Value Collection SR1-4ZZ Miniature Ball Bearing Double Shield

Product Description

The VALUE COLLECTION SR1-4ZZ is a miniature ball bearing designed for precision radial load applications in compact mechanical assemblies. Built with a stainless steel housing and a double-shield configuration, this single-row bearing controls contamination ingress while maintaining a low-profile footprint. It carries a dynamic load capacity of 70 pounds and a static load capacity of 23 pounds, making it well suited for light-duty spindle, motor shaft, and instrument applications where space is constrained. Rated ABEC-5, it meets closer dimensional and running-accuracy tolerances than standard ABEC-1 or ABEC-3 bearings, which matters in high-speed or precision-positioning scenarios.

This bearing is a common fit in small electric motors, fans, instrumentation, medical devices, and light industrial equipment where bore and outside diameter envelopes are tight. The 0.0781-inch bore, 0.25-inch outside diameter, and 0.1406-inch overall width allow it to drop into housings designed for fractional-inch miniature bearing standards. It is typically installed by mechanical technicians, OEM assembly personnel, and field service technicians working on precision rotating equipment.

Key Features

• Double-shield design reduces contamination exposure without requiring lubrication-sealed construction
• Stainless steel housing resists corrosion in humid or lightly washdown-exposed environments
• ABEC-5 tolerance rating ensures tighter dimensional accuracy for precision or higher-speed applications
• Single-row, round-bore, non-flanged profile fits standard miniature bearing housings
• 70-pound dynamic load capacity and 23-pound static load capacity for light radial load service
• No snap ring included; mounts by press fit or standard retaining methods into the housing bore

Compatibility

Designed as an OEM-style replacement miniature ball bearing for precision mechanical assemblies requiring a 0.0781-inch bore, 0.25-inch outside diameter, and 0.1406-inch width in a double-shield, non-flanged configuration.

Installation Notes

Installation should be performed by qualified mechanical or maintenance technicians. Always de-energize and lock out equipment before replacing bearings. Use a proper bearing press or driver tool to apply installation force to the bearing ring being seated — never strike the bearing directly or apply force through the rolling elements. Inspect the mating shaft and housing bore for wear, scoring, or out-of-round conditions before fitting the new bearing.
