Abstract

PURPOSE: To keep a sealing member free from the pressure fluctuation of pressure fluid, by reducing a clearance between inter and outer races of a ball bearing.
CONSTITUTION: A spacer 23, inserted between outer and inner races 21, 22 of a ball bearing 20, has holes for controlling the position of balls to play an additional role as a holder of the ball bearing. The difference between the clearance t1 of both races 21, 22 and the thickness t2 of the spacer 23 is very small. This gap t1-t2/2 is designed to reduce the pressure fluctuation produced in an annular groove 38 of the bearing 20 by throttling the passage, thus substantially eliminating the adverse effect of fluctuation on a Y-packing 14.
