Physiotherapeutic sports equipment: silent and lubrication-free linear adjustment

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.
