Standard Diameter: 1-1/16″ / 1.0625 Inches

Metric Diameter: 26.9875mm

Grade: 500

Material: AISI 1015 Carbon Steel

Ball Weight (each): 2.828 Ounces / 80.16 Grams

Carbon steel balls offer the precise geometry and fine surface finish that makes them especially useful for bicycles, casters, drawer slides, door locks and many other applications. AISI 1015 is a low-carbon steel that offers superior workability and machinability. A versatile engineering and machinery alloy, AISI 1015 is used normalized, hot-rolled, cold-worked or annealed.

Standard Diameter: 1-1/2″ / 1.50 Inches

Metric Diameter: 38.10mm

Grade: 100

Material: AISI 52100 Chromium Steel

Ball Weight (each): 7.9708 Ounces / 225.967 Grams

Chrome steel balls offer the precise geometry and fine surface finish that makes them especially useful for bicycles, casters, drawer slides, door locks and many other applications.

Standard Diameter: 1-1/2″ / 1.50 Inches

Metric Diameter: 38.10mm

Grade: 100

Material: 440 Stainless Steel

Ball Weight (each): 7.9708 Ounces / 225.967 Grams

440 stainless steel balls offer the precise geometry and fine surface finish that makes them especially useful for bicycles, casters, drawer slides, door locks and many other applications with the added benefit of corrosion resistance. 440 stainless steel is a high carbon martensitic stainless steel which has high strength, good hardness and wear resistance. This type of stainless is capable of attaining, after heat treatment, the highest strength, hardness and wear resistance of all the stainless alloys. Unlike some stainless steel, this 400 series metal has a composition which allows it to be attracted to a magnet.

Standard Diameter: 3/16″ / .1875 Inches

Metric Diameter: 4.7625mm

Grade: 5

Material: Si3N4 Silicon Nitride

Ball Weight (each): .006473 Ounces / 0.1836 Grams

Silicon Nitride (Si3N4) Ceramic Balls are formed from a new material suitable for applications where high loads, high speeds and extreme temperatures are factors. Long life and the need for minimal lubrication make this material appropriate for extreme applications. Silicon nitride is a non-porous, non-magentic, non corrosive, and lighter than steel material. Silicone nitride balls are harder than steel allowing them to withstand the most rigorous environments. Ceramic balls are almost friction-less because they are non-porous which gives them the ability to spin faster than steel balls.
