Use of Ball Bearing Rollers for Better Performance and Long Service Life

The role of bearings is unpredictable in the rotational movements of some machines, especially a motor or an actuator. They help two metal surfaces to move easily with less torque by rolling instead of sliding and at high or moderate rotational speed. It is however important to choose an appropriate bearing for an application to ensure high performance and long service life.

When selecting bearings for a machine, it is also essential to be certain to attain the necessary level of machine performance at the lowest cost possible. That being the case, it is also important to look at the robustness for the conditions in which the machine is operated and maintained may vary and may be difficult to know. There are also other things to consider when deciding on the size, dimension and series of the bearing for an application. Here are a few important factors to consider:

• Shaft fits
• Mounting procedure and maintenance
• Lubricant used and the method of supply
• Bearing clearance class
• Cage material
• Bearing sealing
• Dimensional solidity
• Precision requirements

By not considering any or some of the above, if you select a wrong bearing, it may result in the quick wear and tear, as well as premature failure of the equipment. There are several types of bearings to help you with a right choice.

Get to know Different Types of Ball Bearing Rollers

Rolling bearings are grouped into two: Radial and Thrust for easy understanding. Irrespective of their design and classification, bearings consist of the mechanical elements such as an outer ring, inner ring, rolling elements and a cage. These components are made of steel, except for the rollers which may sometimes come in ceramic. The rollers are designed in different shapes such as cylindrical, conical spherical, and tapered.

Cylindrical roller bearings: With the rollers in cylindrical shapes, which are guided by ring ribs, these bearings can accommodate axial and radial loads. They are commonly used in automotive industry, along with the other automobile bearing like the tapered roller thrust bearing.

Spherical roller bearings: With symmetrical rollers in two rows, these bearings have spherical outer raceways and inner rings, which are inclined at an angle to the axis of the bearing. You can find the spherical roller bearings in different types like the spherical tapered bore bearing and spherical roller thrust bearing. They are used to support heavy radial and axial loads in either direction.

Tapered roller bearings: They are known for the tapered rollers and raceways, both inner and outer designed to bisect at the point on the centerline.

There are still more to go when looking at the classifications of ball bearing rollers. Nevertheless, they are meant to handle heavy loads while performing various critical machine operations.
