Kaydon Slewing Ring Bearings

In shovels, excavators, longwall miners, and other mining equipment, bearings are crucial to reliable performance. For repeatable precision with minimal downtime, specify rugged slewing ring bearings from Kaydon Bearings Division.

These precision bearings come in diameters from 2 inches to 240 inches (40mm to 6.1m), with radial capacities to 4,000,000 lbs. and thrust capacities to 18,000,000 lbs. Standard configurations include 4-point contact ball, 8-point contact ball, cross-roller, and 3-row roller bearings.

Most Kaydon slewing ring bearings can be provided with integral, induction-hardened gearing on the inner races or outer races. Paint and zinc thermal spray coatings are available for corrosion resistance, as well as Kaydon’s exclusive Endurakote® plating tp fight wear as well as corrosion.

In addition to its wide range of standard configurations, Kaydon is a leading developer of advanced custom bearings to meet customers’ specific application needs.


The TR series has three independent rows of rollers oriented to the load direction, resulting in the highest capacity for any given diameter. The top and bottom rows transmit moment loading, while the middle row transmits radial load. It is available in O.D.s up to 240” (6.1m).


XT Series bearings feature a rectangular cross-section with deep-groove gothic arch raceways and maximum ball complement. The resulting 4-point contact assures you of exceptional moment, thrust and radial load capacities. The XT is available with O.D. up to 240” (6.1m).
