N2  - Stability analysis of one-dimensional (long) partial slip texture journal bearing is presented. A journal bearing (one-dimensional) is analyzed considering slip on land, recess depth and extent of partial slip texture region. A modified dynamic Reynolds equation is based on theory of narrow groove approximation considering infinite cells (land with slip and recess configuration) in partial slip texture region. Pressure under static state and pressure gradients dynamic state due to journal center perturbation are derived considering Lundâ??s method (infinitesimally small perturbation of displacements and velocities). Load capacity and linearized dynamic coefficients are derived from integration of pressure (under static state) and pressure gradients (under dynamic state), respectively. The performance characteristics (stiffness (nondimensional) and damping (nondimensional) coefficients, threshold (critical) speed and critical ratio of whirl frequency) are presented based on partial slip texture configuration parameters. Stability threshold increases for both configurations of slip and texture at higher partial slip texture extent (angular) for low-to-medium eccentricity ratio bearing operating conditions. © 2021, Springer Nature Singapore Pte Ltd.
