Cylindrical Roller Bearing

Single row cylindrical roller bearing

Description：

The single row cylindrical roller bearing is a type of rolling-element bearing that consists of cylindrical rollers held in place by a cage (or retainer) between inner and outer races. These bearings are designed to provide support for radial loads, meaning they primarily carry loads perpendicular to the axis of rotation. Single row cylindrical roller bearings are versatile components widely used in engineering applications where radial load support and high-speed capabilities are required.
