Product Description
WX/WXD Small Cross-Axis Universal Joint Coupling – Single/Double Joint, OEM Customizable
Factory direct | 11.2–1120 N·m torque | 45° angle per joint | H7 bore | Keyway, hexagon, square hole options | OEM/ODM/OBM
The Apexcoupling WX/WXD series is a small cross-axis universal joint coupling designed for precision power transmission between two shafts on the same plane with angular misalignment up to 45°. Available in single joint (WXD) and double joint (WX) configurations, this coupling delivers nominal torque from 11.2 to 1120 N·m with high transmission efficiency. Built to JB/T5901-1991 standards, it features H7 finished bore tolerance and supports custom hole types including keyway, hexagon, and square holes.
✅ The angle between the two shafts can vary within a limited range according to operational needs.

FAQ
Q: What is the difference between WX and WXD?
A: WXD is a single universal joint – for angular misalignment only. WX is a double universal joint – allows both angular misalignment and parallel offset, providing smoother motion.
Q: What is the maximum operating angle?
A: Each joint can operate up to 45° limit angle. For continuous operation with bearings and fixed pins, we recommend ≤30°.
Q: What torque range is available?
A: The standard series covers 11.2 – 1120 N·m. Custom higher torque is available on request.
Q: What speed ratings are available?
A: Pin/block design – up to 1000 rpm. Needle bearing design – up to 4000 rpm. For speeds above 1000 rpm, needle bearing is recommended.
Q: What bore types can I get?
A: We offer keyway, hexagon hole, square hole, and plain hole. Custom bore types available on request.
Q: What is the bore tolerance?
A: Standard finished bore tolerance is H7 for precision shaft fit.
Q: What materials are available?
A: Standard is 42CrMo alloy steel. We also offer 304 stainless steel for corrosion-resistant applications.
Q: What surface finishes are available?
A: Standard is black oxide. We also offer nickel plated, galvanized, and polished finishes.
Q: Can the angle change during operation?
A: Yes. The angle between the two shafts is allowed to change within a limited range according to working needs.
