Lubrication Management Expert

Total Excellent Lubrication (TEL) is a lean management model centered on equipment reliability, achieving cost reduction and efficiency improvement through optimized lubrication processes. Originated from Nippon Steel and adopted by U.S. manufacturing, TEL addresses critical industry challenges: over 75% of hydraulic system failures and 80% of gear wear are lubrication-related. Implementation can reduce lubrication-related failures by up to 90% while significantly enhancing overall production efficiency.

TEL delivers substantial economic benefits globally. At Nippon Steel's Nagoya Plant, bearing procurement dropped 50%, hydraulic pump replacements fell 80%, and lubricant consumption decreased 83%. A struggling U.S. steel mill became the industry's most profitable after adopting TEL. In China, Delong steel achieved nearly 100 million RMB in direct benefits over three years, while Delong Steel ranked top in profitability among private steel enterprises.

Implementing TEL involves seven key steps: training and skill development, on-site assessment, benchmarking and gap analysis, lubrication system consulting, contamination control, oil analysis monitoring, and data-driven maintenance management. Oil analysis serves as the "navigation radar," while contamination control is prioritized—together enabling predictive and proactive maintenance strategies.

TEL drives maintenance transformation from reactive and scheduled repairs to condition-based predictive and proactive maintenance. EPRI research shows predictive maintenance can reduce costs by 47% compared to reactive approaches. Lubrication management becomes central to equipment reliability, enabling fundamental shifts from loss to profitability.
