Features and advantages of QIBR four-row cylindrical roller bearing FCDP series

QIBR four-row cylindrical roller bearing FCDP series solves multiple key problems in various fields, which are mainly reflected in the following aspects:

1. High load capacity

Four-row cylindrical roller bearings can provide high radial load carrying capacity, especially suitable for applications that need to bear large loads. The structure of four-row roller bearings enables it to accommodate more rollers, thereby increasing its load capacity.

2. Compact structure

Due to the four-row roller arrangement, its structure is relatively compact and can bear large loads in a limited space. Therefore, it is often used in space-constrained occasions, especially in some large mechanical equipment.

3. Adapt to high load and heavy load conditions

QIBR four-row cylindrical roller bearing FCDP series can effectively distribute pressure so that each row of rollers can bear a certain load. They are very suitable for high-load occasions that require large axial and radial loads.

4. Good durability

Due to the large contact area between the rollers and the raceway, it can effectively share the load, so its service life is relatively long, suitable for long-term high-load working occasions.

The performance improvement and solutions of QIBR four-row cylindrical roller bearing FCDP series 

1. Sealing material selection

Using high-performance sealing materials, such as high-temperature and chemical-resistant rubber or polyurethane materials, can ensure that the bearings work normally in extreme environments.

2. Optimizing rollers

QIBR four-row cylindrical roller bearing FCDP series can reduce contact stress, improve load capacity and durability by optimizing roller shape. Roller surface treatment can reduce friction, improve rolling accuracy and load capacity, and extend the service life of bearings.

3. Improving manufacturing accuracy

QIBR four-row cylindrical roller bearing FCDP series adopts advanced foreign processing equipment and processes, such as precision grinding, super-finishing grinding, etc., to improve the geometric accuracy of inner and outer rings and rollers, reduce processing errors, and thus improve the rotation accuracy and roughness of bearings.

4. Improve material performance

QIBR four-row cylindrical roller bearing FCDP series uses surface coating technology (such as chrome plating, nitriding, etc.) to improve the wear resistance and corrosion resistance of the bearing, effectively extend the service life of the bearing, especially when working in harsh environments, the performance of the bearing can be significantly improved.
