They have a wide, flat bearing to provide stability in high-speed applications with high radial loads.

Cylindrical roller bearings can have single or double rows. They can be made of stainless steel, chrome steel, ceramic, or a hybrid form of construction. When selecting cylindrical?roller bearings, the dimensions of the bore and outer ring width, as well as operation specifics such as static radial load, dynamic radial load, and rated speed must be considered.
