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 specification 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.

Formal quotation will be sent within 24 hours upon your inquiry.

Complete dimension drawings and load data available on request.

1. PX1 special internal profile, uniform stress distribution, outstanding shock resistance for excavator harsh working environment
2. Tapered raceway structure bears radial force and one-way axial thrust load simultaneously
3. Separable inner cone and outer cup support independent fitting and flexible preload control
4. Precision superfinished roller and raceway surfaces lower friction heat and operational noise under continuous heavy load
5. OEM interchangeable dimension, direct replacement for excavator travel motor aftermarket maintenance
6. Customizable options: OEM laser marking, high temperature resistant grease, special clearance grades

Effectively reduce roller fatigue wear and extend service life of excavator walking transmission assemblies.

• Komatsu PC400, Hitachi ZAX450, EX400 heavy excavator final drive travel gearbox
