GQZ 734449/10 Single Row Tapered Roller Bearing 220×340×76mm For Mining & Metallurgical Equipment

734449/10 is single row separable tapered roller bearing, consisting of inner cone assembly and outer cup. It can simultaneously withstand heavy radial load and one-way axial thrust. The pre-set contact angle ensures stable rotation and effective restriction of unidirectional axial movement. Components can be separated for convenient installation and maintenance. Widely applied in heavy-duty gearboxes, mining conveyors, metallurgical rolling equipment, large water pumps and medium-speed heavy-load rotating assemblies.

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