Four-row cylindrical roller bearings are essential components for steel rolling mills, as they must withstand heavy loads and operate reliably under harsh conditions. This unique design (four rows of rollers) ensures high load-carrying capacity and improved rigidity, making it an ideal choice for steel rolling mills.

Among the bearing models, bearing 313822 (280mm*390mm*220mm) is widely used in the steel mills.

One of the key benefits of the 313822 bearing for steel rolling mills is its ability to handle high speeds. Rolling mills operate at high speeds, and bearing 313822 is designed to handle high speeds without sacrificing performance or reliability. The lubrication system of the bearing will ensure proper lubrication of the rollers and raceways, even at high speeds.

Bearing 313822 is also featured with heavy carrying loads. Steel rolling mills require bearings that can handle heavy loads, while the four-row design of the bearing distributes the load evenly across all four rows of rollers, ensuring that the bearing can handle heavy loads without premature wear or failure.

In addition, four-row cylindrical roller bearing 313822 is highly durable and requires minimal maintenance. It is made from high-grade steel that has been heat-treated to improve its strength and durability. The rollers are precision-ground to ensure uniform contact with the raceways, reducing friction and wear. The bearing is also equipped with a sealing system that protects against contamination and moisture, further extending its lifespan.
