Products Description
K3780-3720 Taper roller bearing consists of four components: the cone, or inner ring; the cup, or outer ring; the tapered rollers, or rolling elements; and the cage, or roller retainer.
K3780-3720 Single-row tapered roller bearing is able to carry radial and axial load in one directions simtaneously because an axial component of produced when this type of bearings loaded radically, two bearings are used together facing one another, or two or more bearings are matched and used.
Special tapered roller bearings for various applications: wheels, differential, transmission, etc.
Products Description
Single Row Tapered Roller Bearings
Single row tapered roller bearings have an outer ring, an inner ring and a set of tapered rollers enclosed by a basket-shaped cage into an inner ring assembly. The outer ring can be separated from the inner ring assembly. According to the ISO tapered roller bearing external dimension standard, any standard type of tapered roller bearing outer ring or inner ring assembly should be able to achieve international compatibility with the same type of outer ring or inner ring assembly. exchange. That is to say, the outer dimensions and tolerances of the same type of outer ring must comply with the provisions of ISO492 (GB307), and the cone angle of the inner ring components, the diameter of the cone of the components, etc. must also comply with the relevant regulations for interchangeability.
Usually, the taper angle of the outer ring raceway of a single row tapered roller bearing is between 10° and 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 withstand axial loads. For bearings with a large cone angle, add B to the post code, and the cone angle is between 25° and 29°, which can withstand large axial loads. In addition, single row tapered roller bearings can adjust the size of the clearance during installation.
Double Row Tapered Roller Bearings
The outer ring (or inner ring) of double row tapered roller bearing 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, and the pre-interference of the double row tapered roller bearing can also be adjusted by the thickness of the spacer.
Four row tapered roller bearings
Four-row tapered roller bearings, the performance of this kind of bearing is basically the same as that of double-row tapered roller bearings, but it bears a larger radial load than double-row tapered roller bearings, and the limit speed is slightly lower. It is mainly used in heavy machinery.
Multi-sealed double and four-row tapered roller bearings
Multi-sealed double and four-row tapered roller bearings, ZWZ provides long-life, multi-sealed double and four-row tapered roller bearings. Carry out a new personalized design for the bearing, change the traditional design method of the fully sealed bearing, and adopt a new type of sealing structure combining sealing and dustproof to improve the sealing effect and performance. Compared with open structure bearings, multi-sealed double and four-row tapered roller bearings have a 20% to 40% increase in life and 80% reduction in lubricant consumption.
