1105 Bearing Product Overview & Core Advantages
The 1105 thrust ball bearing is a metric single-direction thrust bearing engineered for applications requiring high-precision axial load support. Its primary function is to accommodate thrust loads in one direction while facilitating high-speed operation. Manufactured from 52100 Chrome Steel, this bearing offers excellent durability and is characterized by its compact design, making it ideal for assemblies with strict space constraints. Its high axial static load rating ensures reliable performance in demanding conditions.

1105 Bearing Structural Features & Performance Benefits
- High-Precision Axial Load Capacity: Designed specifically to handle significant thrust loads, with a high axial static load rating of 5325 lbf, providing robust support against axial forces.
- Optimized for High-Speed Operation: The chrome steel cage and precision-ground components contribute to a high limiting speed of 6,960 rpm, enabling smooth performance in rapid rotation applications.
- Rigorous Dimensional Tolerances: Features tight bore and outside diameter tolerances, ensuring precise fit and stable operation within the assembly, which is critical for high-precision machinery.
- Material Integrity: Constructed entirely from 52100 Chrome Steel, including rings, balls, and cage, for consistent hardness, wear resistance, and long service life.
1105 Bearing Typical Application Areas
This thrust ball bearing is suited for a wide range of industrial and precision equipment, including:
- Machine Tool Components: Used in spindles and lead screws for precise axial positioning.
- Automotive Transmissions: Supports thrust loads in gear assemblies.
- Industrial Pumps and Compressors: Manages axial forces in rotating shafts.
- Precision Instruments and Medical Devices: Provides accurate axial load support in compact, high-reliability systems.
