[Slewing ring bearing] What is the difference between slewing ring and rolling bearing

1. As far as everything is normal, the slewing ring contains the abs gear ring for the rolling drive and its anti-fouling sealing equipment. This equipment has a key effect on ensuring that all the slewing rings are normal and low-speed gears run for a long time.

2. The standard of roller bearing is generally small, while the standard of slewing bearing is very large, its diameter is generally 0.4-10 meters, and some slewing bearings have a diameter of about 40 meters. Perhaps this kind of sufficient necessary conditions is not widespread.

3. In terms of operating speed, compared with roller bearings, the operating speed of slewing bearings is lower, generally below 50 revolutions per minute. In many places where it is necessary to roll the rolling bearing, the slewing bearing does not continue to run, but only reverses the rolling within the angle of view, which is tantamount to "shaking the rolling bearing".

4. The installation method of slewing ring and general roller bearing is different. The slewing bearing is not sleeved on the spindle and installed in the rolling bearing box like ordinary rolling bearings, but it is fixed on the upper and lower rubber bearings with screws.

5. Slewing bearings generally need to bear loads of multiple levels, not only radial and axial forces, but also large collapse torque. Therefore, a complete set of slewing bearings generally has the same effect as ordinary roller bearings.

6. There is a big difference between a slewing ring and a roller bearing in terms of production and processing technology such as raw materials and quenching and tempering.

The left and right refers to the 6 differences between the slewing bearing and the general roller bearing. Mastering the difference of this kind of rolling bearing is for the company to have a proactive effect in production, production and use. According to the need, select the rolling bearing produced by the appropriate company to promote Rolling bearings can give full play to greater industrial production results.
