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.

• Separable cone & cup structure, easy separate mounting and clearance fine-tuning during assembly
• Tapered matching design undertakes radial and one-way axial composite load at the same time
• Crowned tapered rollers reduce edge stress, resist impact and vibration for harsh working conditions
• High-hardness quenched steel components offer outstanding wear resistance and long service life
• Standard universal size fully interchangeable with global mainstream replacement parts
• Matched paired double sets can be supplied for bidirectional axial load requirements

This separable 30214 tapered roller bearing is widely matched to:

• Light/medium truck drive axle differentials, wheel hub rotary support assemblies
• Excavator, loader construction machinery gearbox and transmission shafts
• Large agricultural tractors, harvester drive and steering axle parts
• General industrial heavy speed reducers, mining auxiliary transmission equipment
