MTE-540T Slewing Ring Bearing Turntable Bearing for Cranes

MT Series slewing ring bearings have a rectangular cross-section and range in size from 4 – 47 inches OD (100 – 1200 mm). They provide optimal economy and capacity for a given envelope dimension.

Design Features

The internal configuration consists of deep groove gothic arch raceways and maximum ball complement. This results in a four-point contact design which 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 them an ideal choice for a 

wide range of applications from light to heavy duty.

MT Series bearings are offered in non-geared (MTO) and externally geared (MTE) configurations. The gears are Fellows Stub Involute up to the MTE-324 size and Stub Involute for larger sizes, all manufactured to AGMA Class Q6 quality. Contact Kaydon for tooth backlash allowance.

Part numbers ending in a “T” suffix have threaded mounting holes. Thread depths are a minimum of 1.5 times the nominal hole size diameter indicated.Part numbers ending in an "X" suffix provide additional load capacity.


MT Series bearings have been used successfully in a wide range of applications from light to heavy duty.

The smaller sizes are well suited for:

❚ Manipulators❚ Jib cranes❚ Lift-assist devices❚ Work positioners

Larger sizes are well suited for:

❚ Truck-mounted cranes❚ Aerial lifts❚ Hoists❚ Small wind turbines❚ Non-precision positioning tables
