A natural-circulation pillow-block bearing with lyd 5 1 has a journal diameter D of 2.500 in with a unilateral tolerance of 20.001 in. The bushing bore diameter B is 2.504 in with a unilateral tolerance of 0.004 in. The shaft runs at an angular speed of 1120 rev/min; the bearing uses SAE grade 20 oil and carries a steady load of 300 lbf in shaft-stirred air at 70°F with a 5 1. The lateral area of the pillow-block housing is 60 in2. Perform a design assessment using minimum radial clearance for a load of 600 lbf and 300 lbf. Use Trumpler’s criteria.
