A slewing bearing or slew[ing] ring (also called a turntable bearing) is a rotational rolling-element bearing that typically supports a heavy but slow-turning or slowly-oscillating loads in combination (axial, radial and moment loads), often a horizontal platform such as a conventional crane, a swing yarder, or the wind-facing platform of a horizontal-axis (yaw) windmill. In other orientations (e.g. a horizontal axis of rotation) they are used in materials handling grapples, forklift attachments, welding turnover jigs and so on.

Outer ring diameter range: 200mm-4000mm Oem available Material: 42crmo / 50mn Rolling-element: ball, roller

FRUN industry slewing rings bearing can take moment load and radial load, besides take thrust loads. There are ball bearings, roller bearings and ball-roller bearings at type. At type of structure, there are single-row, double-rows and three-rows. It with teeth and without teeth on conduction outer-ring or inner-ring) at dust-proof and leak grease proof type, with air-proof and without air-proof. At mount , it with flanged (outer-ring or inner-ring), with bolt hole and without flanged. Industrial packaging.

Specifications: Raceway diameters: Standard models from 12" to 120" Capacities: Thrust: from 80,000 to 2,700,000 pounds Moment: from 16,000 to 6,700,000 pounds Radial: from 16,000 to 800,000 pounds Gearing: Internally geared, externally geared or gearless models are available. Applications: Excavators, Lift truck rotators, Industrial turntables, Capstans, Turnstiles, Mining equipment and Antennas. DPB Crossed Roller Slewing rings are built with V-groove raceways providing two roller paths in each ring. By alternating adjacent rollers at right angles to one another, one-half of the rollers transmit loads in one direction with the other half transmitting loads in the other direction. The crossed roller bearing design provides a higher theoretical dynamic capacity per unit size, greater stiffness, and a lower spring rate than a single roll ball slewing ring design

Double row cBearingsylindrical are distinguished by great rigidity and are prevailingly used for spindel arrangements of machine-tols and similar equipment. For accommodating high radial forces, it is suitable to use special multi row cylindrical roller bearings, especially in applications with limited space.
