MTE-145 Slewing Ring Bearing  Structure 12.286*5.709*1.968inch
 

Product Description

The  MTE Series represents a line of heavy-duty, externally geared slewing ring bearings engineered to deliver an optimal balance of economy and load capacity within a compact envelope dimension. Part of the broader MT Series, these bearings are a popular choice for original equipment manufacturers (OEMs) and end-users seeking reliable rotation solutions for medium to heavy-duty applications 

Designed as a direct and economical replacement for kingpost-style pivot designs, the MTE series utilizes a sophisticated four-point contact geometry. This design allows a single bearing to efficiently manage combined axial, radial, and moment loading, simplifying associated support structures 

Design & Construction

The MTE series is characterized by a rectangular cross-section available in a range of sizes, typically from 4 inches to 47 inches in outside diameter (approximately 100 mm to 1200 mm)

Internal Geometry:
At the core of the MTE bearing is its deep groove "Gothic arch" raceway design. This configuration, combined with a maximum ball complement, creates a four-point contact bearing. In this design, the balls contact the raceways at four distinct points, which provides exceptional stability and high load capacities-specifically moment, thrust, and radial loads-in a single bearing unit 

 

Sealing & Protection:
To ensure longevity in harsh environments, the MTE series incorporates integral sealing:

• Larger Sizes: Fitted with integral face-riding seals to actively exclude contaminants like dirt and debris.

• Smaller Sizes: Equipped with non-contact shields to protect against larger particles while minimizing rotational torque

Key Specifications

• Pitch Diameters: Ball pitch diameters range from 9 inches to 40 inches, accommodating a wide variety of rotational requirements 

• Load Ratings: These bearings are built to handle substantial forces, with moment load ratings available up to 870,000 ft.-lbs. 

• Mounting: Mounting holes are provided in both inner and outer rings. Sizes with a "T" suffix (e.g., MTE-415T) indicate the presence of threaded mounting holes with a minimum thread depth of 1.5 times the nominal hole diameter, simplifying installation and eliminating the need for nuts on the backside 

• High-Capacity Variants: Certain part numbers ending in an "X" suffix are designed to offer additional load capacity beyond the standard configuration for that envelope size 

Applications

Thanks to their robust design and versatility, Kaydon MTE series bearings are successfully utilized across a broad spectrum of industries. Their ability to handle combined loads makes them ideal for equipment requiring smooth, heavy-duty rotation 

Typical applications include:

Light to Medium-Duty:

• Manipulators

• Jib cranes

• Lift-assist devices

• Work positioners

Heavy-Duty:

• Truck-mounted cranes

• Aerial lifts (e.g., cherry pickers, boom lifts)

• Hoists

• Small wind turbines

• Non-precision industrial tables and positioners
