Value Collection SFR166ZZ Miniature Ball Bearing Flanged

Product Description

The Value Collection SFR166ZZ is a miniature ball bearing designed for light-load, precision applications where compact size and reliable performance are required. Flanged and double-shielded, it features a 0.1875-inch bore diameter and a 0.375-inch outside diameter with an overall width of 0.125 inches. The stainless steel housing provides corrosion resistance suitable for demanding environments. Rated ABEC-5 for dimensional accuracy, this single-row bearing delivers a static load capacity of 56 pounds and a dynamic load capacity of 160 pounds. It is commonly installed by mechanical technicians and equipment service professionals working on small motors, instruments, or precision assemblies.

This bearing is suited for use in residential and light commercial equipment where miniature, high-precision bearings are specified. Typical applications include small electric motors, fans, pumps, medical devices, and instrumentation. The flanged design with a 0.422-inch flange outside diameter allows for straightforward axial location within a housing bore, simplifying installation in assemblies where positional control is critical. The double-shield construction helps retain lubrication and exclude contaminants without requiring contact seals.

Compatibility

Designed as an OEM-style replacement or service bearing for equipment specifying a miniature flanged ball bearing with a 0.1875-inch bore, 0.375-inch OD, and 0.125-inch width in the SFR166ZZ bearing series.

Installation Notes

Installation should be performed by a qualified mechanical technician or equipment service professional. De-energize and lock out all power to the equipment before removing or installing bearings. Use appropriate pressing or setting tools applied to the bearing race — never strike the bearing directly or apply force through the rolling elements. Verify housing bore and shaft dimensions match the bearing specifications before installation to avoid premature failure.
