The figure below shows a cylindrical shaft of diameter D pulled through a cylindrical bearing of length Z at a constant velocity of V. The lubricant that fills the uniform gap h between the shaft and bearing is an oil having a kinematic viscosity of and a specific gravity SG. Assume the velocity distribution in the gap is linear. If D=37 mm; L = 0.6 m; h = 0.5 mm; V = 1.7 m/s; SG = 0.9; and 5.6 x 10 m/s, the force F required to pull the shaft is N. h Bearing Shaft Lubricant >AA V F SG h L
