Kaydon DT Slewing Ring Bearings

The internal structure comprises two deep groove gothic arch raceways, each with a maximum ball complement, positioned in both the inner and outer rings. This arrangement creates eight contact surfaces for the balls, ensuring outstanding moment, thrust, and radial load capacities. The raceways are carefully matched through precise manufacturing to enable a high degree of load sharing. Additionally, integral seals are included to prevent the entry of contaminants.

Applications

DT series bearings have been used successfully in heavy-duty applications including:

• Large excavators
• Large cranes
• Mining equipment
• Wind turbines
• Telescopes

The key features of Kaydon DT series slewing ring bearings include:

1. Eight-Point Ball Bearings: The DT series utilizes eight-point ball bearings developed by Kaydon to maximize load capacity within given envelope and bolt circle diameters.
2. Exceptional Load Capacity: The bearing’s internal configuration, with two deep groove gothic arch raceways and maximum ball complement in both inner and outer rings, provides outstanding moment, thrust, and radial load capacities.
3. Precise Load Sharing: Through precise manufacturing, the raceways are closely matched, ensuring a high degree of load sharing and even distribution of loads.
4. Increased Capacity: Compared to single-row four-point designs of the same size, the DT series offers up to an 80% increase in load capacity.
5. Compact Design: Despite its increased capacity, the DT series maintains a smaller profile when compared to three-row roller designs.
6. Integral Seals: The bearings come with integral seals to protect against contaminants, enhancing performance and extending the bearing’s service life.
7. Versatility: The DT series is suitable for various applications where high load capacity and compact design are essential.
8. Customization: Kaydon offers custom design options to meet specific size, capacity, and weight requirements for unique applications.
