Heavy-duty trimetal connecting rod bearing set (OEM: 214950) engineered for Cummins NTA855 Big Cam platforms.
Constructed with a reinforced steel backing and tin-lead overlay to handle extreme mining vibrations in Komatsu D155 dozers, Kenworth W900 long-haulers, and Peterbilt 379 fleets.
Professional supply verified for heavy-load duty cycles.
For decades, the Cummins NT855 “Big Cam” has been the backbone of heavy industry. Keeping these legacy engines running requires bearings that can handle centuries of wear. Our Cummins NT855 connecting rod bearings are manufactured to precise OEM specifications (replacing 214950), offering a reliable lifeline for rebuilders working on classic International Transtar trucks or Komatsu D85 bulldozers.
Ruich Value understands that most 855 blocks in service today have seen multiple lifecycles. That’s why we specialize in supplying high-quality Copper-Lead Tri-Metal bearings not just in standard sizes, but in a full range of undersizes (.010″ to .040″). This ensures you can salvage ground crankshafts and extend the operational life of your heavy equipment without compromising on load capacity or durability.

A1: Symptom: Bearing material fatigue and shell deformation. Diagnosis: Big Cam NTA855 engines in mining or long-haul logistics experience high-frequency reciprocating force. Solution: The trimetal design of 214950 bearings allows the shell to deform slightly to fit the rod cap perfectly while the soft overlay handles the initial wear, ensuring the engine can operate continuously without bearing-related shutdowns.
A2: Technical Detail: We typically supply 214950 bearings in standard sizing. Pro-Tip: If your crankshaft journal has been ground (undersized), you must ensure the bearing thickness accounts for the material removed. Installing standard 214950 bearings on a ground-down crankshaft will cause zero oil clearance and catastrophic rod seizure.
A3: Diagnosis: Standard bimetal bearings often suffer from excessive surface wear in heavy-dust, high-torque mining environments. Solution: Our 214950 set utilizes an intermediate copper-lead layer which is significantly harder than standard babbit-only bearings, offering the necessary structural integrity for machines like the Komatsu D155 working in abrasive earthmoving conditions.
