With around 87,900 employees worldwide, Schaeffler FAG is one of the world’s largest technology companies in family ownership and, with approximately 170 locations in more than 50 countries, has a worldwide network of manufacturing locations, research and development facilities, and sales companies. The company generated sales of approximately EUR 13.3 billion in 2016. As a global development partner and supplier, Schaeffler maintains stable long-term relationships with its customers and suppliers.
Schaeffler FAG with its brands INA, LuK, and FAG Bearings has an extraordinarily broad wealth of expertise and all modern technologies needed to achieve the highest levels of economy and precision in manufacturing. This ranges from the high-volume production that predominantly takes place in the Automotive division through to project-based business in Industrial and Aerospace.
In more than 70 plants across the globe, we manufacture high-precision products every day, ranging from 2 mm drawn cup needle roller bearings right through to large rolling bearings with diameters measuring 4.25 meters.
Our Schweinfurt location, for example, is home to one of the world’s largest roll ring forges. Here alone, 80,000 tons of steel are processed every year. At our Herzogenaurach location, more than 520 million finished parts per year are manufactured from 45,000 tons of steel.
Schaeffler FAG with its brands INA, LuK, and FAG is one of the sector’s technological leaders in the areas of cold-forming technology, forging technology, machining, heat treatment, coating technology, and assembly.
Deep drawing, which is a cold-forming process, is among INA and FAG’s core technologies. Our unmatched expertise in the manufacture of high-precision products using forming methods enables us to produce customer-specific solutions in high volumes at an excellent price-performance ratio.
All operations that are relevant to quality, e.g. the grinding and honing (ultrafine grinding) of the inner and outer rings of rolling bearings, are carried out in-house. We have a range of assembly facilities at our disposal – from lean, flexible Chaku-Chaku lines through to highly complex, fully automated production lines – to suit the requirements of the product and the market. This allows us to ensure the consistently high quality standard of our products. In Aerospace, we even go a step further: All stages in the manufacture of every single bearing here are documented and archived.
The increasing complexity of our products in particular – with a wide range of high-precision individual components – requires new production and assembly concepts. Our own Special Machinery and Tool Shop departments work with the production technology specialists to develop and implement solutions that are precisely tailored to suit the requirements of our production facilities. We can thus manufacture in a flexible and economical way.
With the Schaeffler production system, which is very closely based on the idea of lean production, we are continuously making improvements to our quality and delivery reliability – and therefore increasing customer satisfaction – with integrated planning across the entire supply chain combined with lean production technologies and facilities, with a customized operational and organizational structure, and with qualified and independently responsible employees.

FAG Rolling bearings
Rolling bearings generally comprise two bearing rings with integral raceways. Rolling elements are arranged between the rings and roll on the raceways. Rolling elements can be balls, cylindrical rollers, needle rollers, tapered rollers or barrel rollers. The rolling elements are generally guided by a cage that keeps them at a uniform distance from each other and prevents them coming into contact with each other. In needle roller bearings and ribless spherical roller bearings, the cage also ensures that the rolling element axis is positioned correctly. Where bearings can be dismantled, the cage holds the rolling elements together and gives easier fitting of the bearings. For particular applications, rolling bearings with a full complement of balls, cylindrical rollers or needle rollers may be used.
The standard material for sheet metal cages is steel, while brass is also used for some applications. Solid cages are made from brass, steel, laminated fabric and other materials. Cages made from thermoplastic materials are also widely used, especially those made from polyamide reinforced by glass fibre.
Rings and rolling elements are predominantly made from through hardened chromium steel, although case hardening steel is also used. Special bearings for extreme operating conditions – load, speed, temperature, corrosion – are made from temperature-resistant and/or corrosion-resistant steels, plastic, ceramics or other materials.
Rolling bearings are available in open versions or with seals on one or both sides. The most common types of seals are gap seals and lip seals.
Features are application
Every roller bearing design has characteristic features that make it especially suitable for specific bearing applications. It is not possible to draw up generally valid rules for the selection of the bearing type as several factors usually have to be considered and weighed up. In addition to load and speed, attention must also normally be paid to influences such as temperature, lubrication, vibrations, fitting, maintenance etc. In many cases, at least one of the main dimensions of the bearing – usually the bore diameter – is already defined by the design of the adjacent construction.
FAG Rolling bearings for predominantly radial loads are described as radial bearings. Most radial bearings can support combined loads, e.g. deep groove ball bearings, angular contact ball bearings, tapered roller bearings or spherical roller bearings. Cylindrical roller bearings N, NU, most needle roller bearings, drawn cup needle roller bearings and needle roller and cage assemblies can only support radial loads.
Rolling bearings for predominantly axial loads are described as axial bearings. Axial spherical roller bearings and single direction axial angular contact ball bearings can support combined axial and radial loads. The other types of axial bearings are only suitable for axial loads.
If there is little radial space available, bearings with a low cross-sectional height must be selected, such as needle roller and cage assemblies; needle roller bearings with or without an inner ring, deep groove ball bearings and spherical roller bearings of certain series.
FAG Plain bearings
The function of plain bearing arrangements, like rolling bearing arrangements, is to support or guide parts that are movable relative to each other. They must support and transmit the forces occurring in this case. Whereas the bearing arrangement elements in rolling bearing arrangements are separated from each other by means of rolling parts – rolling elements – the movable component in plain bearing arrangements – normally a shaft, stud or strip – slides on the sliding surface of a static bearing bush, bearing cup or sliding strip. The sliding motion occurs directly between the sliding layer of the bearing body and the part that is supported. Lubrication is ensured by embedded lubricants or a solid layer applied to a supporting body. In radial motion, the clearance between the shaft and sliding layer ensures the mobility of the sliding partners.
Rolling and Plain Bearings
Bearings for rotary motion are designed as rolling bearings or plain bearings. A distinction is drawn as to whether the forces occurring between the parts movable relative to each other are transmitted by rolling or sliding elements.
We not only provide FAG industry-leading products, but also the best support in the industry.
