1005 Bearing Product Overview & Core Advantages
The 1005 is a metric single-direction thrust ball bearing engineered for applications requiring high-precision axial load support. This precision bearing is characterized by its ability to accommodate high axial dynamic load ratings while maintaining a compact cross-section. Manufactured from 52100 Chrome Steel for both rings and balls, it ensures excellent durability and performance in demanding environments. Its open design necessitates lubrication but allows for high operational speeds, making it a reliable component for high-speed thrust applications.
1005 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Interpretation |
|---|---|
| 1005 | Standard model number for a metric series single-direction thrust ball bearing. |
| Open (Seal Type) | No integral seals or shields. This design allows for higher limiting speeds and requires external lubrication for optimal performance. |
1005 Bearing Structural Features & Performance Benefits
- High Axial Load Capacity: The bearing's geometry and material construction are optimized to support significant axial static load ratings of 5325 lbf and axial dynamic load ratings of 995 lbf, providing robust performance in thrust applications.
- High-Speed Capability: The open design, combined with a chrome steel cage, contributes to a high limiting speed of 7,280 rpm, making it suitable for high-speed machinery.
- Precision Engineering: Features tight dimensional tolerances on the bore diameter and outside diameter, ensuring precise fit and reliable operation in high-accuracy assemblies.
- Compact and Lightweight: With a bearing width of just 14 mm and a weight of 0.09 kg, it offers a space-saving solution without compromising on load capacity.
1005 Bearing Typical Application Areas
This bearing is ideally suited for applications where high axial loads are present and space is constrained. Key industries and equipment include:
- Machine Tool Components (e.g., lead screws)
- Automotive Steering Systems
- Industrial Pumps and Compressors
- Precision Gearboxes
- Agricultural Machinery
