S627 2rs Bearing Product Overview & Core Advantages
The S627 2RS is a single row deep groove ball bearing designed for precision applications requiring reliable performance. Constructed entirely from stainless steel with integral rubber seals (2RS), this bearing offers excellent corrosion resistance and effective protection against contaminants. Its compact design and ABEC1 precision class make it ideal for applications demanding smooth operation and high reliability under radial loads.
S627 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S627 | Basic bearing designation indicating a metric, single row deep groove ball bearing with a 7mm bore, 22mm OD, and 7mm width. |
| 2RS | Bearing is equipped with contact rubber seals on both sides, providing superior protection against dust and moisture ingress. |
S627 2rs Bearing Structural Features & Performance Benefits
- Corrosion Resistance: The all-stainless steel construction (rings, balls, cage) ensures excellent performance in corrosive or washdown environments.
- Effective Sealing: The 2RS rubber seals effectively retain lubrication and exclude contaminants, extending bearing service life and reducing maintenance needs.
- Precision Performance: Manufactured to ABEC1 tolerance class with optimized internal geometry for smooth, low-noise, and low-vibration operation.
- Radial Load Capacity: The deep groove raceway design is optimized to handle significant radial dynamic loads (566 lbf / 2.52 kN).
- Standard Internal Clearance: Features C3 radial internal clearance (0.002mm to 0.013mm), suitable for applications with moderate thermal expansion or interference fits.
S627 2rs Bearing Typical Application Areas
- Food processing and packaging machinery
- Medical and dental equipment
