Vehicle interior – 3 examples of polymer ball bearings in control elements
Sebastian Bloechl | 23. April 2020
The modern car interior has many different knobs, dials and switches. Whether it is the adjustment of the window, air conditioning or sound level – we are increasingly resorting to the cleverly placed rotary adjusters in the interior. All these controls are directly related to the quality perception of the vehicle and can influence a possible car purchase. The physical contact leads to a decision within seconds – do the knobs feel high-quality and are easy to adjust, or are they rather unstable and tend to be inaccurate to adjust? To meet these criteria, the selection of the used bearing solution should be well thought out.
The following 3 examples from the interior are ideal for the use of polymer ball bearings:
Controller for air conditioning system
Air conditioning systems can now be found in almost all new vehicles. Control of the ideal temperature and air flow is a welcome addition in various weather conditions. This is where the thin-ring polymer ball bearings show, among other things, their advantages over metal ball bearings, for example in the areas of costs and design freedom.
Electrical gear lever
Automatic gears are becoming increasingly common in all vehicle classes. The classic gear lever is moved much less frequently in this type of drive, which is why it is replaced by an elegant rotary adjuster in newer combustion engines and electric vehicles. Lubrication-free, lightweight and corrosion-resistant polymer ball bearings are an ideal solution here.
Multimedia Interface (MMI) and additional rotary adjusters
Control elements for the infotainment system are placed on the centre panel in addition to the dashboard. To control the navigation system or favourite music, in addition to the classic rotary movement, there is also a linear movement to confirm the selection made. Since the tribologically optimised polymers are used for xiros® ball bearings, the polymer ball bearing is ideally suited for this application area. The free design offers the possibility of part integration, so that a high-quality latching function can be combined with the rotary movement.
The use of iglidur® plain bearings is also offered for other rotary adjusters – optimised polymers for high-quality and easily adjustable operating elements.
We would be pleased to present you further advantages and applications of our tribologically optimised polymer ball bearings and plain bearings.
