Value Collection SR133ZZ Miniature Ball Bearing ABEC-5

Product Description

The VALUE COLLECTION SR133ZZ is a miniature radial ball bearing designed for precision applications requiring a small form factor and reliable rotational performance. It features a round bore of 0.0937 inches, an outside diameter of 0.1875 inches, and an overall width of 0.0937 inches. The double-shield design protects the internal raceways from contamination in demanding service environments. Rated at ABEC-5 tolerance, this bearing suits applications where dimensional accuracy and low runout matter. The stainless steel housing resists corrosion, making it suitable for use in wet or chemically exposed environments. Licensed HVAC, mechanical, and industrial equipment technicians install this type of bearing in small motors, instruments, and precision assemblies.

This miniature ball bearing is used in single-row radial load applications where tight tolerances and a compact envelope are required. Typical installations include small electric motors, blower wheel shafts, instrumentation, medical devices, and light-duty precision machinery. It carries a static load capacity of 10 pounds and a dynamic load capacity of 31 pounds, making it appropriate for low-to-moderate load scenarios within its dimensional class. No flange is present, allowing straight housing bore mounting. No snap ring is included.

Key Features

• ABEC-5 tolerance rating for precision dimensional accuracy and reduced runout
• Double-shield design protects internal raceways from dust and debris
• Stainless steel housing construction for corrosion resistance in wet or chemical environments
• Single-row configuration handles radial loads in compact assemblies
• 31-pound dynamic load capacity and 10-pound static load capacity within a miniature footprint
• No flange, no snap ring — clean profile for straight bore housing installations

Compatibility

Designed as a direct replacement or equivalent for applications specifying bearing number SR133Z in miniature single-row radial ball bearing configurations. Fits housings requiring a 0.1875-inch OD and a 0.0937-inch bore with a 0.0937-inch width.

Installation Notes

Installation should be performed by a qualified mechanic or technician familiar with precision bearing handling. Always de-energize and lock out the equipment before removing or installing bearings. Press or drive force should be applied evenly to the correct bearing ring — pressing on the wrong ring can damage the raceways or rolling elements. Avoid impact loading during installation; use a proper bearing press or driver sized to the bearing OD or bore as appropriate for the housing or shaft fit.
