Value Collection SFRW188-ZZ Miniature Flanged Ball Bearing

Product Description

The VALUE COLLECTION SFRW188-ZZ is a miniature flanged ball bearing designed for precision rotating applications where space is limited and load capacity must remain reliable. This double-row bearing features a 0.25 inch bore diameter, a 0.5 inch outside diameter, and an overall width of 0.1875 inches. The stainless steel housing provides corrosion resistance in demanding environments. Rated to ABEC-5 tolerances, it delivers controlled runout and dimensional accuracy suitable for light machinery, instrumentation, small motors, and precision mechanical assemblies. Double shields on both faces protect the internal raceways from contamination without requiring external sealing in the application design.

This bearing is suited for use in compact rotating assemblies found in small electric motors, pumps, fans, encoders, medical devices, and light-duty industrial equipment. The flanged configuration allows the bearing to be retained axially in a housing bore without additional hardware, simplifying installation in thin-panel or cartridge-style mounting arrangements. Its 2-row design supports combined radial and axial loading, making it appropriate for applications where both load directions are present simultaneously.

Key Features

• 0.25 inch round bore diameter for standard miniature shaft fitment
• ABEC-5 precision rating for controlled dimensional tolerances and low runout
• Double-shield design protects internal raceways from dust and debris
• Stainless steel housing material for corrosion and moisture resistance
• Flanged outer ring allows axial retention without snap rings or external clips
• 90 lb static load capacity and 243 lb dynamic load capacity for reliable performance under combined loading

Compatibility

Designed as an OEM-style replacement or direct-fit miniature flanged ball bearing for precision rotating assemblies requiring a 0.25 inch bore, 0.5 inch OD, and ABEC-5 rated double-shield construction. Bearing number cross-reference: SFRW188ZZ.

Installation Notes

Installation should be performed by a qualified technician familiar with precision bearing handling. Always de-energize and lock out equipment before removing or installing bearings. Press or drive force should be applied only to the bearing ring being fitted into the housing or onto the shaft — never apply force through the rolling elements. Handle stainless steel bearings with clean, dry tools to avoid contamination of the raceways prior to installation.
