FUD UltraLife® Our endurance runner!

For many years, we have had rolling bearings and linear technology manufactured worldwide according to our specifications. You will find the products on the market under the brand name FUD®and FUD UltraLife®.

FUD and FUD UltraLife rolling bearings & linear technology, we stand for tested quality at fair prices.

Our more than 75 years of experience in the field of drive technology flow into our products. FUD and FUD UltraLife have been successfully installed by well-known original equipment manufacturers (OEM) for many years. Our quality has proven itself in the market.

Learn about FUD®and FUD UltraLife®bearing production in the following slide show "THE BIG FIVE".

Below you will find our brochures on our products. Since our production programme is constantly being expanded, please also enquire about other series.

THE BIG FIVE of rolling bearing production

1. geometry

Bearings with the FUD UltraLife quality feature have narrowed dimensional running tolerances as standard. Features such as roughness, profile geometry and roundness are produced and controlled strictly according to FUD specifications.

In cylindrical roller bearings, for example, rolling elements and running surfaces are provided with a logarithmic profile to avoid stress peaks. This creates a modified line contact. The edge areas are relieved and the bearings are less sensitive to shaft deflection and misalignment.

2. rolling bearing materials

From the first second, the fatigue process begins in the bearing. Fine cracks begin to form below the surface of the contact surfaces of the rolling elements and raceways, which in the further course lead to larger breakouts.

These so-called pittings mean the certain failure of a rolling bearing. This type of damage depends on the purity of the steel used and the carbide distribution.

FUD has set itself the goal of increasing the service life of rolling bearings and offering customers added value.

The FUD MQS steel sets new standards in comparison - especially in the areas of purity and carbide distribution, the tolerances have been narrowed.

Compared to the DIN classification, this means that you can downsize and reduce your maintenance costs.

You benefit from the unique FUD UltraLife price-performance ratio. Bearings with the FUD UltraLife upgrade are produced from FUD MQS steel as standard.

3. process-accompanying control

The in-process control begins at the steelworks. Deliveries of raw material are analysed and documented according to FUD specifications.

Only materials approved by FUD are used. The dimensional accuracy is checked after each process.

Through our production code, we can offer you 100% transparency. Product-critical criteria such as hardness, main dimensions, purity of the raw material, etc. are summarised and archived in a test protocol.

Grinding burn test, hardness test, profile check is carried out regularly at coordinated intervals and guarantee you the FUD UltraLife quality standard.

4. service life tests

The high quality of our products is tested and proven on service life test stands under realistic conditions. Only bearings that have achieved very good results in the test are considered for the FUD UltraLife performance class. We will be happy to provide you with the test reports on request.

The tests are carried out by our cooperation partner ELGETI ENGINEERING. Here, the most modern testing equipment from predominantly our own development is available, which is also used for research in addition to quality assurance.

5. Last but not least

We are continuously working on the further development of our DIN ISO 9001:2015, thus ensuring the processes and thus the quality of our products. Click on the certificate to download it.

FUD super precision bearing

FUD/ZYS spindle bearings offer running accuracy that guarantees optimum production results. The uncompromising quality control during manufacture ensures that specified tolerances are reliably maintained when FUD/ZYS spindle bearings are used in machine tools.

The precise spindle bearings prevent vibrations on the tool spindle and thus also consequential costs, such as machine damage, production downtimes, expensive technician call-outs, etc.

FUD spindle bearings can be produced as hybrid bearings according to your requirements, e.g. with ceramic balls or peek cage in accuracy classesP2, PA4 / P4S, P5.

We manufacture spindle bearings in the following sizes:

71800 to 71834
71900 to 71956
7000 to 7048
7200 to 7244

with pressure angles of 15°and 25°(C or E)
Single or paired to sets of 2, 3and 4
in X, O or tandem arrangement
in light, medium or high preload
