Four-point contact ball style and surface contact roller style and four series: single-row spherical type, double-row spherical type, crossover rolling type and three-row rolling type.
We supplier four-point contact ball style and surface contact roller style and four series: single-row spherical type, double-row spherical type, crossover rolling type and three-row rolling type.
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.
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.

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
