Features:Tapered roller bearing type code 30000, tapered roller bearing for separating type bearing.In general, especially in the GB/T307.1-94 "rolling bearing centripetal bearing tolerance" involved in within the scope of the size of the tapered roller bearing outer ring and inner components is gm's one hundred percent can be used interchangeably.
The Angle of the outer ring and the outer raceway diameter size has the same size and appearance has standardized rules.Do not allow the changes in the design and manufacture.As to make the taper roller bearing outer ring and inner components are interchangeable common throughout the world.
Tapered roller bearing is mainly used to bear the joint mainly consisting of radial load and axial load.Compared with the angular contact ball bearing, large carrying capacity, limit rotational speed is low.Tapered roller bearings can withstand axial load in one direction, can limit axial displacement of shaft or housing in one direction.
Application :Tapered roller bearing mainly bear radial primarily diameter, the axial load.Bearing capacity depends on the Angle of the outer ring raceway, the greater the Angle of bearing.
The greater the load capacity.The separated type bearing is a bearing, according to the bearing the number of columns of the scroll body can be divided into single row, double row and four row circular cone roller bearings.Single row tapered roller bearing clearance to users in the installation adjustment;Double row and four row circular cone roller bearings clearance has according to user requirements for a given when the products leave the factory, not the user.
Have a conical taper roller bearing inner ring and outer ring raceway, the tapered roller are arranged in between.All projection line on the surface of the cone axis bearing the same points together.This design make the taper roller bearing is especially suitable for composite (radial and axial load.Bearing axial load capacity is mostly determined by the contact Angle alpha;Alpha Angle is larger, the higher axial load capacity.Angle size by calculating coefficient of e;E value, the greater the contact Angle, the greater the bearing axial load of the greater applicability.
Tapered roller bearings are usually separated type, that is, by inner ring with roller and cage components of cone inner ring components can be installed separately with cone outer ring (outer ring).
Tapered roller bearing is widely used in automotive, rolling mill, mining, metallurgy, plastics machinery and other industries.
