Plain bearings

Plain bearings are components engineered to operate where stability, high wear resistance, and predictable performance are critical, even under severe conditions.

In this category, you will find plain bearings designed for industrial, maintenance, and structural applications, selected with the real-world needs of users in mind, rather than just catalog parameters.

Plain bearing – when simplicity and durability matter

A plain bearing does not contain any rolling elements. Movement occurs directly between the shaft and the bushing surface, which translates into quiet operation, high resistance to contamination, and the ability to operate under heavy loads. This represents an ideal solution where reliability, restricted mounting space, or elevated operating temperatures are critical factors.

Plain bearings are frequently chosen for continuously operating machinery, dusty environments, or applications where maintenance must be kept to an absolute minimum. Thanks to the appropriate selection of materials, it is also possible to deploy variants designed for dry operation or with minimal lubrication.

FAQ

What is the difference between a plain bearing and a rolling bearing?

A plain bearing does not utilize rolling elements—the shaft operates directly within the bushing. Consequently, it runs quieter, features a simpler design, and handles dusty or harsh operating environments more effectively.

When should I choose plain bearings over rolling bearings?

Plain bearings perform exceptionally well under heavy loads, in restricted mounting spaces, at high temperatures, and where resistance to contamination and reduced failure rates are paramount.

Can a plain bearing operate without lubrication?

Yes, a selection of plain bearings is fully adapted for dry running or operation with minimal lubrication, depending on the bushing material and operational conditions.

How to select the correct plain bearing for an application?

The applied load, operating speed, temperature, environmental conditions, and lubrication method must all be taken into account. In the Marat catalog, these parameters are detailed to ensure a quick and accurate selection process.

What are the most common applications for plain bearings?

Plain bearings are utilized in industrial machinery, production equipment, drivetrain arrangements, and structural configurations requiring stable and predictable performance.
