Certificate: BV, CCS, ISO9001Accommodate axial displacement
Except for bearings with flanges on both the inner and outer rings.
Low friction (Roller end / flange contact area)
The open flange design , together with the roller end design and surface finish, promote lubricant film formation resulting in lower friction and higher axial load carrying capacity.
Long service life
The logarithmic roller profile reduces edge stresses at the roller/raceway contact and sensitivity to misalignment and shaft deflection.
Enhanced operational reliability
The surface finish on the contact surfaces of the rollers and raceways supports the formation of a hydrodynamic lubricant film.
Separable and interchangeable
The separable components of SKF cylindrical roller bearings are interchangeable . This facilitates mounting and dismounting, as well as maintenance inspections.

Features of slewing bearing:
1.High precision:Cross roller bearings can be made high precision bearings, at P4, P2.
2.High rigidity:These series roller bearings are with preload.
3.High load capacity:This series roller bearing can support axial load, radial load, and tilting load.
4.Small volume:This series roller bearing can save space for the machine.
Applications of slewing bearing:
slewing ring bearing solutions have been used successfully in a variety of light to medium duty applications including:
Small cranes, booms, and lifts
Industrial positioners and rotary tables
Chute swivelsStretch wrapping machinesBottle filling machinesConveyors and related material handling equipmentRotating displaysTadano Crane Slewing Bearing refered to slewing bearing used in Tadano Crane.
A slewing bearing or slew[ing] ring is a rotational rolling-element 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. (To "slew" means to turn without change of place.)
Compared to other rolling-element bearings, slewing bearings are thin in section and are often made in diameters of a metre or more; the slewing bearings on the Falkirk Wheel are 4 metres diameter and fit over a 3.5 metre axle. Slewing bearings resemble oversize aircraft control surface bearings.
Slewing bearings often use two rows of rolling elements. They often use three race elements, such as an inner ring and two outer ring "halves" that clamp together axially. | Brand Name | Large Diameter 010.20.250 Tadano Crane Slewing Bearing |

Slewing bearing
Double row different diameter ball slewing bearing has three seats. The steel balls and the spacers may be directly arranged into the upper and lower raceways.
Two rows of steel balls with different diameters are fitted according to the load. Such open mode fitting features extraordinary convenience.
The load angles of both upper and lower races are 90°, which enable the bearing to bear large axial force and the overturning moment. When the radial force is larger than 1/10 of the axial force, the raceways should be especially designed.
The axial dimension and radial dimension of doublerow ball slewing bearing are rather large, and the bearing construction is sturdy.
Hence it is especially suitable for tower cranes which requiring working diameter over medium range, mobile cranes and other unloading machines.
