THE DESCIPTION OF THE PRODUCT Structure: Cylindrical Type: Roller Brand Name: CWN Bore Size: 15 - 90 mm Outside Diameter: 35 - 160 mm Place of Origin: Jiangsu China (Mainland) The rollers in a single row cylindrical roller bearing are always guided between the integral "open" flanges on one of the rings. These "open" flanges combined with the specially designed and surface treated roller ends, provide improved lubrication, reduced friction and consequently lower operating temperature. The ring with the integral flanges together with the cylindrical roller and cage assembly can be separated from the other ring. This results in easy mounting and dismounting, particularly where the load conditions are such that interference fits are required for both rings.
