tapered roller bearing

2020-04-13

Tapered roller bearing bearings can be divided into single row, double row or four row tapered roller bearings according to the number of columns installed. Single row tapered roller bearings can withstand radial loads and axial loads in a single direction. When the bearing is subjected to a radial load, there will be an axial component force, which requires another bearing to withstand the axial force in the opposite direction to balance. Tapered roller bearings are the most used single row tapered roller bearings, in the car's front wheel on the use of a smaller size double row tapered roller bearings, four row tapered roller bearings are generally used in large cold, hot In large machines such as rolling mills. Here I will tell you about the general size of the tapered roller bearing model size.


Tapered Roller Bearings - Features

In the daily type of tapered roller bearing type is 30000, in the use of tapered roller bearings in GB/T 307.1-94 "rolling bearing radial bearing tolerances" involved in the size of tapered roller bearings, tapered roller bearings Between the outer ring and the inner component can be used 100% interchangeably. With the progress of society, the current outer diameter of the tapered roller bearing and the size of the outer raceway have been standardized with the same dimensions as the outer dimensions, and are not allowed to be changed during the design and manufacturing process. In this way, the tapered roller bearing outer ring and the inner component can be interchanged worldwide, which can greatly reduce the waste of the tapered roller bearing and the use price.

Tapered Roller Bearings - Category

Tapered roller bearings, which are more common in daily life, can be classified into single-row tapered roller bearings, double-row tapered roller bearings, and four-row tapered roller bearings. The single-row tapered roller bearing can be separated from the inner ring assembly on the outer ring of the structure. According to the ISO taper roller bearing outer-diameter standard, any standard type tapered roller bearing outer ring or inner ring assembly must be compatible with the same type. International interchange between outer ring or inner ring components. Under normal circumstances, the single-row tapered roller bearing outer ring raceway cone angle in the size range: 10 degrees -19 degrees, it can simultaneously withstand the combined effect of axial load and radial load. The larger the taper angle of a tapered roller bearing, the greater its ability to withstand axial loads.


Tapered Roller Bearings - Size Range

Tapered roller bearings of the conventional size range, single row tapered roller bearings: inner diameter size range: 20mm ~ 1270mm, outer diameter size range: 40mm ~ 1465mm, width size range: 15mm ~ 240mm. Double-row tapered roller bearings: The inner diameter ranges from 38mm to 1560mm, the outer diameter ranges from 70mm to 1800mm, and the width ranges from 50mm to 460mm. Four-row tapered roller bearing: The inner diameter size range is from 130mm to 1600mm, the outer diameter size range is from 200mm to 2000mm, and the width size range is from 150mm to 1150mm.

Tapered Roller Bearings - Mounting

Various types and structures of tapered roller bearings are similar in their installation. Xiao Bian has introduced the installation of four-row tapered roller bearings. First, the tapered roller bearings are installed into the bearing box. The bearing housing is journalled. The outer ring of the four-row tapered roller bearing and the bearing box are also assembled in a dynamic manner to fit the outer ring A into the bearing box. Tapered roller bearings are marked with characters on the outer ring, inner ring, and inner and outer spacers when they are shipped from the factory. They must be installed in the bearing housing in sequence according to the arrangement of the characters on the symbol. When all the parts are installed in the bearing housing during installation, then the inner ring and the inner ring, the outer ring and the outer ring are axially abutted against each other.


Tapered Roller Bearings - Applications

The bearing capacity of a tapered roller bearing depends on the raceway angle of the outer ring, and the size of the angle determines the bearing capacity of the tapered roller bearing. The number of rolling elements in the bearing is classified into single row, double row and four row tapered roller bearings. The single-row tapered roller bearing clearance needs to be adjusted by the user during use. Double-row and four-row tapered roller bearing clearances have been manufactured according to the requirements of the user when the product is shipped, and do not require user adjustment. Tapered roller bearings are mainly used in the automotive, mining, metallurgy, plastic machinery, machine and other industries.
