As a trusted B2B bearing manufacturer and supplier in China, we understand the critical importance of precision and quality in the bearing industry. To further improve our quality assurance process and meet the highest international standards, our factory has recently introduced a Fully Automatic Bearing Clearance Measuring Machine — a cutting-edge advancement in bearing inspection technology.
Bearing clearance, also known as internal clearance, refers to the total distance through which one bearing ring can be moved relative to the other, either in a radial or axial direction. It directly affects bearing noise, vibration, heat generation, and lifespan.
Accurate clearance control is essential for:
Ensuring proper fit and preload
Reducing vibration and noise in machinery
Improving performance in high-speed or heavy-load applications
Extending bearing life in demanding environments

Our newly deployed equipment brings the following benefits:
✅ High Precision Measurement
Capable of detecting radial and axial clearance with micrometer-level accuracy, meeting or exceeding international standards such as GB/T 4604 and ISO 1132.
✅ Full Automation
The machine supports non-contact, automatic positioning and measurement, significantly reducing human error and improving repeatability.
✅ Real-Time Data Output
Measurement results are recorded and displayed in real time, and can be exported to quality control systems for data traceability and analysis.
✅ Fast and Efficient
High-speed detection allows for 100% inspection in mass production, ensuring consistent quality with reduced labor cost.
✅ Adaptable to Various Bearing Types
Compatible with products from the tapered roller bearing stockist, deep groove ball bearings, cylindrical roller bearings, and more.
By implementing this advanced clearance testing technology, we are able to guarantee:
Consistent product performance
Enhanced reliability under extreme working conditions
Better support for industries such as mining, automotive, wind energy, and heavy machinery
Whether you're sourcing standard-size bearings, such as metric tapered roller bearings, or custom-engineered solutions, our commitment to precision manufacturing and strict quality control gives you the confidence to trust our precision automotive bearings.
At DSBR automobile bearing factory, we continuously invest in modern inspection equipment and lean manufacturing systems to ensure every bearing meets the performance and durability requirements of your market.
