SF682x 2rs Bearing Product Overview & Core Advantages
The SF682x 2rs is a miniature sealed ball bearing designed for precision applications requiring compact dimensions and reliable performance. This single row deep groove ball bearing features integral rubber seals (2RS) for effective contamination protection. Engineered with stainless steel rings, cage, and balls, it offers excellent corrosion resistance. Its compact design (2.5mm bore) makes it ideal for space-constrained applications while maintaining the ability to handle radial loads efficiently. The bearing comes pre-lubricated and is suitable for moderate speed operations.
SF682x 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Advantage |
|---|---|---|
| 68 | Series designation for miniature bearings | Compact size series for small mechanisms |
| 2 | Flange design identifier | Simplifies mounting and positioning |
| RS | Double rubber contact seals | Enhanced contamination protection, retains lubrication |
SF682x 2rs Bearing Structural Features & Performance Benefits
Compact Design Excellence: With a minimal cross-section (2.6mm width) and lightweight construction (0.24g), this bearing provides optimal performance in space-limited applications while maintaining structural integrity.
Superior Sealing Performance: The double rubber contact seals (2RS) effectively prevent the ingress of contaminants and retain lubricant, ensuring extended service life and reduced maintenance requirements in challenging environments.
Corrosion Resistance: Manufactured entirely from stainless steel components (rings, balls, and cage), this bearing offers excellent resistance to corrosion, making it suitable for applications exposed to moisture or aggressive environments.
Precision Performance: Built to ABEC1 tolerance class with controlled radial internal clearance (MC3: 0.002-0.013mm), this bearing ensures smooth operation and consistent performance in precision mechanisms.
