Special Drive Solutions (SDS)
Single-Row Ball Slewing Bearings
Single-row ball slewing bearings (SR-B, 4-point contact). Versions with internal, external or no gear teeth. Universal solution for mobile and portal cranes, excavators, rotating platforms, medical and power-generation equipment.
Double-Row Ball Slewing Bearings
Double-row ball slewing bearings (DR-B). Two rows of equal-diameter balls on upper and lower raceways increase axial load capacity and tilting moment. Used on tower and crawler cranes, medium-duty excavators, rotating platforms.
Double-Row Non-Equal Diameter Ball Slewing Bearings
Double-row non-equal diameter ball slewing bearings (DR-NE). Upper larger-ball row carries the main axial and tilting loads, lower row handles reversal and radial forces. Solution for heavy-duty mobile cranes, crawler excavators, port and drilling equipment.
L-Type Slewing Bearings
L-type slewing bearings with one L-shaped ring. Compact, gear-free design that handles axial and tilting loads efficiently. Used on manipulators, rotary tables, medical and industrial equipment.
Three-Row Roller Slewing Bearings
Three-row roller slewing bearings (TR-R). Three separate rows of rollers independently carry bidirectional axial and radial loads — the highest capacity and tilting moment in the family. Used on 150–1000 t port and crawler cranes, wind turbines, bucket-wheel excavators and drilling rigs.
Cross Roller Slewing Bearings
Cross roller slewing bearings (CR-R). Rollers alternate at 90° — a single compact row simultaneously carries axial, radial and tilting loads with high running accuracy. Used in industrial robotics, medical CT scanners, CNC rotary tables and precision optical equipment.
