Description

RKS.**2.*5.***4 ball bearing slewing ring for crane

RKS.**2.*5.***4 is single row 4 contact ball bearing, slewing bearing , the outer dia ***2mm, inner dia ***5mm,

height *8mm, that can accommodate axial, radial and moment loads acting either singly or in combination and in any direction.

They can perform both slewing (oscillating) movements as well as rotational movements.



Advantages:

1. High reduction ratio

Single-stage coaxial can obtain high reduction ratio of 1/*0～1/**0. The structure and structure are simple, but the device with high reduction ratio can be realized.

2. Small backlash

Unlike meshing with ordinary gears, the backlash is extremely small, this feature is an indispensable element for the controller field.

3. High precision

Multi-tooth meshes at the same time, and there are two ***-degree symmetrical gears meshing, so the effect of gear pitch error and cumulative pitch error on the rotation accuracy is more even, so that the position accuracy and rotation accuracy reach a very high level.

4. Fewer parts and easy installation

The three basic components achieve a high reduction ratio, and they are all coaxial, so the kit is easy to install and simple in shape.

5. Small size and light weight

Compared with the conventional gear device, the volume is 1/3 and the weight is 1/2, but the same torque capacity and speed reduction ratio can be obtained, and the size and weight are reduced.

6. High torque capacity

The flexible wheel material uses special steel with high fatigue strength. Unlike ordinary transmissions, the number of teeth that mesh simultaneously accounts for about *0% of the total number of teeth, and they are in surface contact, so that the pressure on each gear becomes smaller and a high torque capacity can be obtained.

7. High efficiency

The sliding position of the gear teeth is very small, which reduces the power loss caused by friction. Therefore, while achieving a high reduction ratio, high efficiency can be maintained and the drive motor can be miniaturized.

8. Low noise

The gear tooth meshing peripheral speed is low, and the transmission of power is balanced, so it runs quietly and has minimal vibration.
