The type and selection of rolling mill bearings

Common types of rolling mill bearings include:

1. Four-row cylindrical roller bearing: This kind of bearing can bear radial force and is widely used in supporting parts of backup rolls and rolls.

2. Thrust roller bearing: This kind of bearing can withstand axial force, and is usually used in rolling mills with large rolling force but low speed.

3. Spherical roller bearing: This kind of bearing can bear radial and axial forces at the same time, and is often used in rolling mills with large rolling force and high speed.

4. Tapered roller bearing: This kind of bearing can bear radial and axial forces, and is usually used for supporting parts of support rolls and rolls.

When selecting rolling mill bearings, the following factors need to be considered:

1. Bearing load: Different types of rolling mill bearings can bear different loads. It is necessary to choose a suitable bearing according to the load and working requirements of the rolling mill.

2. Working speed: Different rolling mill bearings have different working speed ranges, and it is necessary to choose a suitable bearing according to the working speed requirements of the rolling mill.

3. Working environment: The working environment of rolling mill bearings is usually relatively harsh. It is necessary to consider the influence of lubricating fluid, iron filings and other sundries, and select suitable bearing materials and sealing forms.

4. Bearing size: Different rolling mills need to use bearings of different sizes, and it is necessary to choose a suitable bearing according to the design size requirements of the rolling mill.

To sum up, choosing a suitable rolling mill bearing needs to consider many factors, and it is necessary to choose a suitable bearing type and model according to specific work requirements and equipment design.
