Hybrid Bearings-Thrust Ball Bearing,ceramic balls+steel rings

Divide into unidirectional thrust ball bearings and bidirectional thrust ball bearings according to the force situation. Unidirectional thrust ball bearings can withstand unidirectional axial loads. Bidirectional thrust ball bearings can withstand bidirectional axial loads, with the shaft ring and shaft fitting. The bearing with a spherical installation surface on the seat ring has centering performance, which can reduce the impact of installation errors. The thrust ball bearing cannot withstand radial loads and has a lower limit speed.
By using ceramic balls, the bearing balls will not expand due to temperature in high temperature environments, greatly increasing the operating temperature of the entire bearing. The temperature of ordinary bearings is around 160 degrees, while the temperature of ceramic balls can reach over 220 degrees.

Hybrid Bearings-Deep groove ball bearing,ceramic balls+steel rings
The most representative rolling bearing, with a wide range of applications, can withstand radial and bidirectional axial loads. Suitable for high-speed rotation and occasions that require low noise and vibration, as well as high temperature, cold, corrosion, magnetic field, non insulation and other fields that cannot be applied to steel bearings. Silicon nitride balls have the characteristics of low density, high hardness, low friction coefficient, wear resistance, self-lubricating, and good rigidity, making them particularly suitable as rolling elements for high-speed, high-precision, and long-life hybrid ceramic ball bearings (with metal inner and outer rings). Generally, the inner and outer rings are made of bearing steel (GCr15) or stainless steel (AISI440C), and ceramic balls can be made of ZrO2, Si3N4, or SiC materials.

Hybrid Bearings-Angular contact bearing,ceramic balls+steel rings
Suitable for high-speed and high-precision rotation, without affecting its accuracy in high temperature, magnetic field, water, etc., and can withstand synthetic loads. The standard contact angles are 15 °, 30 °, and 40 °. The larger the contact angle, the greater the axial load capacity, while the smaller the contact angle, the bearing can withstand radial and unidirectional axial loads. Generally, paired installation is adopted.
Ceramics have advantages such as cold resistance, low stress elasticity, high pressure resistance, poor thermal conductivity, light weight, and low friction coefficient, and can be applied in high-speed spindles and other high-precision equipment; Due to its lack of magnetism, it does not absorb dust and can reduce bearing surface peeling, thereby reducing operating noise. Can be used in demagnetization equipment, precision instruments, and other fields. hybrid bearings angular
