Industry Challenges
Fluid Challenges in Key Components Manufacturing
Downstream industries such as high-end equipment, NEVs and robotics are raising the bar for precision, life and consistency of basic components. With 30 years of industrial-media expertise and R&D capability certified by COMAC and airworthiness authorities, Kerun delivers tailored high-quality solutions "from formulation to shop floor", helping every component withstand extreme working conditions.
Surface consistency and defect control
High-end bearings and precision gears require strict control of surface burn, residual stress and defects—inconsistent cooling or insufficient cleanliness of media directly raises early-failure risk.
Cost-quality balance in mass production
Mass production of bearings and fasteners is highly sensitive to media stability, life, consumption and maintenance cost—frequent changes and maintenance significantly compress profit margins.
