Learn About Ball Bearing’s Manufacturing Process

Have you wondered how ball bearings are made?

Watch a video to get an intuitive look at the full process from raw materials to finished products：

Material Selection: Answering “what are ball bearings made of?” Most use high-carbon chromium steel for hardness and wear resistance. For special needs, stainless steel (corrosion-resistant) or ceramic (high-temperature) ball bearings work. Raw material quality is critical.

Forging & Shaping: Steel is heated, forged into rough inner/outer rings and balls, then machined to basic sizes—key for structural integrity.

Heat Treatment: Parts are heated, quenched (hardened), then tempered to reduce stress—vital for long-lasting ball bearings.

Grinding: Multi-stage grinding hones parts to micron-level precision, ensuring smooth operation.

Assembly: Done in clean rooms to fit rings, balls and cages—no misalignments allowed.

Lubrication: Grease or oil is used to cut friction and block contaminants.

Quality Testing: Inspections, dimension checks and performance tests ensure compliance.

Ball bearings are used in autos, industrial machines, household appliances and aerospace.

GQZ bearing strictly adheres to every step of the above manufacturing process—even adding extra quality checks for raw material purity and post-assembly performance.

It uses advanced grinding technology to achieve ultra-tight tolerances,offers customized solutions for special scenarios (like high-load industrial machinery or corrosion-prone marine equipment), and all its products meet ISO 9001 standard.

Whether for automotive transmission systems, precision machine tools or home appliance motors, GQZ bearing delivers durable, high-performance options that stand out in reliability.
