Certification
Thanks to our extensive experience, our qualified and dedicated employees and the implementation of systematic quality management, we are able to ensure consistently high product quality and let our factory already got ISO SGS ROHS REACH certificates.
Quality Assurance
Our technical engineer has over 30 years experience . After finished to produce balls, we will take sample balls from the batch are sent for final audit to check for surface roughness, roundness, waviness, lot size variation and hardness in a sophisticated laboratory, according to specified control plans and dock audit procedures. Once all requirements are met, a test certificate is then prepared for the customer.
Customization
Plastic balls can be customized with non-standard specifications, or with hole design ,color customization and Size customization.
If you need to customize other products, please state your requirements or provide drawings. We will have professional engineers provide you with professional services to meet your requirements.
Silicon Nitride Ball
Silicon nitride balls are ceramic balls that are suitable for applications where high loads, high speeds and extreme temperatures are factors. Long life and the need for no lubrication makes this material very suitable for many applications. Silicon Nitride is anti-magnetic and resistant to corrosion by most substances.

Lightweight and Long Service Life: With only 40% of the density of steel, it reduces centrifugal force at high speeds, minimizing wear and extending bearing life.
High Hardness and Strength at Elevated Temperatures: Maintains excellent mechanical properties up to 1050 °C, with a hardness rating of HRC 78.
Self-Lubricating and Rust-Free: Operates reliably without lubrication and resists oxidation and rust in harsh conditions.
High Elastic Modulus: About 44% higher than steel, resulting in less deformation under stress.
Low Thermal Expansion: Its thermal expansion coefficient is just one-third of steel, providing better dimensional stability under temperature changes.
Thermal Shock Resistance: Withstands sudden temperature fluctuations without cracking or degrading.
Chemical Corrosion Resistance: Highly resistant to acids, alkalis, and most aggressive chemicals.
Non-Magnetic and Electrically Insulating: Suitable for use in magnetic-sensitive or electrically isolated environments.
No Reaction with Molten Metals: Remains stable and non-reactive at high temperatures in contact with molten metals.
Common Uses
Components for aerospace systems
Rolling and sliding elements in bearing units
High-durability parts for internal combustion engines
Tools and accessories for casting and metal processing
Structural parts in mechanical assemblies
