German-Standard Engineering for Extreme Performance

The WSP Series Telescopic Universal Joint represents a full upgrade in mechanical transmission technology. Benchmarked against premium German brands, our joints feature a reinforced riveting structure and high-performance 42CrMo alloy steel. Designed for the most demanding environments, these joints excel in high-speed, large-angle, and extreme temperature applications, providing a “1 set equals 5 sets” service life.

Core Performance Upgrades

• Upgraded 42CrMo Material: The entire joint fork is forged from 42CrMo, offering superior toughness and fatigue resistance compared to standard carbon steel.

• HRC60 Bearing Steel Pins: Our pins are made of premium bearing steel, heat-treated to HRC55-60, while the joint body maintains HRC48-52. This creates a “no-loose-pin” structure for extreme durability.

• Precision Spline Design: Available in single, double, and hexagonal spline configurations, allowing for smooth telescopic extension and reliable torque transmission over variable distances.

• Extreme Environment Ready: Engineered to withstand ultra-high and ultra-low temperatures without compromising structural integrity or transmission efficiency.

• Advanced Surface Protection: Choose from various anti-rust treatments: Nickel plating, Black oxide, Galvanized, Chrome plating, Dacromet, or Zinc-nickel alloy for maximum corrosion resistance.

• Optional Dust Cover (Boot): Protect the joint from dust and debris, significantly extending the maintenance intervals and overall lifespan.
