This bearing is made of selected high carbon chromium steel, strengthened by precision heat treatment process, and has both high hardness and strong wear resistance. It can withstand heavy loads and high temperature conditions for a long time, greatly reducing wear and tear, and reducing equipment downtime frequency. Accurate control of inner and outer diameters, width, and ball diameter tolerances, coupled with precise matching of ball bearings, effectively reduces operating friction, vibration, and noise, improves equipment smoothness, while reducing energy consumption and extending overall service life. Widely covered in size, compatible with mainstream equipment models, suitable for various fields such as automotive transmission, industrial motors, agricultural machinery, engineering machinery, etc. Standardized design facilitates installation and replacement. The entire process strictly controls dimensional accuracy, surface smoothness, and hardness testing, ensuring reliable quality. It is the preferred choice for the core transmission components of the equipment.
