Lubrication-free bearings and reliable cable protection in dental technology

Stick-slip-free movement sequences for treatment units or temperature-resistant moving elements for sintering or melting furnaces. Our energy chains and bearing technology is used, for example, in: dental X-ray systems for adapting to the patient, for guiding media in the adjustment of treatment units, for the smooth adjustment of support and device carriers, in hood furnaces or in machining centres for the production of dental prostheses.


Treatment unit

The dental chair is the heart of every treatment room. Intuitive operation, comfort, ergonomics and low maintenance requirements play an important role here. Bearing technology for linear or rotary adjustments as well as energy chains for guiding media should be as durable and quiet as possible. Stick-slip-free movements must also be ensured for a literally smooth user experience. With our absolutely lubrication-free and maintenance-free surfaces and corrosion-free materials, we meet these requirements. Our energy chain systems for installation in compact devices also ensure reliable guidance of power and data cables.

Dental X-ray machine

In imaging diagnostics in dental medicine today, sophisticated and detailed 360° visualisations can be created. From X-ray devices such as intraoral emitters to 3D tomographs, we offer all components for rotary and linear bearings as well as cable guides. Trouble-free, long-lasting, quietly moving but also economical solutions are important here.
Thanks to optimised coefficients of friction and wear, absolute freedom from lubrication and maintenance, and their high torsional strength, our solutions can be found universally in adjustable, pivoting or rotary bearings in imaging diagnostics. But we also offer a complete range of energy chains and cables for moving applications for the transmission of energy and data within medical devices.

Dental milling machine

Milling machines for CAD/CDM production can be found in the dental laboratory, where they are used to produce dental prostheses with the highest precision. At the heart of the high-tech devices are the two milling heads that process the blank. The guidance of power and data cables to these milling heads must smoothly follow the fine movement sequences without restricting the work process. High accelerations and jerky movements are also among the requirements of cable guides in laboratory equipment. Our product portfolio supports dental laboratories here with energy chains, cables and bearing technology that enable reliable and maintenance-free operation
