Peugeot 405 bullhead bearing
The Peugeot bullhead bearing is a critical component in the front wheel assembly of vehicles like the Peugeot 405, Pars, and Samand. Its primary function is to support the front wheel and transfer rotational force from the axle to the wheel with minimal friction. Known as "bullhead" due to its distinctive internal shape within the front hub, this bearing features a double-row ball structure and precisely machined raceways to ensure uniform load distribution and extended service life. Made from hardened alloy steel and treated through heat processes, it offers excellent resistance to pressure, temperature, and high rotational speeds.
Technically, the bullhead bearing must be engineered with an inner diameter that fits precisely onto the shaft and an outer diameter that secures firmly into the hub, preventing any play or mechanical failure during operation. It is press-fitted into the front hub and designed to withstand both radial and axial loads simultaneously. Key features include tight tolerances, reliable internal lubrication, and dual-seal protection, all of which contribute to smoother operation with reduced noise and vibration. Selecting a bullhead bearing that meets OE standards and has been tested under real-world conditions is essential for enhanced vehicle stability,
