A tapered roller bearing main bear with radial primarily, the axial union load. Bearing outer ring rolling bearing capacity depends on the way Angle, the greater the carrying capacity of the larger Angle. This type of bearings is bearing separation, according to the bearing of the roller column number into a single, double row and four-row circular cone roller bearings. The single row circular cone roller bearing clearance to users in the installation to adjust; Double-row and four-row circular cone roller bearings clearance has set up a file in the products based on user requirements given, don't need to adjust by the user.
Tapered roller bearings taper inner ring and outer ring have a groove, the tapered roller is arranged in between. All of the surfaces of the cone of lines in the projection of bearing the same point axis together. This design makes circular cone roller bearings is especially suitable for bear composite (radial and axial) the load. The bearing axial load ability is the contact Angle α of the decision; Larger Angle α, axial load capacity is higher. Angle size by calculating coefficient e to say; E value is, the bigger the contact angle is, the bigger the axial load bearing of the greater the applicability.
Tapered roller bearings are usually separated model, namely the belt roller and maintains a component of the inner circle, the circle of inner cone components and cone outside (outer) can apart installation.
Tapered roller bearings widely used in the automotive, rolling mill, mining, metallurgical, plastic machinery, etc
