Drilled Steel Balls

Precision steel balls are manufactured to tight tolerances for size, roundness, and surface finish, ensuring consistent performance in critical applications. For drilled steel balls, precision includes accurately centered through-holes for rod or tube attachment, allowing smooth, reliable movement in float valves and liquid level measurement systems.

A drilled steel ball is a stainless steel ball with a hole bored through its center or a through-tube fitted, allowing it to slide along a rod or cable. This design is commonly used in float valve assemblies and liquid level measurement systems where guided vertical movement is required.

Drilled steel balls are typically manufactured from 304 or 316 stainless steel, chosen for their corrosion resistance and durability. 316 stainless steel offers enhanced resistance to corrosive chemicals, making it preferred for chemical manufacturing and wastewater applications, while 304 stainless steel suits most general industrial and food processing uses.

Yes, drilled steel balls can be customized with a wide range of thread specifications, including 1/4-20, 3/8-16, 1/4 NPT, 3/8 NPT, and 3/4 NPT, along with custom fittings, hooks, and through-tubes sized to fit rods from 3/8" to 3/4" in diameter, matching specific system requirements.

Round drilled steel balls are commonly available in sizes ranging from 1-1/2" to 14" in diameter, while oblong floats range from 2"x6" up to 9"x14". Custom sizes outside these standard ranges can also be manufactured to match specific tank, valve, or measurement device requirements.

Yes, drilled steel balls can be pressure-tested using dedicated equipment to meet customer-specified pressure ratings before shipment. This is especially important for applications like vacuum tanks, steam traps, and high-pressure chemical processing systems where reliable sealed performance is critical for safe operation.
