Value Collection SR3 Miniature Ball Bearing ABEC-5

Product Description

The VALUE COLLECTION SR3 is a single-row miniature ball bearing built for precision applications requiring a compact, open-style design. With a 0.1875-inch bore diameter, 0.5-inch outside diameter, and 0.1562-inch overall width, it fits tight spaces where standard-sized bearings will not. The stainless steel housing provides corrosion resistance in demanding environments. Rated at ABEC-5 tolerance, it delivers consistent dimensional accuracy suitable for instrumentation, small motors, and precision mechanical assemblies. Static load capacity is 108 pounds and dynamic load capacity is 293 pounds. Maintenance technicians and equipment builders working with small-scale rotating assemblies will find this bearing a direct fit for a wide range of light-duty precision applications.

This miniature bearing is used in applications where space constraints demand a sub-one-inch outside diameter component. Typical install scenarios include small electric motors, fans, pumps, precision instruments, office equipment, and light industrial machinery. The open style allows for lubrication access during service intervals. The round bore and unflanged, no-snap-ring design make it straightforward to press or slip into standard bearing seats without additional hardware.

Key Features

• ABEC-5 tolerance rating for precise dimensional consistency in high-accuracy assemblies
• Stainless steel housing construction for corrosion resistance in wet or chemical-exposed environments
• Open style allows direct lubrication access during scheduled maintenance
• 108 lb static load capacity and 293 lb dynamic load capacity for reliable performance under load
• No flange, no snap ring — clean profile for straightforward installation into standard bearing seats
• Single-row design minimizes axial space requirements

Compatibility

Designed as an OEM-style replacement or direct-fit miniature ball bearing for applications requiring bearing number SR3 with a 0.1875-inch bore, 0.5-inch OD, and 0.1562-inch width.

Installation Notes

Installation is typically performed by mechanical technicians or equipment maintenance personnel using a bearing press or appropriate arbor tool — never drive the bearing in with impact force applied to the outer or inner race. Ensure the shaft and housing bore are clean and free of burrs before seating the bearing. Power down and de-energize all equipment before removing or installing bearings. Follow equipment manufacturer service documentation for fit tolerances and lubrication specifications.
