Value Collection SFR3ZZ Miniature Flanged Ball Bearing

Product Description

The VALUE COLLECTION SFR3ZZ is a miniature flanged ball bearing designed for applications requiring precise, low-friction rotational support in compact assemblies. Built from stainless steel housing, this single-row bearing features a double-shield configuration that protects internal components from contamination and debris. With a bore diameter of 0.1875 inches and an outside diameter of 0.5 inches, it fits tight-tolerance shaft and housing arrangements common in light mechanical, HVAC blower motor sub-assemblies, and small equipment drives. The ABEC-5 precision rating ensures dimensional accuracy and low runout, making it suitable where standard ABEC-1 or ABEC-3 bearings are insufficient. Maintenance technicians and mechanical assemblers typically install this bearing during equipment overhaul or sub-assembly replacement.

This bearing is suited for residential and light commercial equipment where miniature-scale rotating components require reliable radial load support. The flanged outer ring simplifies axial positioning and retention within a housing bore, eliminating the need for snap rings or retaining clips in many designs. The double-shield construction limits grease migration and reduces ingress of fine particulates, extending service intervals in moderate-duty applications. Typical install scenarios include small motor shaft support, fan blade assemblies, and precision instrument drives where dimensional consistency is critical.

Key Features

• Flanged outer ring with a flange outside diameter of 0.565 inches for positive axial location in housing
• Double-shield design protects internal raceways and grease from contamination
• Stainless steel housing construction for corrosion resistance
• ABEC-5 precision rating for tight dimensional tolerances and low runout
• Static load capacity of 108 pounds and dynamic load capacity of 293 pounds
• Single-row construction with a width of 0.196 inches for compact axial footprint

Compatibility

Designed as an OEM-style replacement or direct-fit miniature flanged ball bearing for equipment specifying bearing number SFR3ZZ with a 3/16-inch bore, 0.5-inch outside diameter, and flanged double-shield configuration.

Installation Notes

Installation should be performed by a qualified mechanic or technician familiar with precision bearing handling. De-energize and lock out all power to the equipment before replacing any rotating components. Press or seat the bearing using a proper bearing press or driver sized to contact the outer race only — never strike the inner race directly, as this can damage raceways and reduce bearing life. Follow applicable equipment manufacturer torque specifications for any fasteners securing the housing or end caps.
