The full complement roller bearing process focuses on “cageless, high-load bearing performance,” utilizing precision machining to ensure stable, densely packed rollers. فولاذ محامل عالي المقاومة للإجهاد is selected for its material, which undergoes vacuum refining to remove impurities, enhancing base material uniformity and impact resistance.

The rollers utilize a process consisting of “cold heading in one step, cylindrical surface grinding, and end face super-lapping.” Diameter tolerances are controlled to IT3, and end face parallelism is ≤0.002 mm, ensuring zero binding when closely packed. The ring raceways are machined using a five-axis CNC grinder, achieving geometric accuracy of IT4 and a roughness of Ra0.2μm, ensuring uniform roller contact.

Key components undergo full quenching and tempering, followed by cryogenic treatment, to prevent dimensional deformation under heavy loads. Dedicated assembly tooling ensures a close 1:1 roller arrangement and precisely controls radial clearance. The finished product undergoes static load and rotational accuracy testing before ultimately being suitable for heavy-load applications such as rolling mills and cranes, fully realizing the value of the “cageless, high-load density” process.
