four-row cylindrical roller Bearing inner ring outer assembly

Four-row cylindrical roller Bearing inner ring outer assembly are primarily designed and used as roll-neck bearings in rolling mills. The four rows of rollers lends itself to carry large radial loads for the given bearing cross section. Contoured rollers with tight diametrical tolerances maximize the ability of this bearing to evenly distribute the load to all four rows. 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 bearings are supplied with C4 Internal Radial Clearance and P5 Accuracy to perform well in these roll neck applications.


These use rollers as the rolling elements and have a high load capacity. The rollers are guided by the ribs of the inner or outer ring. The inner and outer rings can be separated to facilitate assembly, and both can be fitted tightly.On types with no ribs, either the inner or the outer ring can move freely in the axial direction, making cylindrical roller bearings ideal for use in free side bearings that absorb shaft expansion.
