47678/47620 Single row tapered roller bearings compose of a outer ring and a inner ring with a group of conical roller sustained by basket shape cage. Outer and inner ring components can be separated, according to the rule of ISO conical roller bearing outline dimension standard,any conical roller bearing with standard model can be interchanged by it's inner or outer ring internationally.
Applications
In many applications tapered roller bearings are used in back-to-back pairs so that axial forces can be supported equally in either direction.
Pairs of tapered roller bearings are used in car and vehicle wheel bearings where they must cope simultaneously with large vertical (radial) and horizontal (axial) forces. Applications for tapered roller bearings are commonly used for moderate speed, heavy duty applications where durability is required. Common real world applications are in agriculture, construction and mining equipment, axle systems, gear box, engine motors and reducers.
