The rings of single row cylindrical roller bearings are flanged on one of the rings that guide the rollers during operation. These are sometimes called the “open” flanges. The rollers’ end surfaces are particularly treated to have better lubrication, lower friction, and lower operating temperature, when they roll by the “open” flanges. Its’ separable design of rings the roller and cage assemblies facilitating a better and easier mounting and dismounting job.
