SMR105 2rs Bearing Product Overview & Core Advantages
The SMR105 2RS is a sealed miniature ball bearing designed for precision applications requiring reliable performance in compact spaces. This single row deep groove ball bearing excels at handling radial loads while offering moderate axial load capacity. Constructed entirely from stainless steel with nitrile rubber seals (2RS), it provides excellent corrosion resistance and effective contamination protection. Its ABEC1 precision class ensures consistent operation, making it ideal for applications demanding high reliability and smooth rotational characteristics.
SMR105 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| SMR105 | Miniature bearing series with 5mm bore diameter | Compact design for space-constrained applications |
| 2RS | Double rubber contact seals on both sides | Superior contamination exclusion and grease retention |
SMR105 2rs Bearing Structural Features & Performance Benefits
Deep Groove Geometry: The optimized raceway design enables efficient radial load distribution across all eight precision balls, reducing stress concentrations and extending service life.
Stainless Steel Construction: All critical components (rings, balls, cage) are manufactured from stainless steel, providing excellent corrosion resistance and maintaining dimensional stability across the operating temperature range of -30°C to 110°C.
Double Rubber Seal Protection: The 2RS seals effectively exclude contaminants while retaining lubrication, making the bearing suitable for applications where maintenance access is limited or environmental conditions are challenging.
Optimized Internal Clearance: With MC3 radial clearance (0.002mm to 0.013mm), the bearing accommodates thermal expansion while maintaining precise operation, particularly important in applications with varying thermal conditions.
