Service life and extension methods: ① Standard life: 8000-12000 operating hours (mineral oil, NAS 9 class, normal load); ② Extension measures: 1) Maintain oil cleanliness (NAS 9 class or higher--each class improvement extends life by 20%); 2) Avoid overload (operation at >300 bar reduces life by 50%); 3) Follow maintenance schedules (timely oil and filter changes extend life by 30%); 4) Ensure proper installation (coaxiality ≤0.05 mm prevents premature bearing wear); 5) Use genuine parts (counterfeit parts reduce life by 60-80%).
