XT Series slewing ring bearings are custom designs having a rectangular cross section, and are available in sizes up to 218 inches OD (5500 mm). They are well suited for a wide range of applications where our standard product series do not meet your size, capacity, or weight requirements.

Design Features

The internal configuration consists of deep groove gothic arch raceways and maximum ball complement. This results in a four-point contact design which provides exceptional moment, thrust, and radial load capacities. Integral seals are provided to assist in the exclusion of contaminants.

XT Series bearings are available in internal geared, external geared, and non geared configurations.

Applications

XT Series bearings have been used successfully in a wide range of applications, including:

❚ Cranes❚ Aerial lifts❚ Excavators❚ Wind turbines❚ Utility derricks❚ Log loaders and feller bunchers❚ Grapples❚ Mining equipment
