Core Characteristics: Quenched and hardened surface for wear resistance, core toughness to prevent impact fracture, high-precision flatness ensures uniform load distribution, suitable for axial positioning and thrust requirements of transmission systems.

Structure and Core Characteristics:

Integral quenched structure: 50CrVA material is quenched, with a thrust surface hardness of HRC 58-62, wear-resistant and scratch-resistant, suitable for high-speed and high-axial-force conditions in gearboxes and torque converters.

High-precision thrust surface: Flatness ≤ 0.01 mm, ensuring uniform contact with the bearing cage end face and avoiding early failure caused by localized stress concentration.

Core toughness design: Low-temperature tempering treatment maintains HRC 30-35 toughness in the core, capable of withstanding impact loads, preventing bearing race fracture, suitable for complex working conditions in engineering machinery.

Lubrication System Compatibility: Surface roughness Ra ≤ 0.4 μm, facilitating oil film formation, reducing friction and wear, and extending the life of bearing races and bearings.

Compatible Machines and Application Scenarios

Compatible Equipment: CAT 950, 966, 972 series loaders, 320, 325, 330 series excavators, and some bulldozers and graders’ gearbox output shafts, torque converter turbine shafts, etc.

Core Purpose: Installed between the bearing and the housing, it serves as an axial positioning and thrust bearing, bearing the axial load of the transmission system, preventing axial movement of the bearing, ensuring stable operation of the transmission system, and is suitable for heavy-duty, high-frequency operating conditions such as mining and infrastructure construction.
