Dentists' chairs

Shaft guidance system with self-aligning linear ball bearing: Misalignments are easily compensated

Dentists’ chairs with robust shaft guidance systems

In order to move dentists’ chairs without stick-slip into the correct position, the shaft guidance systems in the vertical adjustment mechanism must be both smooth and robust. Here, the customer can expect a sophisticated range of linear ball bearings, housings, shafts and accessories. The bearings come in lightweight designs with plastic cages or in solid sleeve designs and with corrosion protection (surface coating) if desired. They all have the advantage that they require little space and maintenance.

The high rigidity of the linear ball bearing is an important prerequisite for the required robustness of the design. A further advantage is that they are resistant to cleaning and sterilization processes.
