SF605 Bearing Product Overview & Core Advantages
The SF605 is a metric single row deep groove ball bearing engineered for precision radial load applications. Constructed entirely from stainless steel (rings, balls, and cage), it offers excellent corrosion resistance and durability. Its compact design, with a 5 mm bore and 14 mm outside diameter, makes it ideal for space-constrained, high-precision assemblies requiring reliable performance under radial dynamic loads up to 229 lbf. The bearing operates efficiently within a temperature range of -30° to 110 °C and is compliant with ROHS and REACH standards.
SF605 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SF605 | Basic bearing designation indicating size and series. |
| Open (Seal Type) | No integral seals or shields; requires external sealing in contaminated environments. |
| ABEC1 | Standard precision tolerance class suitable for many general applications. |
| MC3 | Specifies a radial internal clearance group of 0.002mm to 0.013mm. |
SF605 Bearing Structural Features & Performance Benefits
- Deep Groove Raceway & Single Row Design: Optimized for high-capacity radial loads, providing smooth operation and low running torque.
- Full Stainless Steel Construction: The rings, 2.381 mm balls, and cage are all made from stainless steel, ensuring superior corrosion resistance and longevity in harsh environments.
- Precision Engineering: Manufactured to ABEC1 tolerances with controlled internal clearance (MC3) for consistent and reliable performance.
- High-Speed Capability: The lightweight, stainless steel cage and optimized geometry contribute to a limiting speed of 36,000 rpm.
- Flanged Outer Ring: The flange (16 mm OD, 1 mm thick) simplifies mounting and positioning within a housing, enhancing assembly accuracy.
SF605 Bearing Typical Application Areas
This miniature ball bearing is widely used in applications demanding compact size, corrosion resistance, and reliable radial load support. Key sectors include:
- Precision Instruments: Optical encoders, measuring devices, and small gauges.
- Small Electric Motors: Used in compact fans, drones, and miniature DC motors.
- Medical Devices: Surgical hand tools, dental drills, and pump mechanisms.
- Office Automation: Printers, scanners, and copiers.
- Food Processing Equipment: Where corrosion resistance and cleanability are paramount.
