SFRW1810zz Bearing Product Overview & Core Advantages
The SFRW1810zz is a single row deep groove ball bearing designed for high-performance applications requiring reliable radial load capacity and precision operation. Constructed entirely from stainless steel, it offers excellent corrosion resistance. A key feature is its shielded design (zz), which effectively retains lubricant and excludes contaminants, enhancing service life. With its compact inch dimensions and extended inner ring, this bearing is engineered for applications demanding high reliability and straightforward mounting in compact spaces.
SFRW1810zz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| SFRW | Manufacturer Series/Type | Denotes a specific series of miniature and instrument bearings. |
| 1810 | Size Designation | Specifies the bore (0.3125") and outside diameter dimensions. |
| zz | Shielded on Both Sides | Indicates non-contact shields on both sides for contaminant protection and lubricant retention. Requires initial lubrication. |
SFRW1810zz Bearing Structural Features & Performance Benefits
- Stainless Steel Construction: All components, including rings, balls, cage, and shields, are made from stainless steel, providing superior corrosion resistance and suitability for harsh environments.
- Deep Groove Raceway & Single Row Design: Optimized for carrying significant radial loads and moderate axial loads in both directions.
- Shielded (zz) Protection: The non-contact shields protect against particulate contamination and help retain lubricant, contributing to a longer, more reliable service life without the torque increase associated with contact seals.
- Extended Inner Ring: Facilitates easier mounting and axial location, which is particularly beneficial in precision assemblies.
- ABEC1 Precision: Manufactured to ABEC1 tolerance class, ensuring consistent running accuracy for a wide range of industrial applications.
SFRW1810zz Bearing Typical Application Areas
The SFRW1810zz is ideally suited for applications where compact size, corrosion resistance, and reliable performance are critical. Common uses include:
- Precision Instruments and Medical Devices
- Small Motors and Gearboxes
- Office Automation Equipment (e.g., printers, scanners)
- Radio Control Models and Drones
- Food Processing and Packaging Machinery (where corrosion resistance is key)
