Value Collection SRW144ZZ Miniature Ball Bearing

Product Description

The VALUE COLLECTION SRW144ZZ is a single-row miniature ball bearing designed for applications requiring precise motion control in a compact envelope. With a 0.125-inch bore diameter and 0.25-inch outside diameter, this bearing fits tight-clearance assemblies where standard-size bearings will not. The double-shield design keeps contaminants out and retains lubrication without fully sealing the bearing cavity. Built from stainless steel housing material, it handles environments where corrosion resistance is a priority. A static load capacity of 20 pounds and a dynamic load capacity of 64 pounds make it suitable for light-duty rotational and linear support tasks. Licensed technicians and precision equipment assemblers are the primary installers of this component.

This miniature bearing suits residential and commercial equipment where small-diameter shafting is common, including motors, fans, instrumentation, robotics, actuators, and other precision mechanical assemblies. The 0.1094-inch overall width keeps the footprint minimal in axially constrained housings. Its ABEC-5 tolerance rating supports applications demanding tighter dimensional consistency than standard ABEC-1 or ABEC-3 bearings provide. The non-flanged, round-bore profile fits conventional cylindrical shaft and housing configurations without requiring a specialized mounting pocket.

Key Features

• 0.125-inch round bore diameter for precise shaft fit on small-diameter shafts
• 0.25-inch outside diameter suits compact housing bores
• Double-shield construction reduces contamination ingress and retains grease
• Stainless steel housing material provides corrosion resistance in wet or humid environments
• ABEC-5 tolerance rating for tighter dimensional accuracy than standard grades
• 64-pound dynamic load capacity and 20-pound static load capacity in a single-row configuration

Compatibility

Designed as an OEM-style replacement or direct-fit bearing for precision mechanical assemblies requiring a miniature single-row ball bearing with a 0.125-inch bore, 0.25-inch OD, and 0.1094-inch width in a double-shield, non-flanged configuration.

Installation Notes

Miniature ball bearings are typically installed by precision equipment technicians or mechanical assemblers using press-fit tools or bearing installation drivers sized to the outer race — never apply force directly to the rolling elements or inner race only. Verify shaft and housing tolerances before installation to avoid over-stressing the races. De-energize and lock out any equipment before removing or installing bearings. Handle stainless steel bearings carefully to avoid surface contamination that could accelerate corrosion at the race contact zones.
