OEM Palletizing robot Use Single Row Crossed Roller Slewing Bearing 111.25.630

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 play a vital role in the development of industrial robots and are widely referred to as "machine joints".

Single row Crossed roller slewing bearing to withstand the overturning moment, axial force and radial force of industrial robots, including dynamic and static working conditions, the transmission reducer only bears the rotating torque of the rotary shaft, so cross-rollers are required under such conditions. The slewing bearing has high precision and ensures the rotation accuracy of the robot.

XZWD slewing bearing has supplied many products for Industrial Robots. Such as Palletizing robot use Single row Crossed roller slewing bearing 111.25.630, 110.28.1000 etc.

Note:

1. N1 is the numbers of lubricating holes. Oil cup M10×1JB/T7940.1~JB/T7940.

2.The Oil nipple's location can be change according to the user's application.

3. n-φ can change to tapped hole, the diameter of tapped hole is M, and depth is 2M.

4. The tangential tooth force in the form is the max tooth force; the nominal tangential tooth force is 1/2 of the max one.

5. "K" is addendum reduction coefficient.
