Value Collection SR4ZZ Miniature Ball Bearing ABEC-5

Product Description

The VALUE COLLECTION SR4ZZ is a miniature radial ball bearing designed for precision applications requiring a compact, double-shielded design. Built with a stainless steel housing, this single-row bearing carries an ABEC-5 tolerance rating, indicating tighter dimensional control than standard ABEC-1 or ABEC-3 bearings. It supports a static load capacity of 128 pounds and a dynamic load capacity of 335 pounds. The double-shield configuration helps retain lubrication and block contaminants without requiring contact seals, making it well suited for moderate-speed, light-load applications where dimensional accuracy and cleanliness matter.

This bearing is used in light-duty mechanical assemblies across a wide range of industries, including HVAC equipment, small motors, pumps, power tools, and precision instruments. The 0.25-inch bore, 0.625-inch outside diameter, and 0.196-inch width fit standard shaft and housing designs common in small rotating equipment. It is installed by millwrights, equipment technicians, and maintenance professionals working on motors, fans, conveyors, and similar assemblies requiring a compact, high-tolerance bearing.

Key Features

• Double-shield style retains grease and reduces contamination ingress without seal drag
• ABEC-5 tolerance class for tighter runout and dimensional accuracy versus standard grades
• Stainless steel housing for improved corrosion resistance in humid or washdown environments
• 335-pound dynamic load capacity and 128-pound static load capacity in a miniature form factor
• Round bore without flange, compatible with standard shaft and housing fits
• Single-row construction for radial load applications with minimal axial space

Compatibility

Designed as an OEM-style replacement or drop-in for miniature ball bearing applications calling for bearing number SR4ZZ with a 0.25-inch bore, 0.625-inch outside diameter, and 0.196-inch width.

Installation Notes

Installation should be performed by qualified mechanical technicians familiar with bearing press fits and shaft tolerances. Always de-energize and lock out equipment before replacing bearings. Use a proper bearing press or installation sleeve to apply force to the correct bearing race — never strike the bearing directly with a hammer. Inspect the shaft and housing bore for wear, scoring, or out-of-round conditions before pressing in the new bearing.
