Bearing Type

At ordinary times more common tapered roller bearings can be divided into: single row tapered roller bearings, double row tapered roller bearings, four row tapered roller bearings. Single row tapered roller bearing outer ring in the structure can be separated and inner components, according to the provisions of ISO tapered roller bearings, tapered roller bearing outer ring or inner module of any standard model required between the same type outer or inner components is an international exchange. In general, the cone angle of the outer ring of single row tapered roller bearing is in the size range of 10 degrees -19 degrees, which can bear the combined action of axial load and radial load at the same time. The bigger the cone angle of the tapered roller bearing, the greater the axial load capacity.

Structure Characteristics

Tapered roller bearing type code is 30000, tapered roller bearings for the separation of bearings. Under normal circumstances, especially in the size range GB/T307.1-94 "rolling bearing radial bearing tolerances" involved in the tapered roller bearing outer ring and inner components are interchangeable with one hundred percent.

The angle of the outer ring and the diameter of the outer diameter of the outer diameter of the outer roller have been standardized. Not allowed to change in design and manufacturing. In order that the outer ring of the tapered roller bearing can be widely used in the world, the outer ring and the inner component can be exchanged.

Tapered roller bearings are mainly used to bear radial and axial load. Compared with angular contact ball bearing, the bearing capacity is large, and the limit speed is low. The tapered roller bearing can bear the axial load in one direction, and can limit the axial displacement of the shaft or the outer shell.

Main Application

Tapered roller bearings are mainly subjected to radial and axial load. Bearing capacity depends on the outer ring of the roller angle, the greater the bearing capacity of the angle of view. This type of bearing is divided into two types, according to the number of columns in the bearing, the number of columns is divided into single row, double row and four row tapered roller bearings. Single row tapered roller bearing clearance adjustment to users in the installation; double row and four row tapered roller bearing clearance has been in the factory according to user requirements given, the user does not have to adjust.

The tapered roller bearing is provided with a conical inner ring and an outer ring roller, and the tapered roller is arranged between the two. All projection lines on the cone surface are at the same point in the bearing axis. This design makes the tapered roller bearings especially suitable for bearing composite (radial and axial) loads. The axial load capacity of the bearing is mostly determined by the contact angle, the bigger the angle is, the higher the axial load capacity is. The E value is greater, the greater the E value, the greater the contact angle, the greater the applicability of the bearing under axial load.

Tapered roller bearings are usually separate type, that is, with the roller and cage assembly of the inner ring components of the inner cone assembly can be separated with the outer ring (outer).

Tapered roller bearings are widely used in automotive, rolling mill, mining, metallurgy, plastic machinery and other industries.
