Franke linear guides are set free of play at the factory.

 

If the given load situation requires it, the game setting can be adjusted later using an integrated grub screw.

Process speeds of up to 10m/s and accelerations of up to 40m/s² can be achieved with Franke linear guides.

Franke linear guides are low-maintenance and have permanent lubrication ex works.

Except for the ball screw drive, no lubrication is required. As a result of the grease escaping via the spindle shaft, relubrication is necessary, depending on the application.

We recommend relubrication with approx. 1–2 g grease at intervals of approx. 700 operating hours.
If necessary, clean the interior and the guideways and coat them with grease.

The sliding resistance depends on how long the linear guide runs in certain sections.
The associated travel speeds are also important here.

 

For a precise determination of the sliding resistance, please contact our technical advisors.

This can be done by reworking the cassette on the underside.

For more detailed information, please contact our technical advisors.

The following parameters are required for the correct design of the linear guide:

  • Choice of arrangement
  • All attacking or arising forces/moments (dynamic/static)
  • Type of load (dormant, swelling, changing)
  • Environmental influences (e.g. temperature, humidity) or special operating conditions (e.g. clean room, vacuum)
  • Travel speed and acceleration
  • Stroke length
  • Target lifespan in km

 

All forces and moments that occur must be within the permissible limits. The relevant data can be found on the respective product page on our website.

The dimensions and the drilling pattern are mostly similar or even identical. The basic load ratings can, however, differ.

Please send us the name of the manufacturer as well as the description and drawing of the corresponding slide for a compatibility check. The dimensions of the sled are then compared with our cassettes.

We would be happy to prepare a service life calculation for you.
