30214 Single Row Separable Tapered Roller Bearing 70x125x24mm Truck Differential Construction Machinery Gearbox Equipment
The 30214 single row tapered roller bearing consists of separable inner cone assembly and outer cup, standard dimension 70×125×24mm. Its tapered roller and raceway structure can bear combined heavy radial load and one-way axial thrust simultaneously. Separable design allows independent installation of cone and cup, convenient clearance adjustment and maintenance. Widely used in truck differentials, construction machinery gearboxes, agricultural vehicle axles and heavy-duty transmission assemblies under mixed impact loads.
