L90 Fixed Timing Bearing
The fixed timing bearing for the L90 is a critical component of the vehicle’s timing system, primarily responsible for mechanically supporting the timing belt’s path in a fixed position without applying any adjustable tension. This bearing is typically made from high-quality alloy steel that has undergone heat treatment to provide the necessary resistance against mechanical pressure, wear, and the heat generated by engine operation. Its dimensions are precisely designed according to the technical standards of the L90 engine to ensure full compatibility with the timing system and related components, preventing any belt misalignment or vibration.
Structurally, the fixed timing bearing for the L90 usually features double-sided sealing to restrict the entry of dust, moisture, and contaminants into the bearing, which helps extend the product’s lifespan. Additionally, its internal lubrication is factory-applied and permanent, requiring no maintenance or oil replacement throughout its service life. The precise design of the balls and the retainer cage ensures smooth, quiet operation with minimal friction. High resistance to thermal and mechanical stresses is another key characteristic that makes this bearing a reliable and durable choice for the L90 timing system.
