SMR115 2rs Bearing Product Overview & Core Advantages
The SMR115 2RS is a sealed miniature ball bearing designed for precision applications requiring reliable performance in compact spaces. Constructed entirely from stainless steel for excellent corrosion resistance, this single-row deep groove ball bearing is engineered to handle primarily radial loads. Its key advantages include a compact design with a 5mm bore, robust nitrile rubber seals (2RS) for effective contamination exclusion, and suitability for a wide operating temperature range. It is an ideal solution for applications demanding high reliability, low maintenance, and consistent operation.
SMR115 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SMR115 | Standard designation for a miniature bearing series with a 5mm bore and 11mm outside diameter. |
| 2RS | Indicates the bearing is fitted with contact seals on both sides, made of Nitrile Rubber. This provides superior protection against dust and moisture ingress. |
SMR115 2rs Bearing Structural Features & Performance Benefits
- Robust Construction & Corrosion Resistance: The all-stainless-steel construction (rings, balls, cage) ensures high corrosion resistance and durability, making it suitable for harsh environments.
- Effective Sealing: The 2RS bilateral contact seals effectively retain lubricant and exclude contaminants, significantly extending bearing service life and enabling maintenance-free operation in many applications.
- Precision Performance: Manufactured to ABEC1 tolerance class, this bearing offers reliable and consistent running accuracy for smooth operation.
- Optimized Internal Design: With 8 precision balls and a specified MC3 radial internal clearance (0.002mm to 0.013mm), the bearing is optimized for a wide range of operating conditions, balancing low noise and thermal expansion considerations.
