Value Collection SR156 Miniature Ball Bearing Open

Product Description

The VALUE COLLECTION SR156 is a miniature ball bearing designed for precision rotating applications where compact dimensions and reliable load handling are required. With a 0.1875-inch bore diameter, a 0.3125-inch outside diameter, and an overall width of 0.1094 inches, this single-row bearing fits into tight clearances common in small motors, fans, instruments, and light mechanical assemblies. It carries a static load capacity of 29 pounds and a dynamic load capacity of 81 pounds. The open style and stainless steel housing make it suitable for environments where rust resistance is a priority and external lubrication access is needed.

This bearing is used in applications requiring a miniature form factor with moderate load capacity. Typical installations include small electric motors, HVAC blower shaft assemblies, pump impeller shafts, instrumentation, and other rotating equipment where bore and outer diameter constraints drive the bearing selection. The ABEC-5 tolerance rating makes it appropriate for applications demanding tighter dimensional accuracy and reduced runout compared to standard ABEC-1 or ABEC-3 bearings.

Key Features

• Miniature form factor: 0.1875-inch bore, 0.3125-inch OD, 0.1094-inch width
• Single-row design rated for 29 pounds static and 81 pounds dynamic load capacity
• ABEC-5 tolerance class for tighter dimensional accuracy and lower runout
• Stainless steel housing for corrosion resistance in humid or washdown-prone environments
• Open style allows direct lubrication and suits cleaner operating environments
• No flange, no snap ring — standard round bore for straightforward shaft mounting

Compatibility

Designed as a standard SR156 miniature ball bearing replacement suitable for small motors, instrumentation, and light rotating mechanical assemblies requiring a 0.1875-inch bore and 0.3125-inch outside diameter with ABEC-5 precision.

Installation Notes

Installation is typically performed by mechanical technicians or trained service personnel using a bearing press or appropriate driver to avoid side-loading the races. Always power down and de-energize the equipment before servicing any bearing. Do not hammer directly on the bearing outer ring or inner race. Ensure the shaft and housing are clean and within specified tolerance before pressing the bearing into place.
