Value Collection 20219 316 Ss Precision Ball 0.5 in Grade 100

Product Description

The VALUE COLLECTION 20219 is a Grade 100 precision ball manufactured from 316 stainless steel, engineered for applications that demand tight dimensional tolerances and corrosion resistance. At 0.5 inches in diameter, this ball meets stringent Grade 100 standards with a sphericity of 0.0001 inches and a diameter deviation of 0.0001 inches. Hardness is rated at 40 to 45 HRC, providing the surface durability needed for load-bearing, metering, and flow-control applications. These balls are sold in a package quantity of 10 units per order.

This precision ball is suited for use in valves, pumps, check assemblies, bearings, and instrumentation components across industrial, marine, chemical processing, and fluid-handling environments. The 316 stainless steel alloy provides strong resistance to chloride corrosion, making it appropriate for both indoor and outdoor installations where exposure to moisture, salt, or mild chemicals is a concern. Machinists, maintenance technicians, and MRO professionals are the typical end users.

Key Features

• Grade 100 precision rating with 0.0001-inch sphericity and 0.0001-inch diameter deviation
• 316 stainless steel construction for superior corrosion and chloride resistance
• 40 to 45 HRC surface hardness for durability in load-bearing and wear-contact applications
• 0.5-inch diameter suits a wide range of standard valve and bearing assemblies
• Sold in packs of 10, with single-unit minimum order quantity

Compatibility

Designed as a precision replacement or component ball for standard 0.5-inch seat applications in valves, check valves, pumps, and bearing assemblies requiring Grade 100 tolerances and 316 stainless steel material.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians during valve, pump, or bearing assembly or rebuild. Inspect the mating seat or race for wear or scoring before installing a new ball to avoid premature failure. Clean all mating surfaces and ensure no debris is present in the assembly bore prior to placement. Follow the equipment manufacturer's torque and assembly specifications for the host component.
