Value Collection SR155 Miniature Ball Bearing Open Stainless

Product Description

The VALUE COLLECTION SR155 is a single-row miniature ball bearing designed for precision rotating applications where tight tolerances and compact dimensions are required. With a bore diameter of 0.1562 inches, an outside diameter of 0.3125 inches, and an overall width of 0.1094 inches, this bearing fits into space-constrained assemblies across a wide range of light mechanical equipment. It carries a static load capacity of 29 pounds and a dynamic load capacity of 81 pounds, making it suitable for low-to-moderate load applications. The stainless steel housing and open style construction allow for direct lubrication access while offering corrosion resistance in light-duty environments. Rated ABEC-5, it meets precision-class standards for reduced runout and tighter dimensional tolerances.

This bearing is commonly used in small motors, fans, pumps, instrumentation, and other rotating assemblies found in HVAC equipment, plumbing devices, and electrical components. The open design suits applications where external lubrication is applied during maintenance. It is installed by mechanical technicians and equipment repair professionals working on light-duty rotating machinery. No snap ring or flange is included, and the round bore accepts standard shaft fits for straightforward press or slip-fit installation.

Key Features

• ABEC-5 precision rating for reduced radial runout and tight dimensional tolerances
• Stainless steel housing provides corrosion resistance in light-duty service environments
• Open style allows direct access for external lubrication during routine maintenance
• Static load capacity of 29 pounds and dynamic load capacity of 81 pounds
• No flange and no snap ring — clean profile for compact bearing seats
• Single-row construction suited for radial load applications in small rotating assemblies

Compatibility

Designed as an OEM-style replacement miniature ball bearing for single-row, open-style applications requiring a 0.1562-inch bore, 0.3125-inch outside diameter, and 0.1094-inch width with an ABEC-5 precision rating.

Installation Notes

Power down and de-energize any equipment before removing or installing bearings. Press-fit installation should use a proper bearing press or driver tool applied to the bearing race, never to the rolling elements or cage. Confirm shaft and housing dimensions are within tolerance before installation to avoid premature wear. Consult equipment manufacturer documentation for lubrication type and relubrication intervals appropriate to the application.
