FAG Barrel Roller Bearings ‌is a special cylindrical roller bearing with a drum-shaped roller, which is usually used to bear large radial loads and compensate for centering errors. This bearing consists of a solid outer ring with a spherical raceway, a solid inner ring with two ribs and a cylindrical or tapered hole, and a drum roller with a cage. ‌

Structural features

The structural features of FAG drum roller bearings include: ‌Inseparable‌: This bearing is inseparable and suitable for applications that require high strength and high stability. ‌Self-aligning‌: It has a self-aligning function and can compensate for a certain angle deviation. It is suitable for occasions with large centering errors. ‌Applicable temperature range‌: The operating temperature can reach 150 degrees. For bearings with an outer diameter of more than 120mm, the operating temperature can reach 200 degrees and still maintain dimensional stability. ‌

Application scenarios

FAG drum roller bearings are particularly suitable for the following scenarios: ‌Large radial load‌: Suitable for mechanical equipment that needs to withstand large radial loads. ‌Alignment error compensation‌: Under impact radial load, its structural strength is very superior and can compensate for alignment errors‌

Maintenance and care

In order to ensure the long-term stable operation of FAG drum roller bearings, the following points should be noted:

‌Lubrication‌: Check and replace the lubricating oil regularly to ensure that the bearings are well lubricated.

‌Cleaning‌: Before installation, the bearings should be thoroughly cleaned to ensure that there are no impurities and oil residues‌.

As a cornerstone of Schaeffler Group’s heavy-duty bearing portfolio, FAG Barrel Roller Bearings (also known as spherical roller bearings) redefine reliability in applications demanding exceptional shock absorption, shaft misalignment compensation, and heavy radial/axial load capacity. Engineered with patented logarithmic roller profiles and advanced materials, these bearings excel where conventional designs fail – from vibrating screens in mining to paper mill dryer sections.
