A new general formula is proposed to calculate the lubricant film thickness in the piezoviscous rigid lubrication regime. Equivalent radii ratio, load, speed, and material dimensionless parameters are included. New general criteria to decide whether piezoviscous rigid or EHD (elasto-hydrodynamic) or isoviscous elastic lubrication film thickness formulas have to be used are proposed. Comparisons with some other published results are made.
