The Schaeffler Group ranks among the leading rolling bearing manufacturers and is a recognised partner for all major automotive, industrial and aerospace manufacturers. The companies belonging to the Schaeffler Group are successful in more than 60 industrial sectors, and have been active in the field of medical technology for some decades.

With the INA and FAG brands, we have a portfolio of components and system solutions that is unrivalled in quality and scope. It includes almost 40,000 catalogue bearings as well as numerous customer-specific special solutions. This portfolio is supplemented by the expertise and special products of strong brands such as Barden and IDAM.

Large production runs and the most up-to-date manufacturing technology available make our products economical. In our global network of engineering centres we develop sophisticated, economical solutions from creative ideas and specific customer requirements.

Angular contact needle roller bearings

Ceiling stands in the operating room have to be able to securely support an increasing number of heavy devices. Preloaded INA angular contact needle roller bearings in pairs make a considerable technical contribution in these circumstances.

In contrast to the ball bearings previously used, the bearing cross-section of these formed rolling bearings is considerably smaller, whereas their static load safety factor and tilting rigidity are significantly higher. The relatively large inside diameter of the bearings means that supply cables and other cables can pass through easily.

Monorail guidance systems for patient couches

An electronic assembly ensures stick-slip-free positioning and smooth running of the patient couch. We supply the mechanical assembly – smooth running monorail guidance systems with high load carrying capacity.

In all areas where loud noise is disruptive, our ‘quiet one’, a four-row linear ball bearing and guideway assembly where the spacers between the balls considerably reduce the running noise, is a truly innovative product. The low displacement resistance enables the couch to be moved with high positioning accuracy. A significant advantage of our solution is that the guidance system operates practically maintenance-free for its entire operating life – even in the standard design. This is due to a lubricant reservoir that is integrated immediately adjacent to the loaded raceways.

Dental bearings for high-speed dental handpieces

A dental handpiece is perhaps one of the most challenging of all bearing applications. The bearing has to operate at speeds of up to 500,000rpm and the handpiece undergoes repeated sterilisation. These conditions, combined with continual build up of operating debris, can cause the bearing to fail more quickly than expected.

By using Barden dental bearings you can extend the operating life of your handpiece and significantly reduce costs. In addition, Barden dental bearings will improve handpiece performance and, due to their low noise characteristics, will minimise patient anxiety.

Direct drives and bearing supports

IDAM direct drives for linear and rotary motion are particularly recommended for medical technology where high precision and dynamics as well as long operating life are required. This involves everything from motors in patient couches to drive units for computer tomography. The Schaeffler Group can supply you with a complete system, including a direct drive and bearing support, from one source and therefore provide you with a significant technology and cost advantage.

Bearing Solutions from Schaeffler: Safety and Flexibility in the OR

The technical equipment used in hospital operating rooms must meet particularly stringent requirements with regard to safety, reliability and flexibility. To that end the contributions made by the bearings that are utilised in these instruments and devices should not be underestimated.
