HY57 Universal Joint Cross Bearing

The HY57 Universal Joint Cross Bearing is a core precision component of universal joint couplings and propeller shafts, engineered to transmit rotational torque between non-collinear shafts while accommodating angular misalignment.

Crafted from high-strength alloy steel with precision forging and heat treatment, this cross bearing delivers exceptional hardness, wear resistance, and fatigue strength, ensuring stable performance under high dynamic loads and extending service life.

Its four cylindrical needle roller bearing assemblies are equipped with yellow sealing rings, which effectively prevent lubricant leakage and block dust, moisture, and debris from entering the bearing cavity. The central grease fitting allows for convenient lubrication replenishment, reducing friction and wear to maintain smooth operation. The precision-machined cross body ensures accurate alignment with the yoke, minimizing backlash and vibration during torque transmission.

Manufactured to strict dimensional tolerances, the HY57 ensures excellent dynamic balance, making it compatible with a wide range of universal joint couplings and propeller shafts. Its robust construction and reliable sealing design make it suitable for use in diverse operating environments, from automotive and commercial vehicles to industrial machinery and agricultural equipment.

This universal joint cross bearing is a critical replacement part for maintaining the performance and reliability of power transmission systems. It is engineered to match standard interface specifications, ensuring seamless installation and optimal torque transmission efficiency.
