Value Collection SFR133ZZS Miniature Flanged Ball Bearing

Product Description

The Value Collection SFR133ZZS is a miniature flanged ball bearing designed for precision rotating assemblies that require a compact, low-profile rolling element solution. Built from stainless steel, this single-row bearing carries an ABEC-5 precision rating and features a double-shield design to keep contaminants out of the raceway without the drag of a contact seal. It handles a static load capacity of 10 pounds and a dynamic load capacity of 31 pounds, making it suitable for light-duty, high-speed spindle and instrument applications where dimensional accuracy and cleanliness matter.

This bearing is used in miniature machinery, instrumentation, small motor assemblies, and precision equipment where bore and envelope dimensions are tightly constrained. The integral flange provides positive axial location in a housing bore, simplifying installation and reducing the need for additional retaining hardware. With a bore diameter of 0.0937 inches, an outside diameter of 0.1875 inches, and an overall width of 0.0937 inches, it fits applications calling for a bearing in the SFR1-4ZZ size class. Typical installers include mechanical technicians, instrumentation specialists, and precision equipment repair technicians.

Key Features

• Stainless steel housing material for corrosion resistance in wash-down or humid environments
• ABEC-5 precision rating for reduced runout and tighter dimensional tolerances
• Double-shield construction limits contamination ingress without contact-seal friction
• Flanged design provides positive axial location in counterbored housings
• Single-row construction suits radial and moderate thrust load combinations
• Bearing number SFR1-4ZZ for cross-reference and replacement identification

Compatibility

Designed as an OEM-style replacement or direct-fit miniature ball bearing for applications requiring an SFR1-4ZZ flanged double-shield bearing with a 0.0937-inch bore and 0.1875-inch outside diameter.

Installation Notes

Press-fit or slip-fit installation should be performed with a proper bearing press or installation mandrel applied to the appropriate bearing ring — never drive a bearing in by striking the rolling elements or opposite race. Ensure the housing bore and shaft are clean and within specified tolerance before installation. Avoid metal-to-metal contact that could score the shield during handling. Technicians should follow equipment OEM service procedures and applicable industry standards when servicing precision rotating assemblies.
