Year on Year PROTEC has improved Cp/CpK Indices across all critical manufacturing processes, including cold forging, heat treatment, and precision grinding. That's why global bearing OEMs trust PROTEC for consistent quality, zero-defect performance, and reliable delivery of ready-for-assembly taper rollers.
PROTEC tapered roller is tube-packed with rigid plastic tubes before dispatch, ensuring that precision-ground surfaces, factory-applied lubrication, and dimensional integrity are fully preserved from our facility to your assembly line.
Key Applications:
PROTEC operates under IATF 16949 and ISO 9001 certified quality management systems across manufacturing operations. These certifications demonstrate disciplined process control, documented traceability and continuous improvement aligned with automotive standards.
This includes real-time SPC monitoring, dimensional verification, eddy-current testing, and camera-based visual inspection to ensure consistent roller geometry and surface integrity.
Every PROTEC roller is tracked with complete digital traceability from raw material heat lot through cold forging, heat treatment, grinding, inspection, and final packaging. At IATF 16949 compliance standards, full batch records enable supplier audits, root-cause analysis, and zero-defect accountability.
