In the current highly competitive automotive parts industry, Jielian Bearing in Jiaoxian, Shandong Province, takes intelligent and automated production as its core engine, establishing an industry-leading precision manufacturing system. With cutting-edge equipment and lean management, it defines the new height of "Shandong Made" automotive bearings.

Entering the production workshop of Jielian Bearing, 12 sets of CNC automated lines, 120 fully automatic grinding processing machines, 4 automatic bearing installation and assembly lines, 2 fully automatic bearing cleaning and rust prevention equipment, and 4 bearing rolling body production equipment are all operating efficiently. Combined with 4 bearing rolling body production equipment, a fully automated closed-loop production line from parts to finished products is formed. The highly intelligent production line not only significantly improves production efficiency and consistency, but also minimizes human intervention, ensuring that the precision, hardness, wear resistance and lifespan indicators of each set of bearings are stable and controllable.

The company has invested in building a professional bearing testing laboratory, equipped with a complete set of precision testing instruments, to conduct strict quality inspections on raw materials, semi-finished products and finished products throughout the process. From dimensional accuracy, clearance control, life testing to high and low temperature durability tests, each indicator follows an internal control system that is higher than national standards and those of the original equipment manufacturers. With the dual drive of "automated production + full-dimensional testing", Jielian Bearing products perform exceptionally well under high-load, long-term and complex working conditions, earning the trust of both original equipment manufacturers and the aftermarket.
