SEG 379 20 04 AA LM-SEG Series Slewing bearing

The SEG series is a single-row, four-point contact ball slewing bearing featuring an external gear on the outer ring. This series is part of Luoyang MC Bearing's specialized product range and is designed for applications that require compact dimensions, combined load capacity, and reliable performance in a variety of operating conditions.


Typical Applications:

Construction machinery such as cranes and excavators

Aerial work platforms and man lifts

Solar tracking systems

Radar and antenna positioning systems

Materials handling and conveying equipment



High load-carrying capacity
Resistance to high and low temperatures
Noise-free operation
Strictly controlled tolerances and appropriate internal clearance
Long service life and low maintenance requirements
Prevention of unexpected downtime (avoiding bearing fracture, seizure, and safety incidents caused by such failures, with anti-tilting capability)

Characteristics

✦ Four-point ball contact – Single-row balls contact the raceway at four points, handling axial, radial, and tilting moment loads in one compact unit.

✦ External gear on outer ring – Gear teeth cut directly on the outer ring for direct pinion engagement and rotary transmission.

✦ Segmented raceway design – Optimized ball-raceway contact geometry ensures smooth rotation and reduced friction torque.

✦ Induction-hardened raceways – Rolling surfaces hardened for wear resistance and extended fatigue life.

✦ Ready-to-mount – Both rings come with pre-drilled mounting holes for quick bolted installation.

✦ Heavy-duty construction – Manufactured from high-strength alloy steel, suitable for demanding applications like cranes and excavators.
