The camshaft bearing, code P50704-04, supports and guides the camshaft in the MAN L21/31 engine, enabling precise rotational movement required for accurate valve timing. Designed to handle the combined effects of radial loads, high-speed operation, and thermal expansion, this bearing ensures low-friction performance and extended engine life. Proper lubrication and high-quality material composition are essential for this component to minimize wear and preserve camshaft alignment over prolonged operation cycles.
