Three Row Roller Slewing Bearing
It have three seat rings, the upper and lower raceways and the radial raceways are separated, so that the load of each row of roller can be determined accurately. Being able to bear all kinds of loads at the same time, it is the largest one of the four structural products with large axle and radial dimensions and firm structure. It is especially suitable for heavy machinery requiring larger diameter, such as bucket wheel stacker and reclaimer, wheel crane, marine crane, port crane, ladle turret and large tonnage truck crane. Heavy machinery and so on.
The slewing bearing can rotate independently in three directions; the slewing bearing has simple, compact and reasonable structure; and the slewing bearing has high cost performance, is convenient to maintain, and satisfies the requirements of accuracy, bearing and multi-function of the device
Three-row roller slewing bearing is equipped with seat-rings, upper or bit. Neither orbit and radial orbit is seperated individually, it makes the load of each row of the rollers can be confirmed, making it can undertake all kinds of different load simultaneously. Three row roller slewing bearing’s carring capacity is the biggest among four models and the axial and radial size arre rather large to some extent, the structure of the three row roller slewing bearing ring is very firm.
