1004 Bearing Product Overview & Core Advantages
The 1004 is a metric thrust ball bearing engineered for applications requiring precise axial load handling. Its primary function is to accommodate thrust loads in a single direction while maintaining a compact cross-section. Manufactured from high-grade 52100 Chrome Steel, this bearing is designed for high-precision assemblies where dimensional stability and reliable performance under axial stress are critical. Its open design necessitates lubrication for optimal operation within its specified temperature range.
1004 Bearing Model Code Explained, Specifications & Naming Convention
The model number 1004 follows a standard designation for metric thrust ball bearings. Its code can be broken down as follows:
- 1004: Standard series code for a metric thrust ball bearing with a 20mm bore diameter.
- Open: Indicates the bearing has no seals or shields, allowing for higher speed capability but requiring a dedicated lubrication system.
1004 Bearing Structural Features & Performance Benefits
The 1004 bearing's performance is defined by its specific construction:
- High Load Capacity: The bearing is designed specifically for axial dynamic load rating of 655 lbf and a high axial static load rating of 3245 lbf, making it suitable for significant thrust forces.
- Precision Engineering: Features tight dimensional tolerances on the bore diameter and outside diameter, ensuring a precise fit and reliable operation in high-accuracy applications.
- Compact & Lightweight: With a width of only 12 mm and a weight of 0.05 kg, it offers a space-saving solution without compromising on strength.
- High-Speed Capability: The open design and Chrome Steel cage material contribute to a limiting speed of 9,190 rpm, suitable for various high-speed mechanisms.
1004 Bearing Typical Application Areas
The 1004 thrust ball bearing is ideally suited for a wide range of industrial and precision equipment, including:
- Automotive steering systems
- Machine tool spindles
- Industrial pumps and compressors
- Precision medical and laboratory equipment
- Automation and robotics assemblies
