From Design to Finished Bearings
A complete bearing manufacturing workflow connects drawing review, material selection, precision machining, grinding, assembly, inspection, and final delivery to ensure reliable precision bearing solutions.
01
Technical Review
Review customer drawings and requirements to define the optimal bearing design and manufacturing process.
02
Raw Material Receipt
Before the raw materials enter the factory, they undergo material verification to ensure the hardness, corrosion resistance, and fatigue life of the bearings from the source, and refuse to recycle materials.
03
Precision Machining Workshop
CNC turning and precision grinding, stable control of surface smoothness, supporting sample to mass production.
04
Precision grinding
Apply advanced grinding techniques to achieve high precision, smooth surfaces, and consistent tolerances.
05
Assembly & Quality Inspection
Perform multidimensional testing before leaving the factory: radial clearance, noise, appearance, and dimensional review. Keep inspection records for each batch, support the provision of testing reports, and strictly control the defect rate.
06
Finished products and delivery
Finished products are stored by category, individually packaged, and support batch delivery. Orders are tracked throughout the entire process from stocking, quality inspection to packing, and delivered to global customers on time
