Tapered roller bearings are separable bearings, and the inner and outer rings of the bearings have tapered raceways. This type of bearing is divided into single row, double row and four row tapered roller bearings according to the number of rows of rollers installed. Single row tapered roller bearings can withstand radial load and axial load in a single direction. When the bearing bears radial load, an axial component will be generated, so when another bearing that can bear the axial force in the opposite direction is needed to balance.
Inch series tapered roller
In tapered roller bearings, in addition to the metric series, there are also inch series. Inner ring components and outer rings of inch series bearings other than four-row tapered roller bearings have their own codes.
Double row tapered roller bearings
Paired double tapered roller bearings and double row tapered roller bearings
In tapered roller bearings, in addition to the metric series, there are also inch series. Inner ring components and outer rings of inch series bearings other than four-row tapered roller bearings have their own codes.
Double row tapered roller bearings
Paired double tapered roller bearings and double row tapered roller bearings
Tapping machine bearing have specially designed raceways and asymmetrical rollers. The bearings can accommodate axial loads acting in one direction and simultaneously acting radial loads. The load is transmitted between the raceways via the rollers at an angle to the bearing axis, while the flange guides the rollers.
Tapping machine bearing Application：
Tapered roller bearings are widely used in machine tool spindles, gear reducers, automotive drive axles, transmissions, rolling mills, mines, metallurgical industries, plastic machinery, household appliances, motors, pumps, machinery and other automotive parts.
Classification of tapered roller bearings
A single row tapered roller bearing has an outer ring, and its inner ring and a group of tapered rollers are an inner ring assembly enclosed by a basket cage. The outer ring can be separated from the inner ring assembly. According to the ISO taper roller bearing outline dimension standard, the outer ring or inner ring assembly of any standard model of taper roller bearing should be internationally interchangeable with the outer ring or inner ring assembly of the same model. That is, the outer ring of the same model must comply with the provisions of iso492 (gb307) in terms of external dimensions and tolerances, and the cone angle and cone diameter of inner ring components must also comply with the relevant provisions of interchangeability.
Generally, the taper angle of the outer race of single row tapered roller bearings is between 10 ° ~19 °, which can bear the combined action of axial load and radial load at the same time. The larger the cone angle, the greater the ability to bear axial load. For bearings with large cone angle, post code plus B, the cone angle is between 25 ° ~29 °, and it can bear large axial load. In addition, the clearance of single row tapered roller bearings can be adjusted during installation.
The outer ring (or inner ring) of double row tapered roller bearings is a whole. The small end faces of the two inner rings (or outer rings) are similar, and there is a spacer in the middle. The clearance is adjusted by the thickness of the spacer. The thickness of the spacer can also be used to adjust the pre interference of double row tapered roller bearings.
The performance of four row tapered roller bearing is basically the same as that of double row tapered roller bearing, but it bears more radial load than double row tapered roller bearing, and its limit speed is slightly lower. It is mainly used in heavy machinery.
Multi seal double and four row tapered roller bearings, ZWZ provides long-life, multi seal double and four row tapered roller bearings. Carry out personalized new design for bearings, change the traditional design method of fully sealed bearings, and adopt a new sealing structure combining sealing and dust prevention, so as to improve the sealing effect and sealing performance. Compared with open structure bearings, the service life of multi seal double and four row tapered roller bearings is increased by 20% – 40%; Lubricant consumption is reduced by 80%.
