The three core missions of bearings

Small parts, big role Although a bearing in a gearbox is only a small part of a huge system, it plays an indispensable role in any mechanical device that needs to rotate. The Municipal Airport Line project presented three new technical challenges for the bearings: Significantly higher operating speeds than conventional urban rail transit; Frequent starting and braking requirements during high-speed operation; The impact of fatigue and shock vibration on bearing performance.
