Caterpillar Main Bearings Protect Against Costly Engine Failures
Caterpillar main bearings support the crankshaft and allow it to rotate smoothly within the engine block, absorbing the forces generated by combustion and ensuring consistent, low-friction operation. Each bearing set is precision-engineered for specific CAT engine models, including 3116, 3128, 3406, C11, C13, C15, 3508, 3512, 3516, D353, D398, and many more. These bearings are available in standard sizes and a range of undersized options (such as 0.25mm, 0.50mm, 0.51mm, 0.7mm), allowing for proper fit even after machining or wear on the crankshaft journals.
Constructed from tri-metal, steel-backed aluminum, or similar robust materials, high quality replacement main bearings for Caterpillar equipment are designed for high load capacity, heat resistance, and long service life helping prevent premature crankshaft wear and engine failures. Correct installation, lubrication, and regular inspection are essential to maintain proper bearing clearance and oil pressure.
Propel Parts supplies a comprehensive range of high quality replacement main bearings for Caterpillar equipment, with clear compatibility listings and fast shipping. This ensures you can quickly find and install the correct bearing set for your engine, minimizing downtime and protecting your investment.
