multi-rowMulti-row or four row round roller bearings are largely designed and utilized as roll-neck bearings in rolling mills. The 4 rows of rollers offers itself to carry large radial loads for the offered split needle bearing cross-section. American Roller's four row cylindrical roller bearings are developed with contoured rollers with tight diametrical tolerances to make the most of the capability of this birthing to equally distribute the lots to all four rows. One of the most typical kinds consist of the use of a machined brass finger cage or a machined mild steel finger cage. No suffix is required for the brass cage however the SM suffix is utilized for the steel. In larger dimensions, the use of a steel pin-type cage with hollow rollers is typical. Several outer race and internal race setups and also layout kinds are readily available to meet setup or interchangeability demands. Most four row round roller bearings are supplied with C4 Inner Radial Clearance as well as P5 Accuracy to perform well in these roll-neck applications.

Our copyrighted Blended Bevel leading edge on our Inner Races is standard. This one-of-a-kind style permits smoother installment of the Chock/Outer Race Roller Assembly over the Roll installed Inner Race O.D. when robotic stand structure tools is utilized. It can likewise assist when larger chocks using bearings of this design are mounted using overhead cranes. In applications calling for concentric grinding of the mounted internal race and roll body, an "RG" suffix is marked to specify a race with added stock for grinding. These bearings are likewise available with a tapered bore inner race for applications calling for greater accuracy or control of placed radial clearance. The suffix "K" marks a 1:12 or K30 marks 1:30 taper if needed. Four Row, multi-row bearings are commonly made use of in the main metals industry to roll ferrous and also non-ferrous materials. Utilized mostly on rolls in two high pole as well as bar mills, and backup roll rolls on four high mills, these bearings are sector interchangeable and are commonly offered as Outer Race Roller Assemblies and Inner Race Sets.
