Steel ball bearings are a type of rolling bearings that have three main functions while facilitating movement: carrying load, reducing friction and positioning moving machine parts.

Ball bearings use ball bearings to separate two “rings” or bearing rings to reduce surface contact and friction on the moving plane.

What are ball bearings made of?

Most ball bearings are made of a type of steel known as high carbon chromium steel, often called chrome steel. This is used for reasons of cost and durability. Bearings are also made from other materials such as stainless steel, ceramics and plastic.



Angular Contact Bearings

designed to work under combined radial and axial loads.


Axial Bearings

also called thrust ball bearings, these are designed to work under force applied parallel to the bearing’s axis, or thrust loads.


Deep-Groove Bearings

designed to carry both radial and light axial loads.


High-Speed Angular Contact Bearings

Self-aligning Ball Bearings

bearings with two sets of balls that are self-aligning and to carry both radial and light axial loads.


Linear Bearings

designed to allow movement in one direction along a linear axis.

What is the difference between a STEEL roller bearing and a STEEL ball bearing?

Roller  vs. Ball Bearings

A steel ball bearing is a spherical unit that accomplishes the same objective as a roller bearing. The real difference has to do with the contact surface between the bearing and the rail. For ball bearings (assuming a perfectly spherical bearing and no deformation), the contact surface is just a single point.

Bearings and bearing related products are very important components in most machinery. Their main purpose is to roll by reducing friction.
Various applications require that bearings be specifically designed to handle specific types of loads. For example, most radial ball bearings can withstand both radial and thrust loads. 

Roller bearings are more suitable for places where only radial load is required. Before selecting and installing a specific type of bearing, the intended use of the bearing as well as the rated load should be considered to limit the speed.

What Is the Purpose of steel ball Bearings?

The main purpose of bearings is to prevent direct metal-to-metal contact between two elements that are in relative motion. This prevents friction, heat generation and ultimately, the wear and tear of parts. It also reduces energy consumption as sliding motion is replaced with low-friction rolling.

They also transmit the load of the rotating element to the housing. This load may be radial, axial, or a combination of both. A bearing also restricts the freedom of movement of moving parts to predefined directions as discussed above.
