• What was needed: drylin® W-profile rail systems, iglidur ® G plain bearing, iglidur ® PRT slewing ring bearing
• Requirements: They were looking for controlled adjustment options that work as quietly and completely lubrication-free as possible and should also be convincing from an aesthetic point of view.
• Industry: Medical technology
• Success for the customer: With the solution consisting of drylin® linear bearing and iglidur® plain bearings as well as a slewing ring bearing for the rotation of the seat, a solution was found that enables a discreet and aesthetically pleasing adjustment and at the same time is acoustically damped and free of any lubricating grease.

This device is used in medicine for the treatment and prevention of back problems associated with the spine. It consists of various adjustable modules for the back, legs and arms and the correct position of the patient, which must be individually adapted to the person.
The manufacturer was looking for a bearing solution for the linear and controlled adjustment of these sets, which should also be as quiet as possible. As the device is used for sanitary purposes and will always be in contact with people, the bearing solutions also had to be completely lubrication-free. Finally, the components also had to be aesthetically pleasing, so the most stylish elements possible were sought for the design of the appliance.

For the realisation of the medical device, the manufacturer decided to use various linear and rotary bearing components from our product portfolio. drylin® W-linear guide including carriage enable the linear bearing of the sets, while iglidur ® G bearings are also used in the adjustable modules on the back and legs.
With this solution, a discreet and aesthetically pleasing linear displacement was achieved, which is also acoustically dampened and free of any lubricating grease. The use of an iglidur ® PRT slewing ring bearing is also planned for the adjustment of the seat, which should be rotated.
