Cylindrical Roller Bearings
Cylindrical roller bearings come in many variations. They can differ from the number of roller rows, type of cage, and the configuration of the inner and outer ring flanges.
These cylindrical or spherical roller bearings are used in many industries and are used to carry radial loads that are heavy in mass.
Having a set of these roller bearings can help to improve a company’s productivity and reduce cost as well. With improved efficiency and versatility, your company can gain the edge in its production quality and proficiency.

They can be differentiated by the number of rollers they have, the design of their cages, and the position and number of guide flanges. Below, we’ll explain the slight differences between the single, double, and four-rowed rollers.
Number of Rollers
The one row option can carry heavy radial loads. They have a wide variety of configurations and multiple cage designs. You can get them in ISO metric and inch formats.
Single rows rollers are designated as NU, NJ, NUP, N, and NF. They are also commonly used in general industries, electrical motors, and gearboxes.
For the double-rowed cylindrical ball bearings, they are able to handle heavier radial loads as compared to single rows. Plus, axial loading of up to Fa ≤ 0, 25 Fr. This design is typically metric dimensioned with a machined brass cage which enables for smooth rolling on the brass finger cage.
Double rows rollers are either NNU or NU, depending on the presence of a side rib cage.
Cylindrical roller bearings with four rows are designed to have a cylindrical or tapered bore, or are open or sealed. Four-rowed variation can only work in handling radial loads. Thus, they are normally installed together with deep groove ball bearings, angular contact ball bearings, or tapered roller bearings. This would therefore enable both axial and radial loading.
The designation for four rows cylindrical roller bearings is NNUP.
Benefits Of Cylindrical Roller Bearings
High Precision and Accuracy
Cylindrical roller bearings are characterised by its moderate thrust-, and high radial-load abilities. As a result, they are able to cater to production that requires high precision and accuracy.
Faster Production at Lower Cost
Because of its high strength cage design in pressed steel, and machined brass, it produces only minimal noise and heat generated. Therefore, requiring lesser energy in temperature control as well as lesser friction that causes wear-and-tear.
It is low-maintenance and can last longer than most applications.
