SF623 2rs Bearing Product Overview & Core Advantages
The SF623 2RS is a metric single row deep groove ball bearing designed for exceptional reliability in compact applications. This sealed bearing features stainless steel construction throughout, providing excellent corrosion resistance. Its primary advantage lies in its ability to handle radial loads efficiently while offering robust protection against contamination. The integrated nitrile rubber seals (2RS) retain lubrication and exclude pollutants, making it a low-maintenance solution for applications demanding high reliability and long service life within its specified temperature range.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| SF623 | Basic bearing designation indicating a flanged metric bearing with a 3mm bore, 10mm outside diameter, and 4mm width. |
| 2RS | Contact nitrile rubber seals on both sides. This provides superior protection against dust, moisture, and other contaminants compared to non-contact shields, while effectively retaining lubricant. |
SF623 2rs Bearing Structural Features & Performance Benefits
- Deep Groove Raceway & High-Capacity Design: The deep, continuous raceways and complement of 7 precision balls enable reliable handling of radial dynamic loads up to 108 lbf and radial static loads up to 36 lbf.
- Robust Sealing Solution: The 2RS contact seals, made of nitrile rubber, provide an effective barrier, making the bearing suitable for environments where contamination is a concern. This contributes to extended lubricant life and reduced maintenance.
- All-Stainless Steel Construction: The rings, balls, and cage are manufactured from stainless steel, offering excellent resistance to corrosion and making the bearing suitable for applications exposed to moisture or mild chemicals.
- Integrated Flange: The flange (11.5mm outer diameter) simplifies mounting and positioning, providing secure axial location within a housing and reducing assembly complexity and cost.
- Precision Performance: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3 group), ensuring smooth and consistent operation.
SF623 2rs Bearing Typical Application Areas
This bearing is ideally suited for small, precision mechanisms requiring corrosion resistance and reliable sealing. Common applications include:
- Small Precision Motors and stepper motors
- Medical Devices and laboratory equipment
- Office Automation Equipment such as printers and scanners
- Instrumentation and optical devices
- Food Processing Equipment (where corrosion resistance is beneficial)
- Various low-torque, high-speed applications up to 45,000 rpm
