Get to Know Inherent Features and Types of Cylindrical Bearings

Among several types of rolling bearings, cylindrical roller bearings are one of the famous types used to minimize friction between moving machine components. Their intrinsic features and types make them suitable for various applications in industrial sectors.

Much significance is given to cylindrical bearings for their designs, dimensions, sizes and series though they are more recognized for roller rows and the cage type. Based on the application, a cylindrical roller bearing, with one or two roller rows are used, as well as with or without a cage. Having a cage or not with a cage has several benefits:

  • Cylindrical roller bearings with a cage will be able to manage both radial and peak loads, as well as high speeds and quick accelerations.
  • Where an application asks for handling heavy radial loads at speed which is moderate, full complement cylindrical bearings, with no cage is used to help use more number of rollers.
  • The improvement in designs have combined both the heavy load-bearing capability and high speeds in bearings with a cage.

Know Some Innate Characteristics of Cylindrical Bearings

The prominence of cylindrical rolling bearings depends on their inherent features and some of the important ones are:

  • High Stiffness: The bearing is recognized for high moment stiffness.
    Excellent Load Carrying Capacity: The caged bearing with a sealed cap enables it to carry heavy loads at high speeds.
  • Manage Axial Displacement: You can use this type of bearing to handle axial displacement, except for the one that has flanges on outer and inner raceways.
  • Minimal Friction: The lubricant film formation owing to the roller-end design and open-flange design, as well as surface finish reduces friction and increases axial load carrying capability.
  • Extended Service Life: There is no or minimal edge stresses at the roller contact due to the logarithmic profile. This leads to minimal sensitivity to shaft deflection and misalignment.

What Are the Kinds of Cylindrical Bearings?

For successful application, cylindrical bearings are grouped based on their design. Some of the common ones are:

Single-Row Cylindrical Roller Bearings: They are known for some design variants, with respect to the material used, configuration of outer and inner raceway flanges and cage design. The integral flanges are present either on the inner or outer ring. They may be two on the outer or inner rings and nothing on the other, or two on the outer rings and one on the inner ring. This helps manage axial displacement in both directions or one direction.

Single-Row Full Complement Cylindrical Roller Bearings: They are typically used to accommodate heavy radial loads, while offering higher radial stiffness.

Double-Row Full Complement Cylindrical Roller Bearings: They come with the second row of rolling elements to helps manage heavy radial loads, with increased stiffness.

The above information makes cylindrical bearings more suitable for several applications.
