Bearing Types Slewing Ring Bearing
16278001 Slewing Ring Bearing Turntable Bearing for Large Excavators
The DT Series consists of the eight-point ball bearing Kaydon originally developed to provide maximum load capacity for given envelope and bolt circle diameters. It provides up to 80% increase in capacity over that of a single-row four-point design of the same diameter and bolt circles. Yet the DT Series has a smaller profile than a three-row roller design.
Design Features
The internal configuration consists of two deep groove gothic arch raceways, each with a maximum ball complement, located in both the inner and outer rings. This results in a total of eight surfaces where the balls may contact at any time, providing exceptional moment, thrust, and radial load capacities. Through precise manufacturing, the raceways are closely matched to provide a high degree of load sharing. Integral seals are provided to assist in the exclusion of contaminants.
Availability
DT Series bearings are made to order with a fully customizable hole pattern for bearing retention, and an internal or external gear or other drive mechanism.
Applications
DT Series bearings have been used successfully in heavy duty applications including:
❚ Large excavators ❚ Large cranes ❚ Mining equipment ❚ Wind turbines ❚ Telescopes
