Value Collection SR188ZZ Miniature Ball Bearing ABEC-5

Product Description

The VALUE COLLECTION SR188ZZ is a single-row miniature ball bearing built for precision applications that demand tight tolerances and compact dimensions. It features a 0.25 inch bore diameter, a 0.5 inch outside diameter, and an overall width of 0.1875 inches. The double-shield design protects internal raceways from contamination while keeping the assembly compact. Rated ABEC-5, this bearing meets close dimensional and running-accuracy tolerances suitable for high-speed or precision equipment. The stainless steel housing provides corrosion resistance in demanding environments. Static load capacity is 90 pounds and dynamic load capacity is 243 pounds. Technicians and equipment maintenance professionals install this bearing in precision machinery, small motors, and instrumentation.

This miniature ball bearing suits residential and light commercial applications where space is limited and accurate shaft alignment is critical. Typical installations include small electric motors, fans, pumps, precision instruments, and mechanical assemblies found in HVAC equipment, pool equipment controls, and similar trade hardware. The round bore and non-flanged profile allow for straightforward press-fit or slip-fit installation into standard housings without additional mounting hardware. No snap ring is included.

Compatibility

Designed as a direct replacement for standard SR188ZZ miniature ball bearings used in precision motors, small fans, pumps, and instrumentation assemblies that accept a 0.25 inch bore, 0.5 inch OD, 0.1875 inch wide bearing.

Installation Notes

Installation is typically performed by a qualified mechanic or equipment technician. Power down and lock out all equipment before removing the old bearing or pressing in the replacement. Use an appropriate bearing press or driver that applies force evenly to the bearing race to avoid damage to the shields or raceways. Do not apply installation force through the rolling elements.
