The film thickness was measured by the film measurement system of slide bearing under the conditions of different loads and different speeds at a fixed angle and fixed oil supply.The dimensionless carrying capacity curve and friction coefficient curve were obtained and compared with the theoretical curve.The results show that the capacity is increased first and then decreased along with the increasing of gap ratio,and the capacity value reaches the maximum near at the gap ratio of 12.When the gap ratio is less than 1,the friction coefficient is increased along with the decreasing of gap ratio,and when the gap ratio is constant,the load has no influence on the friction coefficient.
