Three Row Roller Bearing
1.Description
In case of the same size, our TR series three row roller bearing is able to provide higherloading capacity than our other
2. Features
a. This line of roller bearing isdesigned with three-row independent rollers and the normal direction of theserollers is the same with the load direction. This configuration can maximizethe loading capacity, reduce friction resistance, and minimize flexuraldeformation.
b. The top and bottom rows of rollers can not only bear bidirectional thrustloads but also share the torque loads exposed to the middle row of rollers.
c. The arrangement of rollers and spacers as well as the matched raceway iswell-designed to make the three row rollerbearing meet the requirements on load or other aspects.
d. To exploit the abovementioned advantages, the stiffness and flatness of thesupporting structure should be higher than those for the XT or DT series slew ringbearing.
e. Gear teeth or other transmission mechanism can be arranged on the supportingstructure of the inner or outer ring as per customer requirements. Also, theform of the bearing hole can be specified by the customers.
3. Supply Capacity
The three row roller bearing is producedin strict accordance with the orders so as to meet customer needs.
4. Application
The three row roller bearing isapplicable to heavy-load occasions requiring extremely high stiffness andperformance, including
a. Radar
b. Crane
c. Excavator
d. Stacker
e. Reclaimer
f. Heavy duty rolling mill
