Bearing systems used in the linear axes of industrial robots are subject to many design constraints. The table below compares three different trolley bearing systems using common design objectives. It can be seen from the table that the tandem bearing trolley is superior to the other two types. The unit structure trolley is an embodiment of the tandem bearing design. (Image Omitted) The unit structure trolley shown in Fig. 1 has the following features: 1. The stiffness of this trolley design can be changed to suit system requirements by varying the wall thickness (J) or the distance between adjacent bearings (K). 2. Each bearing 10 is supported by the walls of the trolley frame 12 which act as miniature cantilever springs.
