SF6905 Bearing Product Overview & Core Advantages
The SF6905 is a metric single row flanged ball bearing engineered for compact radial load applications requiring high precision and reliable performance. Constructed with stainless steel rings and cage alongside chrome steel balls, it offers excellent corrosion resistance and durability. Its integral flange facilitates secure mounting and precise axial location, making it an ideal choice for applications demanding high rigidity and space-saving design. The bearing operates effectively within a temperature range of -30° to 110°C and conforms to ABEC-1 precision tolerances.
SF6905 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SF6905 | Basic model number denoting a flanged, single row deep groove ball bearing with a 25mm bore. |
| Open (Seal Type) | The bearing is unsealed, allowing for custom lubrication strategies but requiring a clean operating environment. |
| C0 (Radial Internal Clearance) | Specifies a normal internal clearance group (0.002mm to 0.013mm), suitable for most general applications. |
| ABEC-1 | Indicates standard precision tolerance class, ensuring consistent and reliable performance. |
SF6905 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row design with a flanged outer ring provides stable support and high resistance to deflection under radial loads. With a dynamic load rating of 1418 lbf and a static load rating of 921 lbf, it handles significant operational stresses.
- Optimized Internal Geometry: Featuring 13 high-grade chrome steel balls with a diameter of 4.762 mm, the bearing ensures smooth rotation and efficient load distribution.
- Corrosion Resistance: The use of stainless steel for the rings, cage, and shield makes the SF6905 suitable for harsh environments where moisture or chemicals are present.
- Precision Performance: Manufactured to ABEC-1 tolerance standards, this bearing guarantees running accuracy and low vibration, contributing to the overall precision of the assembly.
SF6905 Bearing Typical Application Areas
The SF6905 flanged ball bearing is commonly specified in:
- Small Electric Motors and Precision Gearboxes for accurate shaft positioning.
- Medical Devices and Laboratory Equipment requiring corrosion-resistant components.
- Office Automation Equipment such as printers and scanners.
- Food Processing Machinery and other applications where washdowns are frequent.
- Various Instrumentation and Control Systems demanding reliable, compact bearing solutions.
