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.

Availability
XT series bearings are made to order, and can be customized for the specific application.

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
