SRW1810 Bearing Product Overview & Core Advantages
The SRW1810 is a single row deep groove ball bearing designed for high-performance applications requiring precision and reliability. Manufactured entirely from stainless steel (rings, balls, and cage), it offers excellent corrosion resistance. This bearing is engineered to primarily support radial loads with a high limiting speed of 36,000 rpm. Its compact, inch-series design and ABEC1 precision class make it an ideal choice for applications demanding consistent performance and dimensional stability.
SRW1810 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SRW | Series designation for a specific line of stainless steel, deep groove ball bearings. |
| 18 | Bore diameter code (0.3125 inches). |
| 10 | Outside diameter code (0.5 inches). |
| (No Suffix) | Indicates an open (unsealed) bearing construction, requiring external lubrication. |
SRW1810 Bearing Structural Features & Performance Benefits
- All-Stainless-Steel Construction: Provides superior corrosion resistance, making it suitable for harsh environments and ensuring long service life.
- Deep Groove Raceway: Optimized for handling significant radial loads, while also capable of supporting moderate axial loads in both directions.
- High-Speed Capability: The combination of a stainless steel cage, precision-ground components, and MC3 internal clearance enables stable operation at high rotational speeds up to 36,000 rpm.
- Precision Engineering: Manufactured to ABEC1 tolerance class with tight dimensional control on bore, outside diameter, and width for reliable and predictable performance.
- Extended Inner Ring: The inner ring width (0.1875") is greater than the total bearing width, facilitating easier mounting and axial location.
SRW1810 Bearing Typical Application Areas
This bearing is commonly used in:
- Medical and Dental Equipment (e.g., small handpieces, pumps)
- Precision Instruments and Optical Devices
- Food Processing and Packaging Machinery (where corrosion resistance is critical)
- Small Electric Motors and High-Speed Spindles
- Office Automation Equipment
