Abstract:
1. A railroad car constant contact side bearing assembly, comprising: a housing including upstanding wall structure defining an axis for said side bearing assembly; a non-metallic cap arranged for generally coaxial movement relative to said housing, with said cap having a generally flat upper surface and wall structure depending from said generally flat upper surface, with the wall structure of said cap combining with the wall structure of said housing to guide said cap for generally vertical reciprocatory movement during operation of said side bearing assembly; and with the generally flat upper surface on said cap extending beyond the wall structure of said housing; a spring accommodated within a cavity operably defined by the wall structure of said housing and the wall structure of said cap; a metallic insert maintained in operable association with the generally flat surface on said cap to slidably contact with an underside of said railcar whereby allowing said side bearing assembly to establish a coefficient of friction ranging between about 0.4 and about 0.9 with the railcar during operation of said constant contact side bearing assembly.
