Peugeot 405 fixed timing bearing
The fixed timing bearing for the Peugeot 405 is a vital component within the engine’s timing system, responsible for maintaining the precise positioning of the timing belt along its path. Unlike tensioner or idler bearings, this bearing does not apply adjustable pressure to the belt and functions in a stationary manner. It is typically constructed from hardened steel with high resistance to friction and elevated temperatures, ensuring reliable and consistent performance over time. The precision-engineered design of this component helps reduce noise and vibration during engine operation and prevents any disruption in the synchronization between the crankshaft and camshaft—an essential factor for optimal combustion efficiency and mechanical safety.
From a technical standpoint, the fixed timing bearing used in the Peugeot 405 is usually manufactured to standard dimensions and is fully compatible with TU5 and XU7 engine timing systems. This bearing must withstand high temperatures, provide effective lubrication, and feature proper sealing to avoid damage or performance loss under harsh operating conditions. Its service life is heavily influenced by the quality of its materials, manufacturing precision, and correct installation. Therefore, using certified, high-quality bearings
