Commercial & Industrial Applications

Traditionally, industries used plastic and ceramic balls for their operations. However, the introduction of high-quality steel balls has been a game changer as they offer better strength, hardness, and toughness. Most steel balls are electrically conductive or can be magnetized. Other types of metal alloy balls can provide corrosion and refractory resistance.

These features make steel balls versatile in many applications, ranging from supporting conveyor belts to enhancing the efficiency of manufacturing processes in commercial and industrial applications. Here’s an overview of the applications of steel balls in various commercial and industrial spaces.

  • Bearings

    Bearings

    Small metal balls make up various types of bearings, such as deep groove ball bearings, angular contact bearings, and thrust bearings.

  • Conveyor Systems

    Conveyor Systems

    Conveyor systems use steel balls to facilitate the movement of materials in manufacturing, logistics, and warehousing facilities.

  • Casters

    Casters

    Casters are the swiveling wheels often found on furniture, carts, and other objects to make them easier to move. Ball bearings are small, round metal balls that reduce friction and enable smooth rotation. When ball bearings are incorporated into caster wheels, they allow for easy and smooth movement in all directions, making it simple to maneuver objects.

  • Precision Instruments

    Precision Instruments

    Steel balls are used to manufacture precision instruments such as gauges and coordinate measuring machines.

  • Manufacturing Machinery

    Manufacturing Machinery

    Steel balls play a role in various manufacturing machinery, including punch and die sets, which aid in the precision cutting and shaping of materials.

  • Robotics

    Robotics

    Steel ball bearings are essential for precise and controlled movement in robotic welding, assembly, and material handling tasks.

  • Agitator Balls

    Agitator Balls

    Sometimes called mixing balls or mixing beads, agitator balls are small spherical objects placed inside aerosol spray cans or other liquid containers. Their primary purpose is to aid in the thorough mixing and dispersion of the contents when the container is shaken before use. These agitator balls are typically made from materials like stainless steel or glass, which are resistant to corrosion and do not react with the contents of the container. They are also sized appropriately to fit within the container’s neck or opening without causing blockages. Here’s how they work and their purpose:

  • Mixing

    Agitator Balls

    Mixing

    Spray can agitator balls are designed to move freely within the container. When the can is shaken, these balls bounce around and create turbulence inside, helping to break up clumps, disperse settled particles, and mix the contents thoroughly. This ensures that the product being dispensed (such as paint, spray adhesive, lubricant, or cosmetic product) maintains a consistent and uniform composition.

  • Preventing Clogging

    Agitator Balls

    Preventing Clogging

    In certain aerosolized products, such as paints or coatings, particles can settle over time and lead to clogs or uneven spray patterns. Agitator balls help prevent clogging by continuously agitating the contents, ensuring that they are well-mixed and ready for application.

  • Product Performance

    Product Performance

    Proper mixing and dispersion of ingredients are crucial for the performance and effectiveness of many liquid or semi-liquid products. Agitator balls help maintain product quality and consistency.

  • User Convenience

    User Convenience

    For end-users, the presence of agitator balls makes it easier to prepare and use the product. Shaking the container ensures that the product is ready for application without the need for additional mixing or stirring.

Automotive Industry

Steel balls can withstand high pressure and heat, so they are used in the automotive industry to ensure smooth and reliable vehicle performance. Their durability and toughness make them the perfect choice for parts such as constant velocity (CV) joints and bearings.

The following are examples of how they work on various vehicle components.

Automotive Industry

Bearings

Steel balls are used in various types of bearings throughout vehicles. These bearings handle thrust and radial loads in critical car parts such as the wheel, engine, and transmission system.

Automotive Industry

Constant Velocity (CV) Joints

CV joints use steel balls to transfer power smoothly from the drive shafts to the wheels and transmission, enabling flexibility and a wide range of motion in the steering and suspension systems.

Automotive Industry

Ball Joints

Ball joints connect the control arms to the steering knuckles and are crucial for precise steering control. Steel ball bearings are used in these joints to enable responsive steering.

Medical Industry

In the medical industry, steel balls are valued for their durability and resistance to high heat and pressure. Here are some of the specific applications of steel balls in this industry:

Grinding Media

Steel balls are used as grinding media for manufacturing powders and medications, creating consistent particle sizes. Steel balls can also function as agitators in certain products.

Medical Equipment

Medical equipment such as MRI machines and dental instruments use small metal ball bearings to ensure smooth and precise movements during operations.

Dispensing Mechanisms

Steel balls are used as part of a ball mechanism in drug dispensers and inhalers to move products up through tubes or packaging. This helps deliver accurate doses.

Gas Delivery Systems

Medical gas delivery systems have ball valves with steel balls, which help to ensure precise control of gas flow in oxygen and anesthesia equipment.

Orthopedic Implants

Certain orthopedic implants, such as hip and knee replacements, use steel ball components that fit into sockets to provide articulation and movement.

Defense and Military Industry

Steel balls are used in the manufacturing of defense and military equipment such as missile guidance systems, weaponry, tanks, protective wear, and more. Common applications include:
  • Shotgun Ammunition Shotgun Ammunition Shotgun Ammunition
    Shotgun charges consist of steel ball bearings that are fired out of a smooth bore weapon. Shotgun charges are commonly made of carbon steel and plated with copper and zinc. This replaces the old method of using lead charges, as shotguns are commonly used in hunting applications, and lead is poisonous. Using carbon steel also increases the shelf life of the charge. Our balls are commonly used in 12-gauge or 16-gauge shotgun shells.
  • Ballistic Protection Ballistic Protection Ballistic Protection
    Steel balls or steel plates are incorporated into armored vehicles, tanks, and personal body armor to provide protection against small arms fire and shrapnel.
  • Explosive Devices Explosive Devices Explosive Devices
    Steel balls may be used in the triggering mechanisms or fuses of explosive devices, ensuring that they function as intended.
  • Ballistic Testing Ballistic Testing Ballistic Testing
    Steel balls are used in ballistic testing to assess the performance and durability of various defense materials, including body armor, vehicle armor, and protective structures.
  • Calibration Calibration Calibration
    Steel balls are used as reference standards for calibrating testing equipment and instruments used in the defense industry. Ensuring accurate measurements is crucial for the development and testing of defense systems.
  • Aerospace Applications Aerospace Applications Aerospace Applications
    Steel balls are used in aerospace applications, including guidance systems, actuators, and various components in aircraft and spacecraft.
  • Electronics & Sensors Electronics & Sensors Electronics & Sensors
    In some military and defense electronics, steel balls may be used as part of switches, connectors, or sensors.
  • Gears & Mechanical Systems Gears & Mechanical Systems Gears & Mechanical Systems
