Kaydon MT Slewing Ring Bearings

MT Series slewing ring bearings have a rectangular cross-section and come in sizes ranging from 4 to 47 inches in outer diameter (100 to 1200 mm). The internal configuration includes deep groove gothic arch raceways and maximum ball complement, creating a four-point contact design that ensures exceptional moment, thrust, and radial load capacities. Integral face riding seals are used for the larger sizes, while non-contact shields are used for the smaller sizes, aiding in the exclusion of contaminants. These features make MT series heavy-duty slewing rings suitable for a broad range of applications, from light to heavy duty.

MT series slewing ring bearings are available in nongeared (MTO) and externally geared (MTE) configurations. The gears are either Fellows Stub Involute for sizes up to MTE-324 or Stub Involute for larger sizes, all manufactured to AGMA Class Q6 quality. MT series slewing bearings have ball pitch diameters ranging from 9 to 40 inches and can handle moment load ratings of up to 870,000 ft.-lbs.

Applications

MT series slewing ring bearings have demonstrated successful performance in a diverse range of applications, spanning from light to heavy duty. The smaller sizes are particularly suitable for applications like:

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

The features of Kaydon’s MT slewing ring bearings are as follows:

1. Rectangular Cross-Section: MT series slewing ring bearings are likely to have a rectangular cross-section, providing additional load-carrying capacity and stiffness.
2. Size Range: The MT series is expected to come in a wide range of sizes, covering diameters from 4 to 47 inches (100 to 1200 mm).
3. Deep Groove Gothic Arch Raceways: The internal configuration of MT series bearings may include deep groove gothic arch raceways, enhancing their load-carrying capabilities.
4. Four-Point Contact Design: The MT series slewing ring bearings are likely to feature a four-point contact design, allowing them to handle moment, thrust, and radial loads effectively.
5. Integral Face Riding Seals: For larger sizes, MT bearings may have integral face riding seals to protect against contaminants and maintain bearing integrity.
6. Non-Contact Shields: Smaller sizes of MT series bearings may come with non-contact shields for additional protection against contamination.
7. Geared and Non-Geared Configurations: The MT series may be offered in both nongeared and externally geared configurations to suit different applications.
8. Gear Design: If the MT bearings are available in geared versions, the gears are likely to be manufactured with Fellows Stub Involute (for certain sizes) or Stub Involute (for larger sizes) designs, meeting AGMA Class Q6 quality standards.
9. Moment Load Ratings: MT series slewing ring bearings are likely to have moment load ratings ranging up to 870,000 ft.-lbs, making them suitable for various heavy-duty applications..
