What Are Cylindrical Roller Bearings?

There are many different types of bearings that each offer their own advantages. The right part is vitally important for your design, which is why bearing suppliers like Ritbearing provide a wide range of bearing styles to accommodate your needs, such as cylindrical roller bearings.

Cylindrical Roller Bearing Basics

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.

What are Cylindrical Roller Bearings Used For?

With their combination of greater radial load capacity, ability to accommodate faster speeds, and other benefits, cylindrical roller bearings are ideal for use in a variety of industries. Typical markets that can utilize these parts include:

What are Common Causes of Cylindrical Roller Bearings Failures?

Like all other types of bearings, cylindrical rollers require care and maintenance. Flaking or pitting, cracking and chipping, scratches, and rust are among the most common causes of cylindrical roller bearing failure.

Fortunately, you can limit the risk of bearing failure. There are preventative measures you can take to reduce the risk of bearing damage. Check out our posts on what you can do to help prevent or detect the following potential problems:
