9mm Loose Steel Balls
Starting at £2.84 £2.37
Our 9mm steel balls are made from AISI 52100 Grade 100 Chrome Steel. This compound is made from Chromium, Manganese, Carbon, Silicon, Phosphorus, Sulfur and Ferrite. These chemicals together form a hard, finely grained Martensitic Steel. This alloy is remarkably resistant to corrosion and wear, making it an excellent choice for applications involving heavy loads and high speed.
Typical uses for these balls, aside from inside bearings, include cocoa grinders, spray paint agitators, one way valves and even decoration. San Francisco International Airport has 5 foot diameter ball bearings supporting the building, which helps minimise damage during earthquakes.
Our 9mm Steel balls are available in packs of 10, 100, 200, 500 or 1000.
