Our Manufacturing & Quality Control Capabilities

From raw materials to finished bearings – here's how we ensure quality at every stage.

Advanced Heat Treatment Process

We use controlled atmosphere heat treatment lines to ensure consistent hardness and depth of the bearing raceways for extended fatigue life.

Precision Grinding Line

Our CNC grinding machines maintain tight tolerances on dimensions, roundness, and surface finish, achieving precision grades from P0 to P5.

100% Flaw Detection

Every batch is tested using magnetic particle inspection (MPI) to detect surface and sub-surface cracks, ensuring the structural integrity of every component.
