5p-1948-5p-1949 Single Row Tapered Roller — Cat 776D 777G

This is a single-row tapered roller bearing designed to reduce friction and support axial and radial loads within an engine's rotating assembly. It is manufactured to meet stringent OEM quality standards, ensuring superior durability and performance compared to worn bearings that exhibit increased play and heat generation. Operators may notice increased engine noise, reduced power output, or abnormal heat from the bearing area when this component begins to fail.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

Initial signs of failure may include a distinct humming or grinding noise from the engine, especially under load. If ignored, the bearing can seize, leading to significant power loss and potential damage to adjacent rotating components. Continued operation with a failing bearing risks severe internal engine damage.

Installation Tip

Ensure the bearing housing is meticulously clean before installation to prevent contamination. Avoid using excessive force or improper tools when seating the bearing, as this can damage the delicate roller surfaces.

Service Note

Inspect the bearing race for wear or damage and ensure the crankshaft or camshaft journal is smooth and free of scoring.
