SR1810zz Bearing Product Overview & Core Advantages
The SR1810zz is a precision miniature ball bearing designed for demanding applications requiring high reliability and consistent performance. As a single row deep groove ball bearing, it excels at handling radial loads while also accommodating moderate axial loads in both directions. Manufactured entirely from stainless steel and featuring integral shielded protection, this bearing offers excellent corrosion resistance and durability in a compact, lightweight package, making it ideal for high-precision and high-reliability scenarios.
SR1810zz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SR1810 | Bearing series and size designation (0.3125" bore, 0.5" OD) |
| zz | Indicates the bearing is equipped with shields on both sides (non-contact), providing excellent protection against contamination while maintaining high-speed capability. |
SR1810zz Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: Built to ABEC1 tolerance class with a MC3 radial internal clearance (0.00008" to 0.0005"), ensuring smooth operation and precise rotational accuracy.
- Optimized Load Capacity: The deep groove raceway and 12 stainless steel balls enable efficient handling of both radial dynamic loads (94 lbf) and static loads (45 lbf).
- Corrosion Resistance: Constructed entirely from stainless steel (rings, balls, cage, and shields), providing superior performance in harsh environments and a wide temperature range (-86 to 230 °F).
- Contamination Protection: The zz shields effectively protect the bearing interior from dust and debris, extending service life. Note: Lubrication is required for optimal performance.
SR1810zz Bearing Typical Application Areas
This bearing is ideally suited for:
- Precision Instruments and medical devices
- Small electric motors and gearboxes
- Office automation equipment and small power tools
