SF6900 Bearing Product Overview & Core Advantages
The SF6900 is a flanged miniature ball bearing designed for compact applications requiring reliable radial load support. Its stainless steel construction provides excellent corrosion resistance, while the ABEC-1 precision class ensures consistent performance. The integral flange facilitates easy mounting and precise axial location, making it an ideal choice for space-constrained, high-speed assemblies.
SF6900 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SF6900 | Basic model number for a flanged, single-row deep groove ball bearing. |
| Open (Seal Type) | No integral seals or shields. Requires external sealing in contaminated environments. |
| Stainless Steel | Rings, cage, and shield are made from corrosion-resistant 300 series stainless steel. |
| C0 (Radial Clearance) | Standard radial internal clearance group (0.002mm to 0.013mm). |
SF6900 Bearing Structural Features & Performance Benefits
- Flanged Design: The outer ring flange (25 mm outer diameter) simplifies housing design, prevents bearing creep, and ensures accurate axial positioning.
- High-Speed Capability: With a limiting speed of 27,900 rpm and a stainless steel cage, the bearing is optimized for high rotational accuracy and minimal vibration.
- Corrosion Resistance: Manufactured entirely from stainless steel (rings, cage, shield), it is suitable for applications exposed to moisture or aggressive environments.
- Robust Load Capacity: The single-row deep groove construction effectively handles radial loads (dynamic: 55 lbf, static: 257 lbf) and moderate axial loads in both directions.
SF6900 Bearing Typical Application Areas
- Small Precision Motors and stepper motors
- Medical Devices and dental handpieces
- Office Automation Equipment such as printers and scanners
- Instrumentation and optical encoders
- Radio-Control Models and drones
