Compressors and Vacuum Pumps

Compressors and vacuum pumps operate in almost all areas of commerce and industry. ln Schaeffler's large portfolio, you will find the right bearing for every purpose and the largest range of bearings in X-life quality. As a product development partner, Schaeffler also helps to optimize your machines technically and economically with bearing solutions and other components.
 

Central Fields of Application for Compressors 

• Compression of compressed air, both mobile and stationary, for example in factory automation, materials handling, construction machinery, etc.

• Refrigeration compression for industrial and commercial cooling and central air-conditioning systems

• Process gas compression in process engineering, the chemical industry or biotechnology

• Compression in the oil and gas industry, whether upstream, midstream or downstream
   

Areas of Application for Vacuum Pumps

• Generation of negative pressure in packaging technology, for example in the food and pharmaceutical industries 

• High-purity vacuum, dry-running vacuum pumps in the manufacturing process of silicon wafers in the semiconductor industry

• Vacuum as an important component in the chemical industry  

• Simulation and component testing in the aerospace industry

Schaeffler provides high-quality bearings for virtually every compressor application. The portfolio includes the widest range of catalogue bearings, including high precision bearings and the largest range of bearings in X-Iife quality. In addition, there are customised special bearings with individually optimised solutions for special requirements. Schaeffler sets international standards for needle roller bearings and cylindrical roller bearings and in the area of high precision bearings.

The basis for the design of suitable bearing arrangements for compressors is the operating data, primarily the effective bearing forces, speeds and lubrication conditions. The required bearing design, arrangement and load rating derive from this. With our online calculation services, you can carry out your own service life calculations of individual bearings or shaft models in order to select the optimum design and arrangement for you and your application. 

During the concept phase, usually only a few data are available for the calculation of the Rolling Bearings, such as the speed and roughly estimated bearing forces. In order to be able to carry out a simple individual bearing calculation. With this information, Schaeffler offers the option of starting a calculation directly for the selected product. With this tool, you can quickly and easily determine whether the selected bearing is basically suitable for the requirements. Once the design of the compressor is largely complete, a detailed recalculation of the rolling bearings should be carried out on a system basis to ensure that the intended bearings will achieve the required rating life. You can carry out this calculation step-by-step with our Bearinx-online programme.

Furthermore, you will find a Bearing Frequency Calculator (rollover frequencies), a Bearing Selection Assistant, a Grease Selection Tool and the Heating Manager in our Engineering Tools, which will support you during mounting.
