Balls and Rollers Material Menu

Precision steel balls from sizes 1 mm to 6" in all grades to meet your needs. Available in the following materials.

CARBON STEEL BALLS AND ROLLERS

Low Carbon Aisi 1010-20 (CASE HARDENED)
Offering a significant cost savings compared to through hardened carbon, this material is recommended for applications involving only moderate load bearing, and non-precision bearings. Used in drawer slides, casters, and wheels.

High Carbon Aisi 1045-85 (THROUGH HARDENED)
Due to the higher carbon content, and heat treatment to harden the ball all the way through, these balls will offer longevity in wear and handle heavier loads. Examples of applications would include heavy equipment transportation (material handling) and slewing rings.

Soft Polish Carbon (NOT HARDENED)
Soft polish carbon balls are "soft" due to the absence of heat treatment or hardening. Thus, for non-loading bearing applications, applications involving welding, drilling/tapping, or further modification to the ball, soft polish is an excellent, economical alternative.

CHROME STEEL BALLS AND ROLLERS

52100 Chrome
Much harder than through hardened carbon due to its chrome content, 52100 steel offers good resistance to deformation. For these reasons, and its excellent wear resistance, it is a key player in ball bearing and roller bearing applications. 52100 Chrome is through hardened steel.

STAINLESS STEEL BALLS AND ROLLERS

AISI 440
This material offers maximum hardness due to its high chrome content, and deep freeze stabilization after heat treatment. When maximum hardness and good corrosion resistance to fresh water, steam, oil, gasoline, alcohol, foodstuffs, blood and perspiration are key factors in an application, 440 Stainless is recommended.

AISI 420
For applications requiring a steel ball with high hardness, and good inoxidability, Aisi 420 is suggested. Just slightly softer than 440 on the Rockwell Scale (HRc), this material offers a significant price savings to 440 Stainless. Aisi 420 Stainless resists fresh water, steam, oil, gasoline, blood, perspiration, alcohol, and foodstuffs. It is magnetic, and can be passivated upon request.

AISI 302/304
Not hardened like 420, steel balls in the "300 series stainless" are typically used when good corrosion is a key factor, particularly involving organic solutions. Such applications might include finger pumps or valves. This material is not successfully resistant to sulfuric acid.

AISI 316
Very similar to 302/304, but offering higher corrosion resistance due to the addition of molybdenum. Particularly resistant to sulfuric acid. Used in contact with dyes, bleaches, and inks. It is non-magnetic.

TUNGSTEN CARBIDE BALLS AND ROLLERS

Tungsten Carbide is commonly used in applications requiring extreme hardness, excellent wear resistance, and ability to withstand impact and shock. The durability of precision balls and rollers made from tungsten carbide makes it well worth the investment.
