Products & Services
Schaeffler develops and produces high-quality rolling bearings, spherical plain bearings, plain bearings and linear products under the product brands INA and FAG worldwide. Applications in more than 60 industrial sectors and a large number of automotive applications are covered by approx. 40,000 volume-produced catalog products.
The range of maintenance products covers the following areas: Mounting and dismantling, lubrication, alignment, condition monitoring.
The product catalog medias®, the proven selection and information system, contains the INA/FAG catalog products in electronic form and many additional functions. medias® is available in online and offline versions.
X-life is the seal of quality for ultra-high performance products of the brands INA and FAG. They are characterized by higher basic dynamic load ratings compared to conventional products, resulting in a longer rating life and operating life.
Bearing selection and documentation are backed up by modern calculation tools. The software BEARINX® can be used to model and calculate all bearings, complex shafts, shaft systems and even complete gearboxes. This program is also available as BEARINX®-online via the Internet.
The FAG computer program Mounting Manager is a user-friendly aid for ensuring the correct mounting of bearings.
Selection of a suitable lubricant is also part of the comprehensive consultation service. Schaeffler has developed its own range of Arcanol rolling bearing greases comprising a large number of different lubricants.
A direct import of design data into the user’s own CAD system is possible due to the collaboration with TraceParts. 2D drawings and 3D models can be found in the portal "TraceParts online".
The range of training courses from Schaeffler provides comprehensive knowledge about rolling bearings, linear guidance systems and plain bearings. The information and knowledge requirements of employees from varied sectors are covered. Both technically-oriented employees and employees in business administration will find suitable training courses.

Linear Rolling Bearings and Linear Plain Bearings

Linear bearings are bearing elements for translation type motion. As in the case of rotary bearings, a distinction is drawn as to whether the forces occurring are transmitted by means of rolling or sliding elements.

The requirements placed on linear components are as varied as the applications in which they are used. In transport and feed systems, it is mainly speed and accuracy that are required while, in measuring machines for example, the emphasis is more on precision and rigidity. In order to find the right linear guidance system for the specific task, both a sophisticated product range and detailed consultation are important. INA offers both: a wide range of linear products, combined with expert service. Furthermore, a range of accessories precisely matched to applications allow even greater optimisation of the comprehensive standard versions of guidance systems.

Each linear design has particular characteristics that make it especially suitable for particular bearing arrangements. Generally applicable rules for selecting the type of guidance system can only be formulated up to a point, since more and more factors must be taken into consideration and weighed up against each other. Apart from load, acceleration, speed and stroke, factors including temperature, lubrication, vibration, mounting, maintenance etc. must be taken into consideration.

Linear rolling bearings

Linear rolling bearings are available as monorail guidance systems, track roller guidance systems, shaft guidance systems with linear ball bearings, flat cage guidance systems, guidance systems with linear recirculating roller or ball bearing units and as driven units (actuators and tables). Furthermore, INA also manufactures special miniature guidance systems for small design envelopes such as those in mechatronics and precision engineering. These very compact elements with very high load capacity, low friction and high rigidity are available as cage or recirculating systems. Due to their compact design, they can often replace solutions requiring significantly greater space.

Our strong brands INA and FAG stand for premium quality, for our technological leadership and for our high-performance Industrial Aftermarket product and service portfolio that includes more than 40,000 catalog products and enables us to cover solutions for approximately 60 industrial sectors and is unique in its range. Our comprehensive rolling and plain bearing range is rounded out by special designs matched to specific applications and complementary products. System solutions, e.g. for condition monitoring, numerous maintenance tools, mounting services and reconditioning of rolling bearings complete our range.
