FAQS

QWhat is Rotek Slewing Ring ?

ARotek slewing bearings are machine elements which absorb all axial and radial forces and the resulting tilting moments in a single self-retaining and ready-to-install unit.Their low profile and an excellent weight/performance ratio, open center, and the possibility of an integrated gearing make Rotek slewing bearings ideal structural components.

QWhat is slewing bearing ?

AA slewing bearing or slew[ing] ring is a rotational rolling-element bearing that typically supports a heavy but slow-turning or slow-oscillating load, often a horizontal platform such as a conventional crane, a swing yarder, or the wind-facing platform of a horizontal-axis windmill

QWhat is Crawler Crane Slewing Bearing?

AA Crawler Crane Slewing Bearing or plain bearing that typically supports a heavy but slow-turning or slow-oscillating load, often a horizontal platform such as a conventional crane, a swing yarder, or the wind-facing platform of a horizontal-axis windmill. Compared to other rolling-element bearings, slewing ring bearings are thin in section and are often made in diameters of a meter or more. Slewing bearings are often made with gear teeth integral with the inner or outer race, used to drive the platform relative to the base. As a professional slewing rings supplier, we provide small and large swing bearing with high performance.

QWhat is Double Row Angular Contact Ball Slewing Ring ?

ADouble Row Angular Contact Ball Bearings. Double Row Angular Contact ball bearings have two rows of balls arranged back-to-back. The lines of action of the load at the contact between balls and raceways (load lines) diverge at the bearing axis and form an angle of 30° to the radial plane.
