Product Details
1. Precision Clearance for Smooth Operation
Designed to maintain the tight tolerances of diesel engines. A new bearing provides a standard radial clearance of 0.025-0.060 mm to ensure sufficient lubrication and prevent knocking .
2. Durable Wear-Resistant Alloy Construction
Features a high-strength steel backing coated with a soft, wear-resistant alloy (such as copper-lead or high-tin aluminum) to withstand heavy loads and protect the crankshaft journal .
3. Restores Lost Performance
Replacing a worn bearing (exceeding the wear limit of 0.20 mm) restores oil pressure, reduces knocking, and prevents potential catastrophic engine failure .
