Four Row Cylindrical Roller Bearings

If you're in the market for a new four-row cylindrical roller bearing, there are a number of options available to you. NSK, SKF, and American Roller all offer different four-row designs. Choosing the right bearing for your needs depends on the type of load you'll be putting it through.

SKF four-row cylindrical roller bearings

SKF four-row cylindrical roller bearing designs are available in a variety of sizes and configurations. These bearings differ primarily in the number of roller rows, inner and outer ring flanges, cage design, and material used. These types of bearings provide high stiffness and long service life.

These bearings are designed to withstand high speeds and radial loads. Their low cross-sectional height allows them to accommodate large roll neck diameters. These properties also help reduce the friction in the bearing, thereby improving its performance.

American Roller's four-row cylindrical roller bearings

Four-row cylindrical roller bearings are highly versatile in their design. They are available in both cylindrical and tapered bore designs. These bearings are available with different press-in distances and lubrication holes. Many of them are also equipped with a supplementary code called "W". The machined bronze retainer helps to maintain the proper distance between the rolling elements and helps minimize vibration and noise. As a result, these bearings are quiet to operate.

Four-row cylindrical roller bearings are used mainly in heavy machinery. They are widely used for roller presses and calenders. Their radial load capacity is also very high. The high load carrying capacity makes them a desirable choice for high-speed rolling applications.

SKF's X-life four-row cylindrical roller bearings

SKF has expanded its Explorer series with the four-row cylindrical roller bearing (X-CRB). Designed for demanding applications in long-product rolling mills, the 4rCRB solves the common problems associated with cylindrical roller bearings: high loads, varying speeds, reversing torques, and contamination. The improved robustness against these issues results in increased reliability.

A rolling element bearing is a type of bearing with cylindrical rollers that rotate within a raceway. Their simple geometry allows for a close tolerance in manufacturing and provides good radial load-carrying capacity. However, they are sensitive to misalignment, and therefore are subject to rapid wear.
