Swing bearing for Koehring LCD-150

The swing bearing, part number 7094609, serves as the primary mechanical interface between the crane chassis and the rotating superstructure. By allowing the upper assembly, which houses the operator cab, engine, and counterweight, to rotate relative to the carrier, this component enables the precise positioning required for lifting operations. It is engineered to support the full vertical load of the superstructure as well as the overturning moments generated during heavy-duty lifting tasks.

This component is designed for use in the Koehring LCD-150 and is compatible with the Lorain LCD 150 and Terex LCD-150 crane models. The bearing assembly consists of hardened steel rings and internal rolling elements that manage friction while distributing weight across the mounting surface. Proper installation and regular lubrication are necessary to maintain the structural integrity of the connection between the upper and lower crane sections during operation.

In heavy machinery, a swing bearing acts as the central pivot point for the entire upper structure. It must accommodate both axial and radial forces simultaneously, ensuring that the rotation remains smooth and stable even when the crane is operating under load or at maximum reach. This bearing type is essential for the operational range of motion in mobile cranes.
