Product Description
Rolling Element Precision Bearing Ball Silicon Nitride Ceramic balls G10 for Bearing
►The development history of CAEC silicon nitride ceramic balls:
1986-1990 Exploratory research on ceramic bearings
1991-1995 Preliminary Research on Ceramic Ball Bearings and Ceramic Balls for Bearings
1996-2000 Mass manufacturing technology development of high-speed precision ceramic ball bearings
2000-now Comprehensively improve the level of silicon nitride manufacturing
►Production process of CAEC silicon nitride ceramic balls:
Raw material-granulation-pressing-cold isostatic pressure vessel-air pressure sintering vessel-grinding process-testing and inspection-finished product.
►Quality Assurance System of CAEC silicon nitride ceramic balls:
Use laser confocal microscope and ultrasonic scanning microscope for particle size analysis, impurity content analysis, oxygen and nitrogen content analysis, phase composition analysis.
►Performance testing of CAEC silicon nitride ceramic balls:
Density, hardness, vibration value, crushing load, fracture toughness.
►Product features of CAEC silicon nitride ceramic balls:
I. Excellent friction performance
1. Since the affinity of steel/ceramic matching is lower than that of steel/steel, when the lubricating film is not formed well or lacks lubrication, the lower affinity can effectively reduce the risk of adhesive friction.
2. Due to the high hardness of the ceramic ball, in the case of severe friction, the ceramic ball has good dimensional and shape accuracy retention and repairability to the groove to ensure the bearing running.
II. Small spin-to-roll ratio
Compared with steel bearings, the spin-to-roll ratio of ceramic ball bearings is about 30% lower, indicating that ceramic ball bearings have better contact conditions and lower spin friction.
III. Low temperature rise
Less heat; Small deformation; Low coefficient of friction; Small centrifugal force and gyro torque.
