Value Collection SFR4ZZ Miniature Ball Bearing Flanged

Product Description

The VALUE COLLECTION SFR4ZZ is a miniature ball bearing designed for compact rotating assemblies that require precise, low-friction support under moderate radial and axial loads. Built with a stainless steel housing, it features a double-shield configuration that keeps contaminants out while retaining lubrication. The bore diameter measures 0.25 inches, the outside diameter is 0.625 inches, and the overall width is 0.196 inches. With a dynamic load capacity of 335 pounds and a static load capacity of 128 pounds, this bearing handles demanding duty cycles in a small footprint. It carries an ABEC-5 precision rating, making it suitable for applications requiring tighter tolerances than standard commercial-grade bearings.

This bearing is suited for light industrial equipment, small motors, fans, instrumentation, and other precision assemblies where a compact flanged bearing is required. The integral flange, with an outside diameter of 0.69 inches, simplifies housing design by providing a positive axial stop without additional hardware. It is installed by mechanical technicians and maintenance professionals working on small rotating equipment in both commercial and light industrial environments.

Key Features

• Flanged design with 0.69-inch flange outside diameter for easy axial positioning
• Double-shield construction reduces contamination ingress and retains lubrication
• Stainless steel housing for corrosion resistance in washdown or humid environments
• ABEC-5 precision rating for tighter dimensional tolerances
• Single-row construction with round bore for straightforward shaft mounting
• 335-pound dynamic load capacity and 128-pound static load capacity in a miniature form factor

Compatibility

Designed as an OEM-style replacement miniature flanged ball bearing for compact rotating assemblies requiring a 0.25-inch bore, 0.625-inch OD, and 0.196-inch width with a double-shield flanged configuration.

Installation Notes

Installation should be performed by a qualified mechanical technician familiar with precision bearing service procedures. Before servicing any rotating equipment, de-energize and lock out the machine per applicable LOTO procedures. Press or seat the bearing using a proper bearing installation tool applied to the correct race ring — never strike the bearing directly with a hammer or apply force across the rolling elements. Ensure the housing bore and shaft are clean and within specified tolerances before installation.
