INA Angular Contact Ball Bearings (angular contact ball bearings) are a type of bearing that can withstand both radial and axial loads, and are suitable for high-speed operation scenarios. INA angular contact ball bearings have the following characteristics: INA angular contact ball bearings can withstand radial and axial loads at the same time: This bearing design enables it to withstand loads in both directions, and is suitable for applications that require simultaneous radial and axial forces. High-speed operation capability: Angular contact ball bearings can operate at higher speeds, and are suitable for mechanical equipment that requires high-speed operation. Contact angle affects load-bearing capacity: The size of the contact angle determines the axial load-bearing capacity of the bearing. The larger the contact angle, the stronger the axial load-bearing capacity of the bearing.
Structural features
INA angular contact ball bearings usually have the following structural features:
Inner and outer ring raceway offset: The horizontal axis of the inner and outer ring raceways is offset, allowing the bearing to withstand radial and axial loads at the same time.
Single-row structure: Single-row angular contact ball bearings can only withstand axial loads in one direction and usually need to be installed in pairs to offset additional axial forces.
Cage material: The cage can be made of brass or synthetic resin. Choose the appropriate material according to the working conditions.
INA angular contact ball bearings are widely used in scenarios that require simultaneous radial and axial loads.
High-precision transmission equipment: High-precision transmission equipment such as industrial robots require bearings to withstand large loads while running at high speeds.
High-speed equipment: Suitable for various high-speed mechanical equipment, such as high-speed motors, precision machine tools, etc.
