Three-row Roller Slewing Ring for Heavy-duty Cranes

Three-row roller slewing ring

Three-row roller slewing ring has three separate rings and three rows of rollers. The rows have distinct functions: one row handles axial loads, while the other two (upper and lower) handle radial loads and tilting moments.

Features & performance advantages

Super heavy load, high friction, large footprint, durability.

Its line contact and separated load paths allow it to withstand massive shock loads and complex combined forces. Its high friction leads to low-speed, high-torque rotation. So it's typically used for low-speed, high-torque applications.
