ZZ slewing bearings are designed for slow-speed, heavy-load rotational movements in construction machinery, wind power equipment, port cranes, mining machines, aerial work platforms and other industrial equipment. They support axial, radial and tilting-moment loads while providing smooth rotation and long service life.
Heavy-Duty Slewing Bearing
Available structures include single-row four-point contact ball, double-row ball, cross-roller, three-row roller and ball-roller combined slewing bearings. ZZ also provides custom designs based on load conditions, mounting dimensions, rotation speed, precision and operating environment.
Typical applications include excavators, cranes, solar trackers, wind turbines, port handling equipment, robotics and medical devices. With controlled heat treatment, machining and quality inspection, ZZ slewing bearings are suitable for demanding industrial use.
For selection, please provide load type, tilting moment, rotation speed, installation space, bolt circle dimensions and required precision. ZZ engineers can recommend a standard model or develop a customized slewing bearing solution.
