What is a Roller Bearing?

A Roller Bearings is a type of Bearing made up of cylinders called rollers. These parts withstand greater radial loads than needle or ball elements. They reduce friction, thanks to their large contact surface.

The durability of machines is increased when they are equipped with this type of component. They are also suitable for a wide range of applications and withstand the toughest conditions (resistance to impact, high speeds and high temperatures).

The different types of roller Bearings

Several types of components are available on the market.

Cylindrical roller Bearings

Cylindrical Roller Bearings tolerate high speeds and heavy radial loads. It also handles axial displacement. These mechanical parts are extremely robust and offer low friction. They are available with or without split seals.

Spherical Roller Bearings

Spherical Roller Bearings is a component designed for a wide range of applications, such as wind turbine shafts or applications where components are subjected to high levels of vibration. These parts can be open or sealed.

Tapered Roller Bearings

Taper Roller Bearings tolerate high loads. They are ideal for harsh or contaminated environments. These components are highly resistant to high temperatures and vibrations. They consist of a cup, itself composed of a cage-roller assembly and an outer ring, and a cone.

Other types of Roller Bearings

There are many other types of roller components:

Toroidal roller Bearings, Spherical Roller Thrust Bearings, Combined Roller, Single-row Spherical Roller Thrust Bearings, Tapered, Roller Thrust Bearings with shoulder.

The Rubix Selection

We offer a wide range of products of all types and brands. Discover our Schaeffler Group INA and FAG Bearings, as well as SKF and NSK Bearings.

What are their applications?

Roller Bearings can be found in many mechanical systems with high radial loads. These include rolling mill rolls, pressure rollers, electric motors and axleboxes.

How to choose a Roller Bearing?

To make the right choice, we recommend the following criteria:

Measure your parts precisely (bore, thickness, etc.).

Material: generally stainless steel (inox).

Bore shape.

Internal clearance.

Presence or absence of integrated seals.

Model technical data.

What are the advantages of Roller Bearings?

Roller components are rigid and strong. They can support heavy loads and adapt to different speeds and temperatures. As a result, they are particularly well suited to harsh environments.
