Bearing and Steel Balls

Steel Balls for Bearings, Machinery and General Use

REDHILL supplies steel balls in AISI 52100, AISI 1010/1015 and AISI 1085 grades. Each grade offers a different balance of hardness, wear resistance and cost. Therefore, choose the steel to match the load, speed and working conditions in your system.

Applications of Steel Balls

Bearings

Steel balls roll between the rings of ball bearings. As a result, they help reduce friction and carry loads during rotation. In addition, accurate size and a smooth surface help the bearing run consistently.

Automotive Components

Automotive manufacturers use steel balls in transmissions, steering assemblies and selected suspension components. For example, balls serve in bearings and locking mechanisms within these systems. Therefore, the steel grade and hardness must suit the specific part.

Industrial Machinery

Steel balls also serve in couplings, guides and other moving parts. In addition, the choice of steel and heat treatment helps match the ball to the task. However, lubrication and surface finish also affect wear and service life.

Consumer Products and General Use

Manufacturers use carbon steel balls in locks, tools, toys and household products. For example, common uses include drawer slides and casters. In these applications, the choice of grade helps balance cost and durability.

Steel Grades and Precision Options

  • AISI 52100: Through hardening gives this chromium alloy steel high hardness and wear resistance. Therefore, it suits precision ball bearings and other wear parts.
  • AISI 1010/1015: Low-carbon steels offer options for general use. For example, case hardening creates a hard surface while the core remains softer.
  • AISI 1085: This high-carbon steel supports through hardening for parts that need hardness and wear resistance.

See our precision grade guide for tolerances. In addition, specify the surface finish and material condition your application requires.

Finally, send REDHILL your ball diameter, quantity, steel grade and working conditions. We can then confirm suitable options, lead time and worldwide shipping.
