GT-SUITE offers best in class bearing modeling options, ranging from the very-fast running mobility method bearing suited perfectly for system level simulations to finite-element meshed bearings including the effects of cavitation, elasticity, and 3D journal tilt. These bearings can be easily integrated into system level models of cranktrains, valvetrains, oil systems and more. Additionally, there are dedicated models for thrust bearings and roller (ball/needle) type bearings.
