Product Description
Angular Contact Ball Bearings: Core Features & Applications
Core Features
Capable of simultaneously bearing radial loads and unidirectional axial loads. A larger contact angle results in stronger axial load capacity. Pair installation allows for bidirectional axial load bearing and axial positioning.
Capable of simultaneously bearing radial loads and unidirectional axial loads. A larger contact angle results in stronger axial load capacity. Pair installation allows for bidirectional axial load bearing and axial positioning.
The raceway and steel balls have point contact, resulting in high limiting speeds, suitable for high-speed, precision applications. Strict preload control is required; preload improves rigidity and suppresses vibration, making it suitable for high-precision rotation.
Compact structure, available in single-row, double-row, and four-point contact types. Cylindrical bores are commonly used, but tapered bores are also available to suit different installation and interference fit requirements.
High requirements for coaxiality, installation accuracy, and bearing housing rigidity. Angular deviations or insufficient rigidity can easily lead to uneven loading, excessive temperature rise, and premature failure.
Lubrication options include grease lubrication (low to medium speeds) or oil lubrication (high speeds/high temperatures). Sealing/dustproof structures are available to suit different cleaning and temperature requirements.
Typical Application Scenarios
Machine Tool Industry – Spindle units, lead screw supports, high-speed grinding machines/machining centers; core compatibility reasons include high speed and precision, high rigidity, ability to withstand radial + axial composite loads, and high positioning accuracy after paired preload.
Motor Industry – High-speed servo motors, spindle motors, generator bearings; core compatibility reasons include high speed and low vibration, ability to withstand axial electromagnetic thrust, and long-term stable operation.
Automotive Industry – High-speed transmission shafts, turbochargers, steering systems; core compatibility reasons include high-speed operating conditions, compact space, and tolerance to temperature fluctuations.
General Machinery – Compressors, water pumps, and improved equipment operating accuracy and stability.
Aerospace – Aero-engine accessories, helicopter rotor systems, precision instruments;and meeting reliability requirements under extreme operating conditions.
