Solution
The manufacturer, who finally contacted us, replaced the vulnerable system with two
drylin W linear bearings, which now guide the cabin door securely at the top and bottom.
As the glide bars are completely self-lubricating, maintenance is no longer required. In addition, the linear bearings are resistant to dust, moisture and dirt generated when manoeuvring the forklift. The actual problem - the heavy wear caused by increased shocks and vibrations - has also been a thing of the past since the replacement with the resistant drylin linear bearings. The door is firmly fixed in the rails and no longer loosens. Installation of the new rail system is also user-friendly. It can be assembled quickly and easily without special equipment.
