Compact and Precise: WJ-WJS Ball-Type Universal Joint Couplings

Our WJ and WJS series ball-type universal joints utilize a precision spherical component as the central hinge point, replacing traditional cross shafts. This design allows for a more compact structure and high flexibility, making it the ideal choice for small-scale transmission systems requiring reliable synchronous rotation between driving and driven shafts.

Core Product Advantages

• Premium Alloy Steel (42CrMo): Crafted from high-grade 42CrMo/Bearing Steel to ensure uniform hardness and superior wear resistance.

• Ultra-Compact Design: Features a simplified structure and small volume, perfect for space-constrained mechanical assemblies.

• H7 Precision Ground Bore: Internal bores are ground to H7 accuracy, providing a tight fit, low clearance, and reduced noise during high-speed operation.

• Wide Angular Range: Capable of handling shaft angles $\beta < 40^\circ$ while maintaining synchronized power transmission.

• Durable Blackening Surface: The blackened finish increases surface hardness and corrosion resistance, reducing friction and extending the joint’s service life.

• Source Factory Customization: We offer full OEM/ODM support, including custom bore configurations and specialized dimensions to meet your specific project needs.
