Solution
The customer was looking for a solution that would eliminate the disadvantages of the old solution and they found what they were looking for in our plastic bearings. Several rail systems were installed for calf support linear movement. Today,
drylin W single rails and drylin W double rails are used (two WS-10 rails and four WJ200UM-01-10 carriages per calf support).
The advantage of the new polymer bearings in the application are that the systems are not only very lightweight, but also require no lubrication, therefore are completely maintenance-free. This also prevents mechanical failures. And the bearings generate hardly any friction and no noise.
