about Aosen
Your Reliable Bearing Manufacturing PartnerServing global markets, we offer overseas clients one-stop solutions covering customized production, quality control, stable supply, and export support.





We offer end-to-end, one-stop customization services for non-standard bearings. Supported by our own manufacturing facility, we maintain full control from raw material sourcing to final delivery. Bearings can be developed based on customer drawings or samples, with structural and dimensional adjustments such as extended inner rings, grooved outer rings, and special tolerance requirements to suit specific operating conditions.
A comprehensive, process-wide quality control system is in place to ensure precision and consistency. Using specialized inspection and measurement equipment, we closely monitor critical parameters including inner and outer diameters, as well as roundness. All bearings undergo standardized factory inspections—covering flatness and visual quality—before shipment, effectively preventing defects and ensuring reliable performance.
We have established a dual-layer product portfolio combining proprietary core models with extended model options, serving bearing applications across multiple industries. Our own factory supplies 40 proven mainstream models with stable availability, while partnerships with five qualified manufacturers expand the range to over 230 models, covering non-standard customization, special materials, and high-precision bearings.
Our factory focuses on large-scale production of deep groove ball bearings, with an annual output of 13–15 million sets, ensuring secure and on-time delivery for high-volume orders.
Direct supply from our own factory reduces intermediate costs while maintaining consistent quality and competitive pricing. By collaborating with five specialized partner factories, we broaden product coverage and improve overall efficiency, enabling flexible procurement solutions with strong cost advantages.
