Value Collection SR188 Miniature Ball Bearing Open

Product Description

The VALUE COLLECTION SR188 is a miniature ball bearing designed for precision rotating assemblies in light-duty mechanical and industrial applications. Built to ABEC-5 tolerances, it offers a 0.25 inch bore diameter, 0.5 inch outside diameter, and a width of 0.125 inches. The open style construction allows for direct lubrication access and suits environments where low-profile, compact bearing solutions are required. With a static load capacity of 90 pounds and a dynamic load capacity of 243 pounds, this single-row bearing handles moderate radial loads in a small form factor. The stainless steel housing provides corrosion resistance for demanding service conditions. Technicians, machinists, and maintenance professionals install this bearing in precision equipment where dimensional accuracy and load rating are critical.

This miniature ball bearing is suited for use in small motors, instrumentation, light conveyance equipment, and precision mechanical assemblies across residential, commercial, and industrial settings. The round bore and unflanged design simplify drop-in replacement and retrofit installations. Its single-row configuration is appropriate for applications with primarily radial loading and minimal axial thrust. No snap ring is included, so housing design should account for standard retention methods.

Key Features

• ABEC-5 rated for precision dimensional tolerances and reduced runout
• Stainless steel housing provides corrosion resistance in wet or chemically active environments
• Open style allows direct lubrication or relubrication in service
• Single-row design handles radial loads in compact installations
• 243 pound dynamic load capacity and 90 pound static load capacity in a 0.5 inch OD envelope
• Unflanged, round bore construction for straightforward press-fit or slip-fit installations

Compatibility

Designed as an OEM-style replacement or direct substitute for miniature ball bearings with a 0.25 inch bore, 0.5 inch outside diameter, and 0.125 inch width conforming to SR188 dimensional standards.

Installation Notes

Installation is typically performed by a machinist, maintenance technician, or mechanical trade professional. Always de-energize and lock out the equipment before removing or installing bearings. Use a proper bearing press or driver tool to apply force evenly to the bearing race during installation — never strike the bearing directly with a hammer. Verify housing and shaft tolerances before installation to ensure correct fit and avoid premature bearing failure.
