint couplings: the WS model, which features a double-joint design for greater flexibility, and the WSD model, a single-joint version for simpler applications.

Advanced Design and Performance Features of Our U Joint Couplings

Our commitment to quality is evident in every detail of our U joint couplings. The bores are machined to a precise H7 tolerance, guaranteeing a perfect fit on the shaft and minimizing radial play. This precision machining results in U joint couplings with very small internal clearances, which translates to smoother operation, reduced vibration, and lower noise levels—critical factors in precision machinery. We provide two internal bearing options for our U joint couplings: a durable pin-and-block structure rated for speeds up to 1000 RPM, and a high-performance needle bearing version capable of reaching 4000 RPM. For optimal service life, we recommend operating these U joint couplings at or below 50% of their maximum rated speed. The connection hubs on our U joint couplings are supplied with standard keyways and set screws for secure mounting, but we offer full customization, including hexagonal or square bores, to meet any OEM requirement. Furthermore, these U joint couplings can be finished with various surface treatments—including blackening, chrome or nickel plating, and sandblasting—to enhance corrosion resistance and suit specific environmental conditions.
