A slewing motor provides rotational motion for slewing mechanisms in machinery such as cranes, excavators, and turntables. It rotates the superstructure or boom around a vertical axis.
The rated torque range is 500–5000 N·m, and the rated speed is 0.5–5 r/min. These are reference values; confirm the exact specifications for your application with the manufacturer.
The operating pressure is 1.0–1.6 MPa, with a maximum of 2.5 MPa. The listed standards serve as references for pressure testing, but compliance must be verified with the supplier.
Selection is based on load, gear ratio, required torque and speed, and environmental conditions. Use the reference parameters as a starting point, but always consult the manufacturer for model-specific data and verification.
