Things you want to know about Cylindrical Roller Bearings


Cylindrical Roller Bearings are designed to handle radial load at high performance and speed. Because of their particular design, These Bearings are one of the most suitable options for carrying multiple radial loads yet there are some other factors too that define the ultimate outcome or performance of this apparatus. In order to get the maximum results from these, you must optimize their cost, weight, performance, load capacity and durability. As these bearings are used for long term, you have to select the suitable variation according to your need carefully.

Design

These cylindrical roller bearings have two rings called inner and outer ring that are separated by a set of cylinders that not only support both rings, but also reduce the overall frictional force. These cylinders are supported by a rib or cage attached with either inner or outer ring depending on the variation you are using. On the other hand, the number of cylinders or rollers used in a Cylindrical Roller Bearing may vary and effect of increasing this number is increment in overall performance because of the obvious reasons.

Applications

As you have anticipated the effectiveness and efficiency of these Bearings, you probably have guessed that Cylindrical Roller Bearings are essential part of any machinery that comes with rotating parts. These are widely used in papermaking industry, electric motors, railways, motorcycles, pumps, wind turbines and gearboxes. Although these Bearings are used in above mentioned industries but their use is not limited there because of their high performance and durability even under stressful conditions.

Material and Structure

These Bearings are made with several different kind of material based on their applications and use, although alloy steel is a widely used material in these because of it offers maximum durability to rollers, rings and even the roller cage. In order or achieve more performance with high acceleration and speed as well as more carrying capacity while sacrificing durability, these Bearings are made with pressed steel too. In some cases, polyamide cages are used.

Variations and Models

Mainly there are three variations of these Bearings; single row Cylindrical Roller Bearings, double row Cylindrical Roller Bearings and multi row Cylindrical Roller Bearings. The names of these models are self explanatory.

Single row Bearings

These come with a single set of inner and outer ring as well as a single set of cage and rollers. There are several subtypes of single row Bearings and the difference between them is placement of cage and rollers.

Double row Bearings

These are similar to single row Bearings except they come with two set of inner and outer rings as well as two sets of rollers and cage. This model is used in precision machines because of their augmented strength, increased accuracy and enhanced carrying capacity.

Multi row Bearings

These offer high carrying capacity with lower performance.
