Functions of double row tapered roller bearings: Double row angular contact ball bearings can bear the combined radial and axial loads and torque loads mainly based on large radial loads, mainly used to limit the shaft and shell two-way axial displacement of the components. Such as: SKF double row angular contact ball bearings are similar in design to two single row contact ball bearings arranged back-to-back, but slightly narrower in width than two single row bearings. They are more rigid than single row bearings and can withstand overturning torque. The bearings are non-separable. It is widely used in the front wheel hub of cars (some models also use double row tapered roller bearings of the same size).

 

Double row tapered roller bearing role: tapered roller bearing has conical inner ring and outer ring raceway, tapered roller arranged between the two. The projection lines on all conical surfaces meet at the same point of the bearing axis. This design makes tapered roller bearings particularly suitable for bearing compound (radial and axial) loads. The axial load capacity of bearings is mostly determined by the contact Angle α. The larger the α Angle, the higher the axial load capacity. The Angle is represented by the calculated coefficient E. The larger the e value and the greater the contact Angle, the greater the applicability of bearing under axial load. Tapered roller bearings are usually separated, that is, a tapered inner ring assembly consisting of an inner ring with a roller and a cage assembly can be mounted separately from a tapered outer ring (outer ring). Tapered roller bearings are widely used in automobile, rolling mill, mining, metallurgy, plastic machinery and other industries.

 

Double row tapered roller bearing function: double row tapered roller bearing structure is various, the largest is 35000, there is a double raceway outer ring and two inner rings, two inner rings between a ring, change the thickness of the ring can adjust the clearance. These bearings can withstand both radial and bi-axial loads and limit axial displacement of the shaft and housing within the axial clearance of the bearing.
