Rolling bearings for pumps and compressors

Pumps and compressors are indispensable in many sectors of the process industry. Therefore, they must have high durability and repeatability to minimize downtime. These are associated with high costs and productivity losses. For this reason, the longest possible operating time between failures is of paramount importance. Pump and compressor manufacturers are striving to develop more compact machines to enable downsizing of bearings. This allows them to achieve greater efficiency and productivity.

Our rolling bearings for pumps are suitable for a wide range of pumped media, such as seawater, cooling water, refrigerants, paints and varnishes, bitumen, chocolate, foodstuffs and lubricating oils and greases. Our bearings with cages made of sheet steel, brass or polyamide are particularly popular. We also offer cylindrical roller bearings, deep groove ball bearings, single and double row angular contact ball bearings, tapered roller bearings, spherical roller bearings and four point contact bearings.

With NSK bearings, you are always on the safe side. We have the best solutions for seawater pumps, cooling water pumps, centrifugal pumps, metering pumps, feed pumps, radial piston pumps, rotary piston pumps, industrial heat pumps, eccentric screw pumps and gear pumps.

Rolling bearings for pumps and compressors

Welcome to your reliable authorized NSK dealer!

As a partner of the world's leading manufacturers of pumps and compressors, we know how important it is to reduce your costs and increase productivity at the same time.

Pumps and compressors are indispensable in various sectors of the process industry. Here, high demands on the service life of the bearings are of crucial importance, as longer operating times between failures (MTBF = Mean Time Between Failures) are required. Downtimes in production cause considerable costs and lead to a loss of productivity. In addition, manufacturers are striving to develop more compact machines in order to save space.

The requirements for ball and roller bearings are becoming increasingly demanding in order to meet the need for longer service lives and more compact bearings. This can only be achieved with high-quality and reliable bearings.

Depending on the type of pump, bearings must be able to support axial, radial or combined loads at low and high speeds and under different lubrication conditions. The operating conditions are always demanding and a longer MTBF is a challenge for any bearing.

In compressor applications, high axial and radial loads on the bearings must be managed. The bearings play a crucial role as they are responsible for the correct alignment of the rotors in both axial and radial directions. Alignment has a direct impact on the efficiency of the compressor, so the bearings are of paramount importance. It is important to keep the axial and radial vibrations of the bearings as low as possible.

Our application engineers are available to you on site and work closely with OEM research and development departments to find innovative bearing solutions for every phase of your project. Our decades of experience in pump and compressor applications are the key to our joint success.
