ABOUT US
Quality Control
At ITS BEARING, quality is not just inspected — it is built into every step of the manufacturing process. We implement a full-process quality control system, supported by advanced inspection equipment and strict international standards.
From raw material verification to final product release, each bearing undergoes multiple layers of inspection to ensure precision, reliability, and consistency.
Key Quality Control Equipment
To guarantee high performance, we utilize a wide range of precision instruments, including:
Roundness Testers
Ensure ultra-precise raceway geometry and minimize vibration and noise.
Surface Roughness Testers
Control surface finish to improve lubrication performance and bearing life.
Hardness Testers (Rockwell / Vickers)
Verify heat treatment quality and material strength.
Coordinate Measuring Machines (CMM)
Accurately measure critical dimensions and tolerances.
Noise & Vibration Testing Machines
Evaluate bearing running performance, especially for high-speed and precision applications.
Clearance & Internal Geometry Measurement Tools
Ensure correct internal clearance for optimal operation.
Metallographic Analysis Equipment
Inspect microstructure to guarantee material integrity and fatigue resistance.
Full Process Control
Our quality control process includes:
Incoming material inspection
In-process dimensional control
Heat treatment verification
Final inspection & performance testing
100% or sampling inspection based on application requirements
All processes are conducted under ISO-certified quality management systems, ensuring traceability and consistency.
Our Commitment
With advanced equipment and a skilled technical team, ITS BEARING delivers products that meet the highest standards for industries such as CNC machines, robotics, automotive, and heavy industry.
We don’t just supply bearings — we deliver precision, confidence, and long-term reliability.
