Three-row roller bearings can bear various loads at the same time. They have the largest load-bearing capacity among the four products. They have larger shaft and radial dimensions and a solid structure. They are especially suitable for heavy machinery requiring larger diameters.
Application
It is especially suitable for heavy machinery requiring larger diameter, such as
bucket wheel stacker and declaimer,
wheel crane,
marine crane,
port crane,
ladle turret,
large tonnage truck crane,
heavy machinery and so on
Features
1. Compared with the cross-roller bearing, under the same bearing diameter, the number of rolling elements (contact points) is increased, thereby reducing the load on each rolling element; After the contact is changed to line contact, the contact stress can be reduced and the bearing capacity can be improved.
2. Since the radial force and the axial force are borne by the two rows of rollers respectively, the direction of the reaction force is consistent with the main direction of the load on the bearing, so the contact load between the rollers and the raceway can be reduced.
3. Under the same load, it has smaller dimensions, smaller section and lighter weight than other types of supports, which can save materials and reduce material costs.
4. The raceway of the rolling ring is a plane and a cylindrical surface, which is more convenient to process.
5. In addition to bearing radial force, the vertical roller also has the guiding function of bearing the tilting moment.
