GQZ CR6016PX1 Single Row Tapered Roller Bearing 300×380×38mm For Excavator Travel Motor Final Drive
CR6016PX1 is a large-size single row separable tapered roller bearing, original specifiion for medium & large excavator final drive travel assemblies. PX1 stands for optimized internal geometry specially developed for heavy impact working conditions. It can simultaneously sustain heavy radial load and unidirectional axial thrust load. Separable cone and outer cup structure simplifies installation, disassembly and preload adjustment. Widely applied on PC400, ZAX450, EX400 and similar heavy excavator walking gearboxes.
