The DT series utilizes eight point ball bearings to provide maximum load capacity for a given envelope and bolt circle diameter. DT Series slewing rings provide up to 80% higher load carrying capacity than single-row four-point designs of the same diameter and number of bolt turns. However, the DT series has a smaller profile than the three-row drum design.
Design Features
The internal configuration consists of two deep grooved gothic arched raceways, each with a maximum ball allowance, located on the inner and outer rings. This results in a total of eight surfaces that the ball can contact at any time, providing excellent moment, thrust and radial load capacity. Manufactured with precision, the raceways are closely matched to provide a high degree of load distribution. Integral seals are provided to help keep contaminants out.
Availability
DT series bearings are custom made with fully customizable bore patterns for bearing fixation, and internal or external gears or other drive mechanisms.
Application
DT series bearings have been successfully used in heavy duty applications including:
