Value Collection 20107 Chrome Steel Ball Grade 25 1/4 in

Product Description

The VALUE COLLECTION 20107 is a Grade 25 chrome steel ball designed for precision bearing, metering, and mechanical assembly applications. Measuring 0.25 inches in diameter, this ball meets tight dimensional tolerances with a diameter deviation of 0.00005 inches and a sphericity of 0.000025 inches. Hardness runs from 62 to 66 C on the Rockwell scale, making it suitable for high-load and high-wear environments. Chrome steel construction provides strong resistance to surface fatigue and deformation under repeated contact stress. Sold in a package quantity of 100 balls per order.

Grade 25 chrome steel balls are widely used in ball bearings, check valves, pumps, flow controls, and industrial machinery. The tight sphericity and hardness range make them appropriate for applications where dimensional consistency directly affects performance, such as precision bearing assemblies and fluid metering components. These balls are used across HVAC, plumbing, fluid power, and general industrial equipment by mechanics, machinists, and assembly technicians.

Compatibility

Designed as a standard Grade 25 chrome steel ball for use in precision bearing assemblies, check valves, pumps, and mechanical components requiring a 0.25 inch diameter ball to ABMA Grade 25 specifications.

Installation Notes

Installation is typically performed by machinists, bearing technicians, or mechanical assembly professionals. Before servicing any assembly containing these balls, depressurize and de-energize the system as required by applicable safety procedures. Handle precision balls with clean, dry tools to avoid surface contamination that could affect dimensional performance. Consult the OEM assembly specifications for seat dimensions and preload requirements before installation.
