TGB double row ball slewing bearing internal gear replacement

Introduction
Slewing rings are mechanical elements designed to withstand high loads (axial, radial and tilting moment) while performing rotational movements to displace the load. The axial loads are the ones applied on the same direction as the rotation axis, while the radial loads are perpendicular to this axis.

The main parts of the slewing ring are two rotating rings and the rolling elements between them. Both rings are provided with holes for bolts that can be threaded or through holes to ffx the part to the structure. All the slewing rings without teeth can be also ordered with inner teeth or outer teeth. The slewing ring load capability depends on its size and geometry and also on the type and amount of the rolling elements. For each slewing ring there is a load diagram that shows the maximum load that the slewing ring can withstand in terms of axial load and tilting moment.
