Value Collection SFRW166-ZZ Miniature Ball Bearing

Product Description

The VALUE COLLECTION SFRW166-ZZ is a miniature flanged ball bearing designed for precision rotating assemblies where compact dimensions and reliable load handling are required. This single-row bearing features a 0.1875 inch bore diameter, a 0.375 inch outside diameter, and an overall width of 0.125 inches, making it suited for small-envelope applications. Constructed with a stainless steel housing, it carries a double-shield configuration and an ABEC-5 precision rating. The flange outside diameter measures 0.422 inches, providing positive axial location in flanged housings. Licensed technicians and precision equipment mechanics working on light industrial, instrumentation, and small-motor assemblies are the primary installers of this bearing.

This bearing is applied in residential and light commercial equipment where small shaft sizes and tight housing bores are standard. Common applications include small electric motors, pumps, fans, instrumentation drives, and precision mechanical assemblies requiring a compact, shielded bearing with defined static and dynamic load ratings. The flanged style seats positively against a bore shoulder, preventing axial migration without additional retaining hardware. Its stainless steel construction provides corrosion resistance suitable for environments with moisture exposure or periodic washdown.

Key Features

• ABEC-5 precision rating for reduced runout in instrumentation and small-motor applications
• Double-shield design keeps lubricant in and contaminants out without requiring external seals
• Flanged style with 0.422 inch flange OD for positive axial location in bored housings
• Stainless steel housing for corrosion resistance in wet or humid environments
• 160 pounds dynamic load capacity and 56 pounds static load capacity
• Single-row, round bore design for straightforward shaft installation

Compatibility

Designed as an OEM-style replacement miniature flanged ball bearing for precision mechanical assemblies requiring a 0.1875 inch bore, 0.375 inch OD, double-shielded, flanged configuration. The manufacturer bearing number for this unit is SFRW166ZZ.

Installation Notes

Installation should be performed by a qualified mechanic or technician familiar with precision bearing fits. De-energize and lock out all power to the equipment before removing or installing bearings. Use a proper bearing press or driver tool sized to the ring being pressed — never strike the bearing directly with a hammer, and never apply installation force through the rolling elements. Verify shaft and housing tolerances match the bearing specifications before pressing to avoid premature failure.
