Identification

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.
