1001 Bearing Product Overview & Core Advantages
The 1001 is a metric thrust ball bearing engineered for high-precision axial load applications. This open-type bearing is designed to accommodate unidirectional thrust loads with exceptional reliability. Manufactured from 52100 Chrome Steel, it delivers robust performance in demanding environments while maintaining compact dimensions (12mm bore, 28mm OD). Its precise tolerances and compliance with ROHS/REACH standards make it ideal for applications requiring high axial rigidity and consistent operation under pure thrust conditions.

1001 Bearing Structural Features & Performance Benefits
Axial Load Specialization: The thrust-specific design provides optimal axial load capacity with dynamic rating of 435 lbf and static rating of 2080 lbf, ensuring reliable performance in pure thrust applications.
Precision Engineering: Tight dimensional tolerances (bore: -0.008mm to 0, width: +0.02mm to -0.25mm) guarantee precise fitment and consistent operation in high-accuracy assemblies.
High-Speed Capability: With a limiting speed of 11,740 rpm, this bearing supports high-speed thrust applications when properly lubricated and maintained.
Material Excellence: 52100 Chrome Steel construction for both rings and balls ensures exceptional durability and wear resistance across the operating temperature range of -30° to 110°C.
