Schaeffler Industrial Aftermarket (IAM), takes care of replacement parts and services for end customers and sales partners. This strong partner provides customers with innovative products and services to increase serviceability and sustained performance of their manufacturing facilities.

In addition to a comprehensive range of rolling bearings, these products include mechanical mounting tools, intelligent online monitoring systems, service and mounting trainings and complete maintenance solutions, tailored to suit the customer’s needs.

INA and FAG rolling bearings for underground applications

Rolling bearings used in the mining sector have to operate under some of the harshest conditions on (and beneath) earth. These unforgiving operating and environmental conditions subject the mining equipment to high stresses, making robust and reliable bearings essential.

Ongoing research and development work, alongside manufacturers and operators of mining equipment, has resulted in a continuous increase in operational safety and operating life of INA and FAG bearings. In terms of total cost of ownership (TCO), Schaeffler engineers consider the entire life cycle of a machine for their calculations, resulting in longer operating life and fewer unplanned downtimes. These solutions help operators to increase machine availability, achieve verifiable savings, and help to reduce the overall costs.

Bearings and solutions for all mining applications

Tough operating and environmental conditions in the mining sector make robust bearings a necessity. Due to ongoing research and development with input from manufacturers and operators, Schaeffler has been able to increase the operational safety and the service life of its INA and FAG bearings. The Schaeffler Group offers the right solution for every application.

Robust bearings for the mining and processing sectors

The machines used in the mining and processing sector need to be able to deal with a variety of conditions. These conditions also affect the bearing selection, as bearing dimensions and designs are mainly determined by the following criteria:

• Load
• Speed
• Environmental factors (for example operating temperature)
• Easy maintenance

For many applications, designers can use standard rolling and plain bearings which can be found in our catalogues. Other applications require special bearings, designed to withstand the special requirements in this industry. The largest of these bearings, which are used in tunneling machines, can have outside diameters of up to 4.25m.
