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 TYPE NO TEETH

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.
