Journal bearings are ideal for meeting future requirements in terms of power density, service life and cost optimization. They are already proven in a wide range of applications. As one of the world's leading manufacturers, we design and manufacture flexible solutions to meet your specific needs. Benefit from the performance-enhancing alternative to other bearing systems.
We would be pleased to inform you about our journal bearings .
Get in touch with us!
All our journal bearings are based on hydrodynamic or hydrostatic technology. They float on a film of oil or lubricant, thanks to an active oil supply provided by an existing infrastructure or independently. This has many advantages:
We also use metallic bearings with a layered structure, flexible design and the latest coating technologies. This ensures that we can meet your specific requirements. We offer 2 basic types of journal bearings:
Our journal bearings with an innovative material structure are available as half shells or bushings. They consist of several layers of different materials. This multi-layer design enables higher loads to be accommodated. We can flexibly adjust the properties of the materials to maximise the performance and life of your bearings.
Our journal bearings can be optimised for extremely high speed and dynamic applications. This flexible and customised design ensures exceptional performance and stability in the most demanding applications. The special design also ensures quiet operation and high load carrying capacity. Another special feature is the maximum possible bearing size of up to 3 ½ m in diameter.
If your bearings are not performing as they should, this could be due to the wrong type of bearing.
Are your current bearings unable to cope with the high loads and speeds? Miba journal bearings are designed to meet these requirements and offer a robust solution. They keep your machines running longer.
Is your installation space limited and do you need compact solutions? Journal bearings from Miba require less space and help to increase power density. So you can get more out of your available space.
Want to make your design lighter without sacrificing strength? With Miba journal bearings, you can reduce the weight of your applications without compromising performance.
You already have plain bearings in use, but these are
Our multi-layer, partially lead-free radial bearings are highly resilient and environmentally friendly.
For applications requiring velocities between 5 m/s and 180 m/s, Miba's journal bearings are the perfect solution. By combining the most suitable materials with flexible design, we can cover a wide range.
To ensure optimum results, we simulate the conditions prior to implementation. We also validate the relevant parameters on our in-house test bench before delivery.
We at Miba have a high level of materials expertise. Materials are produced in our own plants. This gives us the unique opportunity to have full control over the composition of materials and to tailor them to specific requirements.
Our development team can quickly test, find and adjust the ideal composition of materials. In this way, we produce materials that can withstand extreme loads of up to 180 MPa.
Journal bearings from Miba are characterised by their hydrodynamic operation, in which the bearing moves on a fluid film. This makes them virtually maintenance-free, especially in 24/7 operation.
While other bearing systems have a service life of around 5,000 operating hours, hydrodynamic plain bearings offer a unlimited service life in hydrodynamic mode. Maintenance is also easier because plain bearings are lighter and are sometimes designed in segments or half-shells. This means that usually only parts of the bearing need to be serviced and replaced.
Off-the-shelf bearing systems may seem very attractive in terms of price. However, they often cannot keep up with requirements that demand more flexibility. The longer service life and lower maintenance requirements of Miba journal bearings result in considerable savings over the entire service life of the system.
Contact us and arrange an initial consultation.
At Miba, we are able to develop and manufacture flexible solutions quickly and efficiently. Thanks to our extensive know-how and access to a wide range of technologies and materials, we always take care to avoid complexity and oversizing. Our aim is to provide you with the perfect technical solution.
No matter how demanding your requirements, give us your toughest challenge and we will find a solution. Let us work together to implement the optimum plain bearing solution for your system.

Miba journal bearings are the ideal choice for demanding applications. This is made possible by our advanced technologies and extensive know-how.
We are located close to our customers' production sites in the USA, South America, Asia and Europe.
With our own primary material plant and continuous support from development to spare parts service, we offer all-round service for our customers.
Our various storage solutions meet your specific requirements efficiently. We achieve this without driving up costs.
A radial bearing supports radial loads by allowing a shaft to rotate while reducing friction. It uses either a lubricating film or rolling elements such as balls and rollers. This ensures smooth and efficient motion and minimises wear.
No, Miba does not offer clinched bushings. We use rolled bushings made of solid material, which guarantees higher quality and performance.
A low-maintenance hydrodynamic plain bearing uses a film of oil or lubricant. The shaft then 'floats' on this oil film. This significantly reduces wear as there is virtually no direct contact between the bearing surfaces. It also dampens vibration, is quiet and is particularly suitable for applications with constant loads.
In contrast, self-lubricating bearings have built-in lubricants that often require regular maintenance and re-lubrication.
