​

• Specifiion

• Key functions

1.Friction Reduction: Eliminates metal-to-metal contact between the connecting rod and crankshaft, minimizing wear and improving engine efficiency (reduces fuel consumption by up to 2–3% in well-maintained systems).

2.Load Distribution: Spreads the extreme forces from combustion (up to 10 tons per cylinder in 3400-series engines) across the crankshaft journal, preventing localized damage.

3.Crankshaft Protection: The soft overlay wears first, avoiding scratches or scoring on the crankshaft journal – a repair that would require costly crankshaft grinding or replacement.

4.Engine Longevity: By maintaining a stable oil film and absorbing shocks, the bearing extends the service life of the connecting rod and crankshaft, reducing overall maintenance costs.
