Product Description

Sinotruk Engine Connecting Rod Bearing OEM Main Bearing Set VG1246030011/12

Ensure optimal crankshaft support, oil film stability, and long-term engine durability in your SINOTRUK commercial vehicle with this high-precision main bearing set, engineered as a direct-fit OEM replacement.

Product Overview

Designed for use in SINOTRUK's heavy-duty diesel engines, including the MC05, MC07, MC11, MC13, and D10 series, this main bearing set provides critical support for the crankshaft at each main journal. Manufactured to strict Chinese OE specifications, these tri-metal bearings deliver superior load capacity, fatigue resistance, and compatibility with high-pressure lubrication systems found in modern Euro III, IV, and V engines.

Ideal for engine overhauls, rebuilds, or replacing worn bearings due to low oil, debris, or extended service, this set ensures smooth operation, reduced friction, and protection against journal damage.
