What are cylindrical roller bearings?

Cylindrical roller bearings, as the name suggests, are types of bearings that feature cylinders as the rolling element. The cylindrical rollers facilitate a greater linear contact area along the outer ring, which allows equal distribution of loads across a larger surface. As a result, cylindrical roller bearings are capable of carrying comparatively higher radial loads as well as supporting higher speeds. Cylindrical roller bearings with double rows possess greater radial rigidity, which makes them most suitable for precision machine tools. 

Types

Cylindrical roller bearings come in a multitude of variants, ranging in size and design. The variants usually differ based on several parameters, including the number of roller rows and inner and outer ring flanges, material composition, and cage design. 

Based on cage design, cylindrical roller bearings are available primarily in two types: 

• Sealed bearings
• Split bearings

Based on the number of roller rows, cylindrical roller bearings are commonly available in the following types:

• Single row cylindrical roller bearings
• Double row cylindrical roller bearings
• Four row cylindrical roller bearings
• Single row full complement cylindrical roller bearings
• Double row full complement cylindrical roller bearings

Benefits of cylindrical roller bearings

The benefits provided by cylindrical roller bearings are:

• These types of roller bearings are capable of supporting heavy radial loads.
• They can accommodate high speeds.
• They can rectify axial displacement.
• Roller bearings cylindrical rollers offer high stiffness and low friction.
• They are well equipped to deliver a long service life.
