SFRW3 Bearing Product Overview & Core Advantages
The inch-series single row ball bearing is a precision-engineered component designed for demanding radial load applications. Featuring an extended inner ring for simplified mounting and positioning, this bearing delivers reliable performance in compact spaces. Manufactured entirely from stainless steel with an open design, it offers excellent corrosion resistance and requires lubrication for optimal operation. Its ABEC1 tolerance class ensures consistent quality and smooth running, making it ideal for applications where precision and reliability are critical.
SFRW3 Bearing Model Code Explained, Specifications & Naming Convention
| Feature | Designation | Technical Significance |
|---|---|---|
| Construction | Single Row | Compact design optimized for radial loads |
| Seal Type | Open | Requires external sealing; allows for custom lubrication selection |
| Inner Ring | Extended | Facilitates easier mounting and axial positioning |
| Clearance | MC3 | Standard radial internal clearance for general applications |
SFRW3 Bearing Structural Features & Performance Benefits
This bearing's performance is defined by its robust construction. The single row design with 7 precision balls provides stable support for radial dynamic loads up to 224 lbf. The all-stainless steel construction (rings, balls, and cage) ensures superior corrosion resistance and dimensional stability across a wide temperature range from -86 to 230 °F. The optimized ball diameter of 0.0937" and quantity contribute to smooth operation and load distribution. With a limiting speed of 99,000 rpm, it delivers reliable high-speed performance for demanding applications. The MC3 radial clearance provides optimal running performance under normal operating conditions.
