A modular base side bearing assembly has a cage with upstanding side walls defining a bearing cavity and a central bottom opening to receive a modular base on which a bearing element supported on a central base portion thereof. The modular base has externally visible tabs identifying a force level corresponding to the modular base, in which the thickness of the central base portion corresponds such force level. The modular bases are interchangeable with modular bases having central base portions of differing thickness, or zero-thickness, such that the same cage, bearing element, and wear cap can be used with different modular bases to provide different force levels. The modular base is movable vertically relative to the cage to accommodate uneven mounting surfaces. 1. A modular base and cage for a rail vehicle side bearing assembly , the modular base and cage comprising:a. a cage having upstanding side walls defining a bearing cavity, said cage having a central bottom opening; andb. a modular base interchangeably receivable in said central bottom opening, said modular base having a central portion, and said central portion defining a bottom surface of said bearing cavity.2. The modular base and cage of further comprising said modular base being vertically movable relative to said cage.3. The modular base and cage of further comprising said modular base having at least one identification portion externally visible of said cage when said modular base is assembled with said cage.4. The modular base and cage of further comprising said at least one identification portion exhibiting an indicator of a force level of said constant contact side bearing.5. The modular base and cage of wherein said indicator further comprises at least one of identifying text claim 4 , notches claim 4 , and colors.6. The modular base and cage of further comprising said modular base being captured within said cage when said cage and modular base are attached to said rail vehicle.7. The modular ...
