SF626 2rs Bearing Product Overview & Core Advantages
The SF626 2RS is a single row deep groove ball bearing designed for exceptional performance in demanding applications. Engineered with stainless steel construction throughout its rings, balls, and cage, it offers superior corrosion resistance. Its key advantage lies in its sealed design (2RS), which effectively retains lubricant and excludes contaminants, ensuring long-term reliability and reduced maintenance. This bearing is optimized to handle primarily radial loads and is suitable for a wide operating temperature range, making it a versatile and durable choice for precision machinery.
SF626 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SF626 | Basic bearing designation indicating a flanged metric series bearing with a 6mm bore. |
| 2RS | Contact Rubber Seals on both sides. This provides superior protection against contamination and grease leakage compared to non-contact shields. |
SF626 2rs Bearing Structural Features & Performance Benefits
- Robust Sealed Construction: The double-sided nitrile rubber seals (2RS) ensure excellent contamination exclusion, making the bearing ideal for dusty or humid environments and contributing to its long service life with minimal maintenance.
- High Precision & Smooth Operation: Manufactured to ABEC1 tolerance class with a stainless steel cage, this bearing provides consistent, low-noise, and low-vibration performance, essential for sensitive applications.
- Corrosion Resistance: The all-stainless steel construction (rings, balls, cage) provides excellent resistance to rust and corrosion, suitable for washdown environments or applications exposed to mild chemicals.
- Flange Design: The integrated flange (22mm outer diameter) simplifies mounting and positioning, providing secure axial location within a housing and saving on assembly costs.
- Optimized Load Capacity: With a radial dynamic load rating of 402 lbf and a static rating of 145 lbf, it reliably handles significant radial forces for its compact bearing dimensions (6x19x6mm).
