Kaydon's MT series heavy duty slewing ring bearings

Kaydon's MT series heavy duty slewing ring bearings offer a wide variety of solutions for applications such as truck mounted cranes, hoists, and non-precision industrial tables and positioners, providing optimal economy and capacity for a given envelope dimension.

MT Series kaydong slewing ring bearings have a rectangular cross-section and range in size from 4–47 inches OD (100–1200 mm). 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 face riding seals for the larger sizes, and non-contact shields for the smaller, assist in the exclusion of contaminants. These features make MT series heavy duty slewing rings an ideal choice for a wide range of applications from light to heavy duty.
