Four Row Cylindrical Roller Bearings
Multi-row or 4 row cylindrical roller bearings are mainly made and used as roll-neck bearings in rolling mills. The four rows of rollers offers itself to bring huge radial loads for the given bearing cross-section. American Roller's four row cylindrical roller bearings are designed with contoured rollers with limited diametrical tolerances to optimize the capacity of this birthing to evenly distribute the tons to all 4 rows. The most usual types include making use of a machined brass finger cage or a machined light steel finger cage. No suffix is needed for the brass cage but the SM suffix is made use of for the steel. In larger sizes, the use of a steel pin-type cage with hollow rollers is standard. Many external race as well as inner race setups and design kinds are readily available to meet installation or interchangeability requirements. Most 4 row cylindrical roller bearings are provided with C4 Interior Radial Clearance and P5 Precision to carry out well in these roll-neck applications.
Our patented Blended Bevel leading side on our Inner Races is common. This one-of-a-kind layout permits smoother installation of the Chock/Outer Race Roller Setting Up over the Roll installed Inner Race O.D. when robotic stand structure devices is made use of. It can also aid when larger chocks utilizing bearings of this style are installed making use of above cranes. In applications requiring concentric grinding of the placed inner race and also roll body, an "RG" suffix is designated to define a race with extra stock for grinding. These bearings are also offered with a conical bore internal race for applications needing greater precision or control of mounted radial clearance. The suffix "K" assigns a 1:12 or K30 marks 1:30 taper if required. Four Row, multi-row bearings are generally made use of in the key metals industry to roll ferrous and non-ferrous products. Utilized mainly on rolls in two high rod and also bar mills, and backup roll rolls on 4 high mills, these bearings are sector compatible and also are usually offered as Outer Race Roller Assemblies and also Inner Race Sets.
