1 Exquisite Production: Ball bearing has advanced technology, glossy and flat bearing appearance, waterproof and dustproof, not easy to rust, and long service life. 2 Mute Effect: Ball bearing is well made and works in coordination with the machine, which greatly improves the operating efficiency of the machine and makes the bearing noise less. 3 High Speed Operation: Steel ball bearings rotate with minimal frictional resistance, so as to obtain high accuracy glossy motion. 4 High Hardness: Self aligning ball bearing uses steel, which has high hardness, good wear resistance and contact fatigue strength, while the core also maintains good toughness and can carry high impact loads. 5 Wide Application: Ball bearing is widely used in gearboxes, instrumentation, motors, household appliances, internal combustion engines, transportation vehicles, agricultural machinery, construction machinery, engineering machinery, roller skates, yo yos, etc.
