Value Collection SFRW1-4ZZ Miniature Ball Bearing Flanged

Product Description

The VALUE COLLECTION SFRW1-4ZZ is a miniature flanged ball bearing designed for precision motion applications requiring a compact, durable rolling element component. Built with a stainless steel housing, this single-row bearing features double-shield construction to protect internal components from contamination. It carries an ABEC-5 precision rating, a static load capacity of 23 pounds, and a dynamic load capacity of 70 pounds. The bore diameter measures 0.0781 inches, the outside diameter is 0.25 inches, and the overall width is 0.1406 inches. It is installed by maintenance technicians, mechanical assemblers, and equipment service professionals working on small-scale or precision machinery.

This bearing is suited for use in miniature motors, precision instruments, medical devices, small pumps, and light-duty mechanical assemblies where a compact footprint and reliable radial load performance are required. The flanged design allows for positive axial location within a housing bore, making it appropriate for applications where the bearing must be retained without additional hardware. Its stainless steel construction offers corrosion resistance in environments with exposure to moisture or mild chemicals.

Key Features

• Flanged design with a flange outside diameter of 0.296 inches for positive axial retention
• Double-shield construction protects internal raceways from debris and contamination
• ABEC-5 precision rating for tight dimensional tolerances and reduced runout
• Stainless steel housing provides corrosion resistance in demanding environments
• Single-row, round bore configuration with a 70-pound dynamic load capacity
• No snap ring required — flange provides integral housing location

Compatibility

Designed as a direct-replacement miniature flanged ball bearing for applications requiring a 0.0781-inch bore, 0.25-inch OD, and 0.1406-inch width with double-shield and ABEC-5 specifications.

Installation Notes

Installation should be performed by qualified mechanical technicians familiar with precision bearing handling procedures. Power down and de-energize all associated equipment before removing or installing bearings. Press or seat bearings by applying force only to the ring being fitted — never drive force through the rolling elements. Handle stainless steel miniature bearings carefully to avoid contaminating or damaging the shields or raceways prior to installation.
