The needle roller bearing process focuses on “precision forming + performance enhancement,” meeting the high-load requirements of compact spaces. High-carbon chromium bearing steel is carefully selected and homogenized to ensure high wear and fatigue resistance. The needle rollers are formed in a single step by cold heading, followed by precision centerless grinding to achieve micron-level diameter tolerances. Surface phosphate treatment further reduces friction loss. The ring grooves are CNC profile-ground, achieving inner and outer diameter tolerances within IT5, ensuring a precise fit with the needle rollers.
Key components undergo overall quenching and tempering, coupled with cryogenic treatment to stabilize the metallographic structure and prevent dimensional deformation during use. Assembly is completed in a Class 1000 cleanroom, with precise clearance control ensuring smooth rotation. The finished product undergoes dimensional accuracy, rotational noise, and dynamic life testing. Ultimately, it is suitable for compact transmission applications such as automotive transmissions, precision motors, and hydraulic pumps, achieving the technological value of “small size, high load capacity.”
