In the high-stakes world of mining and power generation, bearing failure is not an option. Our Cummins KTA38 connecting rod bearings are engineered to support the massive combustion loads of the K-Series platform (19L, 38L, and 50L). Designed as a direct replacement for OEM 3016760 and 3055145, these parts provide the critical durability needed for 12-cylinder and 16-cylinder engines running 24/7 in Komatsu HD785 haul trucks and marine tugs.
Ruich Value utilizes a heavy-duty Copper-Lead Tri-Metal composition, essential for resisting seizure under the extreme torque of the QSK38 and KTA50 series. Whether you are overhauling a genset or maintaining a fleet of dump trucks, our bearings offer a verified, cost-effective alternative to genuine parts, ensuring your heavy equipment stays operational.
