Non-standard bearings are needed whenever standard catalogues fall short — special dimensions, clearance, temperature, contamination or materials. The value of customisation lies in precise matching of the actual duty. Hengtuo's process: requirement definition with load spectra and environment, design calculation of contact stress and life, rapid in-house trial using our own forging, turning, heat-treatment and grinding lines, on-machine validation, then volume production with frozen process files and SPC consistency control. We sell a full lifecycle of service, not just a bearing.
