Three-row Cylindrical Roller Combined Slewing Bearing

130

The three-row roller slewing bearing has three rings, and the upper, lower and radial raceways are separated so that the load of each row of rollers can be accurately determined.

131

Externally toothed three-row roller slewing bearing, especially suitable for heavy machinery requiring larger diameters.

132

The externally toothed three-row roller slewing bearing is ideal for heavy machinery requiring larger diameters, ensuring robust performance and precise operational control.

133

Internally toothed three-row roller slewing bearing is suitable for bucket wheel excavators, wheeled cranes, marine cranes, port cranes, molten steel running tables, large-tonnage truck cranes and other machinery.

134

The internally toothed three-row roller slewing bearing is ideal for heavy machinery such as bucket wheel excavators, wheeled cranes, marine cranes, port cranes, molten steel running tables, and large-tonnage truck cranes.

DTR TYPE NO TEETH

DTR type slewing bearings have a triple-row compound cylindrical roller bearing structure, with either the outer or inner ring split into two in the axial direction, composed of a total of three raceways and three rows of cylindrical rollers.

DTR-T TYPE EXTERNAL TEETH

DTR-T slewing bearings are equipped with various features such as high shock resistance, high load rating, and high sealing performance required for supporting the main cutter of a tunnel boring machine.

DTR-T TYPE INTERNAL TEETH

DTR-T slewing bearings have the same triple-row compound cylindrical roller bearing structure as DTR bearings, and are equipped with various features.

RD 900

Three-row roller bearing slewing rings Axial-roller bearings are availablewithout gear with external gear with internal gear.

ROD_DA

The increase in load-bearing capacity is directed towards the height of the bearing, and various loads are borne by different raceways and roller groups.

ROD_DJ

A large bearing with a special structure that integrates multiple functions such as support, rotation, transmission, and fixation.

SP-DTR-T EXTERNAL TEETH

When DTR-T slewing bearings used with forced circulation lubrication, the bearing is provided with an oil inlet and an oil drain port.

TR

Three-Row Roller,Three independent rows of rollers, oriented for optimal performance,Greatest stiffness and capacity for a given diameter,Internal, external, or non-gear.
