All you need to know about Inch Tapered Roller Bearings
The ability of single row tapered roller bearing to bear axial load depends on the contact angle, that is, the angle of the outer ring raceway, the greater the axial load capacity. The most widely used tapered roller bearings are single-row tapered roller bearings. Small size double-row tapered roller bearings are used in the front hub of the car. Four-row tapered roller bearings are used in heavy-duty machines such as large cold and hot rolling mills.
Tapered roller bearings type code 30000, tapered roller bearings for the separation of bearings. In general, especially in GB/T307.1-94“Rolling bearings, radial bearing tolerances” referred to the size range between the outer ring and inner components of tapered roller bearings is 100% interchangeable use.
The angle of the outer ring and the diameter of the outer raceway have been standardized to the same size as the outer dimensions. It is not allowed to be changed during design and manufacturing. Thus, the outer ring and inner assembly of tapered roller bearings can be interchanged worldwide.
Tapered roller bearings are mainly used to bear radial and axial combined loads. Compared with angular contact ball bearing, the bearing capacity is large and the limit speed is low. Tapered roller bearings are capable of withstanding axial loads in one direction and of limiting axial displacement in one direction of the shaft or housing.
A single row tapered roller bearing has an outer ring, an inner ring, and a group of tapered rollers comprising an inner ring assembly contained in a basket cage. The outer ring can be separated from the inner ring assembly, in accordance with the ISO standard for tapered roller bearings, any standard tapered roller bearing outer ring or inner ring assembly shall be internationally interchangeable with the same type of outer ring or inner ring assembly. The outside dimension and tolerance of the same type of outer ring should be in accordance with ISO492(GB307). The cone angle and the cone diameter of the inner ring assembly should also be in accordance with the interchangeability regulations.
Generally, the cone angle of the raceway of the outer ring of single row tapered roller bearings is between 10 ° and 19 °, which can bear both axial and radial loads. The larger the cone angle, the greater the capacity of bearing axial load. Large cone angle bearing, code plus B, cone angle between 25 ° ~ 29 °, it can bear a larger axial load. In addition, single-row tapered roller bearings can be installed during the adjustment of the size of the clearance.
The outer ring (or inner ring) of double row tapered roller bearings is an integral whole. Two inner rings (or outer ring) small end face close to the middle of the ring, clearance is to rely on the thickness of the ring to adjust, can also be used to adjust the thickness of the ring double row tapered roller bearing pre-interference.
Four rows tapered roller bearings, this bearing performance and double row tapered roller bearings basically the same, but then double row tapered roller bearings to bear the radial load, the limit speed is slightly lower, mainly used in heavy machinery.
Inch tapered roller bearings differ from metric bearings in structure, assembly size, and rotation accuracy. Mostly used in import machinery or special needs industries.
The bearing has four rows of rollers, can withstand extreme radial load, and can withstand two-way axial load, the limit speed is low. It is widely used in various cold and hot rolling mills. The inner diameter of the bearing and the roll diameter adopt the transition fit. The axial clearance has a great influence on whether the tapered roller bearing can work normally or not. When the clearance is too small, the temperature rise is higher, therefore, special attention should be paid to the installation of three outer rings, two inner rings, two outer rings, one inner ring of the factory type number, do not install the wrong.
Four rows of a tapered roller bearing are one of the main roller bearings. The radial and axial load capacity of this kind of bearings are larger than that of single-row bearings. It can limit the axial displacement of two directions of the shaft (or housing) in the range of axial clearance, so it can be used for two-way axial positioning. The radial and axial clearance of the bearing can be adjusted by changing the thickness of the spacer between the inner and outer rings.
Four-row tapered roller bearings are mainly used for the work rolls of hot and cold rolling mills, as well as the rolls of cogging mills. Due to the requirement of convenient loading and unloading, usually with the gap into the neck of the roller. Tapered roller bearings generally use steel plate stamping cage, larger size, the use of pillar cage.
