Cylindrical Roller Bearings
The main difference between cylindrical roller bearings and other bearing styles is in the name – they use cylinders as the rolling elements as opposed to the balls you’d find in ball bearings. The cylinders are slightly greater in length than diameter. Compared to ball bearings, cylindrical rollers have a greater radial load capacity. The cylindrical roller design also allows these parts to accept relatively faster speeds than other styles of roller bearings.
There are multiple types of cylindrical roller bearings. Single row cylindrical rollers are the most popular and are separable, which makes for easier mounting and dismounting. However, these may not be able to support the radial load of certain applications. Double row and multi-row cylindrical roller bearings offer greater radial load capacity and can also transmit axial loads in one direction.
Like other styles, cylindrical roller bearings have various clearance and lubrication options available depending on the manufacturer and supplier. Cylindrical roller bearings can be made with a cage or as a full complement part.
