SR1810 Bearing Product Overview & Core Advantages
The SR1810 is a single row deep groove ball bearing designed for reliable performance in a wide range of industrial applications. Manufactured entirely from stainless steel, it offers excellent corrosion resistance, making it suitable for demanding environments. This bearing is engineered to handle primarily radial loads and is characterized by its compact inch dimensions (0.3125" bore x 0.5" OD), facilitating integration into space-constrained designs. Its ABEC1 precision class ensures consistent and smooth operation, providing a cost-effective solution for general-purpose machinery requiring dependable rotation and long service life.
SR1810 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SR | Indicates a Single Row deep groove ball bearing construction. |
| 1810 | Specifies the bearing's size series and bore diameter in inches. |
| Open (Seal Type) | The bearing is supplied without seals or shields, allowing for easy re-lubrication and customization but requiring a clean operating environment or external sealing. |
| MC3 (Internal Clearance) | Defines a greater than normal radial internal clearance (0.00008" to 0.0005"), suitable for applications with significant thermal expansion or where interference fits are used. |
SR1810 Bearing Structural Features & Performance Benefits
- All-Stainless Steel Construction: The rings, balls, and cage are made from stainless steel, providing superior corrosion resistance and enabling operation in harsh or washdown environments within a temperature range of -86 to 230 °F.
- Optimized Deep Groove Raceway: The deep groove geometry is engineered for efficient radial load support, contributing to the dynamic load rating of 94 lbf and ensuring stable rotation.
- Stainless Steel Cage: The cage, manufactured from the same corrosion-resistant material, ensures uniform ball spacing and smooth operation at the bearing's limiting speed of 36,000 rpm.
- Standard Internal Clearance (MC3): The specified radial internal clearance accommodates thermal effects and specific mounting conditions, preventing preload and ensuring optimal performance.
- Compliance & Versatility: The bearing is ROHS and REACH compliant and is supplied unlubricated, offering flexibility for the user to apply the most suitable lubricant for their specific application.
