1/8" Steel Balls Grade 40 (Pack of 1200) – Precision and Reliability for Every Application
Discover the perfect combination of strength, precision, and durability with these 1/8 inch (3.175 mm) Grade 40 steel balls, crafted to meet the needs of professionals and hobbyists alike. Manufactured from high-quality hardened carbon steel, these balls deliver consistent size, exceptional roundness, and a smooth polished surface that ensures reliable performance in a wide range of mechanical and industrial uses.
Engineered for Precision
Grade 40 steel balls conform to industry standards (ISO 3290) with tight tolerances, guaranteeing minimal deviation in diameter and roundness. This precision translates to smoother operation, reduced vibration, and enhanced efficiency in any mechanical system where they are deployed.
Robust Material and Finish
Constructed from hardened high-carbon steel, these balls offer excellent resistance to wear and deformation under load. The polished finish reduces friction and noise during operation, extending the lifespan of components such as bearings, gears, and actuators.
Versatile Applications
Bearings and Motion Systems: Ideal for ball and roller bearings, enabling smooth rotation and linear motion.
Automotive Repair & Manufacturing: Perfect for CV joints, gearboxes, and steering components requiring consistent, durable steel balls.
Industrial Machinery: Use in valves, conveyor rollers, cams, and other moving parts subject to repeated stress.
Robotics and Automation: Ensure precise motion and control in robotics joints and linear guides.
Hobby and DIY Projects: Suitable for mechanical prototypes, slingshot ammo (check legality), and custom machinery.
Bulk Packaging for Efficiency
The pack contains 1200 pieces, providing a generous supply for maintenance, manufacturing, or large-scale projects. This makes it ideal for workshops, factories, and enthusiasts who value quality and quantity.
Handling and Storage Tips
Store in a dry environment to prevent rusting since these are not stainless steel.
Handle with care to maintain the polished finish — use gloves or tools to avoid skin oils causing oxidation.
Consider applying a rust inhibitor if used in environments prone to moisture.
