Product Description
131.32.1400 is a three-row roller slewing bearing with external gear. It features three independent raceways: one for axial loads (upper), one for reverse axial loads (lower), and one for radial loads. Roller diameter is 32mm with 1400mm raceway center circle diameter. This design provides the highest load capacity among all slewing bearing types. This model is driven by a pinion meshing with the external teeth. It measures 1205mm inner diameter, 1595mm outer diameter, and 220mm height. With exceptional rigidity and load capacity, it is widely used in extra-heavy applications such as large cranes, ship loaders, and tunnel boring machines.
Key Features
Three-row roller design, Independent axial and radial raceways, Highest load capacity among slewing bearings, Maximum rigidity and stability, P0 precision standard (P5/P6 available), C3 internal clearance, Segmented brass or steel cage, External gear for powerful pinion drive
Applications
Large tower cranes, Ship loaders/unloaders, Stacker reclaimers, Bucket wheel excavators, Heavy-duty mobile cranes
