Value Collection 20182 Grade 100 440-C Steel Precision Ball

Product Description

The VALUE COLLECTION 20182 is a Grade 100 precision ball machined from 440-C stainless steel, designed for applications that demand tight dimensional tolerances and high surface hardness. This ball measures 0.375 inches in diameter with a diameter deviation of 0.0005 inches and a sphericity of 0.0005 inches, meeting Grade 100 specifications for precision ball standards. The 440-C alloy delivers a hardness range of 57 to 61 HRC, making it well-suited for bearing assemblies, valves, fluid control components, and industrial machinery where corrosion resistance and wear performance are critical factors.

This precision ball is commonly used in ball bearing assemblies, check valves, flow control valves, and precision instrumentation across industrial, hydraulic, and pneumatic systems. The 440-C stainless alloy provides good corrosion resistance in mildly corrosive environments, making it appropriate for both wet and dry operating conditions. Maintenance technicians, millwrights, and industrial mechanics typically source these balls for OEM replacements or component-level repairs in mechanical systems requiring tight roundness and surface finish tolerances.

Key Features

• Grade 100 precision rating with 0.0005 inch diameter deviation
• Sphericity of 0.0005 inches for tight roundness consistency
• 440-C stainless steel construction with 57 to 61 HRC hardness range
• Corrosion-resistant alloy suitable for mildly corrosive service environments
• Consistent dimensional tolerances support direct OEM-style replacement use

Compatibility

Designed as a Grade 100 precision replacement ball for bearing assemblies, check valves, and fluid control components that accept a 0.375 inch diameter ball in 440-C stainless steel.

Installation Notes

Installation is typically performed by millwrights, bearing technicians, or valve service mechanics. Ensure all system pressure is fully relieved and equipment is de-energized or depressurized before disassembling any bearing housing or valve body. Handle precision balls with clean, dry tools or gloves to prevent surface contamination that could affect seating and service life. Verify seat and race dimensions before installation to confirm proper fit within tolerance.
