Abstract: The cage is a crucial component of the bearing. It not only evenly separates the rolling elements but also
influences the redistribution of lubricant within the bearing. The sliding contact between the cage and the rolling element
leads to energy loss due to friction. Friction and wear are inevitable; however, friction can be minimized by altering the
contact conditions between the rolling elements and the cage. Therefore, this study aimed to experimentally investigate
the sliding friction between the rolling element and the cage under various spatial positions and structural variables. To
achieve this goal, a cage simulation unit with free movement and displacement had been designed and installed on a ball-
on-disc testing machine. This setup allows for the measurement of the cage in different spatial positions, and the cage
simulation unit could accommodate various types of cages for experimentation, providing a range of data references for
the interaction between the rolling element and the cage. The test results indicated that the design of the cage has a
significant impact on the performance of the grease-lubricated bearing. It had been determined that the rolling element
speed, cage position, cage height, and the clearance between the rolling element and the pocket were the primary factors
affecting the sliding friction of the ball cage. By varying the rolling element speed, it was observed that the speed
