Design Features

The internal configuration consists of deep groove gothic arch raceways and maximum ball complement. This results in a four-point contact design that 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 nongeared configurations.

  • Cranes
  • Aerial lifts
  • Excavators
