Four row tapered roller bearing

The performance of four row tapered roller bearings is basically the same as that of double row tapered roller bearings, but they have a greater ability to withstand radial loads and lower limit speeds compared to double row tapered roller bearings. They are mainly used in heavy machinery, such as steel mills, etc. These bearings are designed for extremely high radial and axial loads, as well as high-speed and impact loads, and are used in extremely adverse environmental conditions such as high temperatures, water, and pollution, New performance bearings can significantly reduce the overall life cycle cost of the rolling mill.

Features and advantages

Long service life

The four cup design (four independent outer rings) provides the best load distribution on all four rows of rollers.

Improve operational reliability

The optimized surface treatment of the contact surface between the roller and raceway is conducive to the formation of hydrodynamic lubrication oil film.

Improved wear resistance

The bearings are made of extremely clean and uniform steel, and undergo unique heat treatment to improve wear resistance.

Improved sealing performance, reduced leakage, and reduced frictional heat

The optimized sealing design can effectively prevent external pollution while maintaining low levels of friction and frictional heat. It can also better retain lubricants, minimize environmental impact, and reduce maintenance costs.
