Characteristics

Carbon Steel Ball: High hardness and cost-effective. Widely used in bicycles, bearings, pulleys, rails, and hardware. Magnetic and wear-resistant, often features oily packaging or electroplating (zinc, gold, etc.).

Chrome Steel Ball: Spherical rolling elements used in check valves, bearings, and rotary/linear motion devices. Known for precise outer diameter, surface roughness, and high tolerance.

Stainless Steel Ball: A key bearing component that maintains integrity at high temperatures. Offers exceptionally long service life under standard working conditions.

A

Product Application

Our steel balls are versatile and used in: cosmetics, automobile transmission parts, bearings, sliding rails, furniture rotating parts, electrical appliances, medical treatments, grinding, and counterweights.

Manufacturing Process

Heading: Wire is cut into short lengths and formed into spherical shapes between dies.

Deflashing: Removal of the ridge left by forming dies using heavy cast iron plates.

Soft Grinding: Precision is improved using a specialized grinding stone.

Heat-treating: Carburizing and hardening to achieve desired case depth and hardness.

Descaling: Removal of residues and by-products from the heat treatment phase.

Hard Grinding: Meticulous grinding to assure sphericity and tolerances within ±.0001".

Lapping: Proprietary processes to meet ISO 3290 Grade 10 - 48 requirements.

Finishing: Micro-smoothing for increased wear resistance and longevity.
