| Load Direction | Thrust | Specifically designed to handle axial loads only. |
1010 Bearing Structural Features & Performance Benefits
- High Axial Load Capacity: The bearing's geometry and use of chrome steel components provide a high axial dynamic load rating of 1665 lbf and an exceptional axial static load rating of 11090 lbf, ensuring robust performance under significant thrust forces.
- Precision Engineering: Tight dimensional tolerances on the bore diameter (50 mm), outside diameter (74 mm), and width (18 mm) guarantee precise fit and alignment, contributing to smooth operation and extended service life.
- Optimized for Speed: The open design and chrome steel cage contribute to a high limiting speed of 4,630 rpm, making it suitable for applications requiring rapid rotation.
- Material Integrity: Constructed entirely from 52100 Chrome Steel for the rings and balls, this bearing offers high hardness, wear resistance, and consistent performance across its specified temperature range of -30° to 110 °C.
1010 Bearing Typical Application Areas
This thrust ball bearing is commonly specified in:
- Automotive Systems: Thrust applications in transmissions and steering mechanisms.
- Industrial Machinery: Machine tool tables, screw assemblies, and jacks where high axial loads are present.
- Pumps and Compressors: To accommodate thrust loads in rotating assemblies.
- Precision Equipment: Applications requiring reliable, single-direction axial support with compact bearing dimensions.
