NTN-SNR crankshaft bearing

An advanced Rolling Bearing for Automotive engine proven to reduce friction and CO2 emissions.


This automative crankshaft rolling bearing has no NVH (Noise, Vibration, and Harshness) impact while keeping a high reliability feature.

Experts estimates that 25% of energy used to move a car is lost due to internal friction. Part of this energy is lost during crankshaft rotation, a core part of the Internal Combustion Engine (ICE). To support the crankshaft, "plain bearings" are used, in other words a thin oil layer under high flow and high pressure. Oil shearing and pressure generation are root causes of the losses. NTN-SNR Rolling Bearing for crankshaft reduces both losses, saving about 100 kg CO2 emission for each car equipped.
