Value Collection SFR188ZZ Miniature Flanged Ball Bearing

Product Description

The VALUE COLLECTION SFR188ZZ is a miniature flanged ball bearing designed for compact rotating assemblies where precise, low-friction motion is required. It features a 0.25 inch bore diameter, a 0.5 inch outside diameter, and an overall width of 0.1875 inches. The double-shield design protects the internal raceway from debris and contamination without adding significant drag. Constructed with a stainless steel housing, the SFR188ZZ carries a static load capacity of 90 pounds and a dynamic load capacity of 243 pounds. It is rated ABEC-5, indicating a higher level of dimensional accuracy suitable for precision mechanical applications. A fixed flange with a 0.547 inch flange outside diameter simplifies axial retention during installation.

This bearing is used in precision mechanical equipment, small motors, instruments, and light-duty industrial assemblies where a compact form factor is essential. The flanged style seats against a housing shoulder to provide positive axial location without additional snap rings or retaining hardware. Single-row construction keeps the assembly profile thin. It is appropriate for residential and commercial applications involving small-diameter shaft assemblies, and is typically installed by mechanical technicians, maintenance professionals, or equipment repair technicians working on precision rotating components.

Key Features

• Flanged design with 0.547 inch flange OD for positive axial retention in a housing bore
• Double-shield construction keeps contaminants away from the internal raceway
• Stainless steel housing for corrosion resistance in demanding environments
• ABEC-5 precision rating for dimensional accuracy in close-tolerance applications
• 90 pound static load capacity and 243 pound dynamic load capacity
• Single-row, round bore configuration for straightforward shaft fitment

Compatibility

Designed as an OEM-style replacement or direct-fit bearing for compact rotating assemblies requiring a 0.25 inch bore, 0.5 inch OD, flanged miniature ball bearing with an ABEC-5 rating and double-shield configuration.

Installation Notes

Installation should be performed by a qualified mechanical technician. De-energize and lock out all equipment before removing or installing bearings. Press or seat the bearing using a proper bearing installation tool applied to the outer ring only — never strike the inner ring directly, as this can damage the raceway. Verify shaft and housing dimensions are within tolerance before pressing to avoid premature failure.
