6900 Bearing Product Overview & Core Advantages
The 6900 is a metric single row deep groove ball bearing designed for exceptional performance in compact spaces. Engineered with precision ABEC-1 tolerances, this bearing delivers reliable operation and high rotational accuracy. Its fundamental design enables it to efficiently support radial loads while accommodating moderate axial loads in both directions. The open design allows for versatile lubrication options, making it suitable for a wide range of industrial applications demanding high-speed capability up to 37,000 rpm and consistent performance.
6900 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6900 | Standard designation for a single row deep groove ball bearing with a 10mm bore, 22mm OD, and 6mm width. |
| Open (Seal Type) | No integral seals or shields. Provides maximum speed capability and allows for custom lubrication schemes. |
| C0 (Radial Internal Clearance) | Standard normal clearance group, suitable for most common operating conditions. |
| ABEC-1 | Defines the precision tolerance class, ensuring consistent running accuracy for general applications. |
6900 Bearing Structural Features & Performance Benefits
- Optimized Load Capacity: The deep groove raceway and high-quality chrome steel construction provide a dynamic load rating of 608 lbf and a static load rating of 286 lbf, ensuring durability under significant radial loads.
- High-Speed Performance: The lightweight, corrosion-resistant stainless steel cage maintains ball alignment and stability, contributing to the high limiting speed of 37,000 rpm.
- Precision Engineering: Manufactured to ABEC-1 precision standards with tight dimensional tolerances for reduced vibration and smooth operation.
- Robust Material Selection: Rings and balls made from chrome steel (GCr15) offer high hardness and wear resistance, while the stainless steel cage provides excellent corrosion resistance.
- Standard Internal Clearance: The C0 radial internal clearance (0.003mm to 0.018mm) is ideal for most operating conditions, providing a balance between fit and thermal expansion.
6900 Bearing Typical Application Areas
This versatile ball bearing is widely used in applications requiring compact size, high speed, and reliable performance. Key sectors include:
- Electric Motors: Small to medium-sized motors for appliances, power tools, and fans.
- Precision Instruments: Medical devices, optical equipment, and measuring instruments.
- Office Automation: Printers, scanners, and copiers.
- Automotive Components: Auxiliary units, pumps, and alternators.
