Four row bearings

Multi-row or four row cylindrical roller bearings are primarily designed and used as roll-neck bearings in rolling maills. The four rows of rollers lends itself to carry large radial loads for the given bearing cross-section. American Roller's four row cylindrical roller bearings are designed with contoured rollers with tight diametrical tolerances to maximize the ability of this bearing to evenly distribute the load to all four rows. The most common types include the use of a machined brass finger cage or a machined mild steel finger cage. No suffix is required for the brass cage but the SM suffix is used for the steel. In larger sizes, the use of a steel pin-type cage with hollow rollers is standard. Many outer race and inner race configurations and design types are available to meet installation or interchangeability requirements. Most four row cylindrical roller bearings are supplied with C4 Internal Radial Clearance and P5 Accuracy to perform well in these roll-neck applications.
