The rolling mill is the important equipment that implements the metal rolling process. It has the characteristics of large load, high speed, harsh working environment, frequent roll changes, and high precision requirements. Both bearing and bearing chock are the key parts served to the rolling mill machine.
Bearing chock
The rolling mill bearing chock is one of the important components of the rolling equipment. The rolling mill chock is the direct bearer of the roll load. The rolling force is transmitted to the rolling mill bearing seat through the bearing. Therefore, whether the rolling mill bearing seat has a reasonable structure and whether the accuracy meets the requirements It has an important impact on the service life of bearings and the safe operation of rolling mills. Rolling mill bearing seats bear heavy loads, have complex structures, high precision requirements, long manufacturing cycles, and are prone to deformation during processing. CYM can provide you with high-quality bearing seats and technical support.
Rolling mill bearing
Changyear can provide you with the following commonly rolling mill bearings and introduce their types and characteristics to you.
- Radial bearing
It can withstand large impact loads and is generally used in the following types of radial bearings for rolling mills.
① Double-row radial spherical roller bearings It has the characteristics of self-aligning and can withstand medium load and rolling force. It is mostly used as the backup roll of small and medium-sized rolling mills.
② Four-row cylindrical bearing: It is easy to obtain high machining accuracy, so it has high-speed rotation characteristics, and because it is easy to install and disassemble, the inner ring raceway surface and the roll surface can be ground simultaneously after the inner ring is pressed into the roll neck. , which is beneficial to improving rolling accuracy and is mostly used in the back-up rollers of high-speed and high-precision rolling mills. This type of bearing can withstand high radial force but cannot withstand axial force, so a separate thrust bearing must be added.
③ Four-row tapered roller bearing: They can bear both radial load and axial load, but they need to be assembled strictly according to the serial number during assembly. They are mostly used for backup rolls and work rolls of large rolling mills.
- Axial thrust bearing
It is mainly used to bear the axial force and prevent the axial movement and misalignment of the roll. There are mainly the following types of thrust bearings used for rolls:
① Double row tapered roller bearing: can withstand bidirectional axial loads and are suitable for high-speed and large-load rolling mills.
② Deep groove ball bearing: can withstand radial and bidirectional axial loads, and are suitable for high-speed and low-load rolling mills.
③ Four-point contact ball bearing: can withstand radial and bidirectional axial loads, and are suitable for high-speed and low-load rolling mills.
