SLEWING BEARINGS WITH TRIPLE ROLLER BEARING ROWS, INNER GEAR TEETH

DESCRIZIONE
ISB slewing bearings in the ZR3 standard series are comprised of three rows of crossed roller bearings, two of which accommodate axial loads and the other radial loads, separated by a spacer in Nylon, with inner gear teeth. The triple row construction is comprised of three forged rings, one of which with inner gear teeth and two which form the untoothed outer ring, bound together with screws. The load applied to this type of bearing is distributed across the three rows of rollers in the same way and in the directions in which it is applied, without angular decomposition. This allows the triple roller row structure to withstand very heavy loads with high tilting moments.

VANTAGGI
