Cylindrical Roller Bearings

Cylindrical Roller Bearings 

Cylindrical roller bearings are bearings that use cylinders as the rolling elements as opposed to balls in ball bearings. The rollers have a larger contact area with the outer ring and can issue loads across a wide surface. These bearings have two rings called an inner and outer ring that is separated by a set of cylinders. These cylinders support both rings, are supported with a cage, and reduce friction. Cylindrical roller bearings are used in electric motors, machine tool, steel mills, gearboxes, railways, and wind turbines. The following are some key considerations and benefits of cylindrical roller bearings:

  • Low friction
  • High load carrying capacity
  • High stiffness
  • Long service life
  • Increased operational reliability
  • Accommodate axial displacement
  • Accommodate faster speeds

The size and width of cylindrical roller bearings can vary according to their use and application. There are several types of these bearings. Single row are the most common and are separable which allows for easy mounting and dismounting. Double row and multi-row provide a larger radial load carrying capacity and can carry radial loads in one direction. Cylindrical rollers have a greater radial load capacity. The main design differences are the number of roller rows and inner/outer ring flanges and cage designs.
