The motion plastics specialist, igus, has added new sizes to its drylin W exchange range. In addition to size ten, the liners are available in sizes 16 and 20 for drylin W linear guides. Developed for quick replacement of liners in high-frequency applications, the liner can be replaced directly on the rail without dismantling the system.
The principle of the replacement liner is quite simple: First, the side cover of the linear housing is loosened using a screwdriver. With the free tool supplied, the liner is pushed out of the carriage and removed. The replacement liner, which is made of the wear- and abrasion-resistant iglidur J200 material, is clipped onto the rail and inserted into the carriage with the assembly tool. Put the side cover back on the linear housing and the bearing change is finished in no time.
The practical benefits of the drylin W exchange are that the rail is not damaged, and the carriage can be reused without dismantling ancillaries of the machine. A pin in the middle of the side cover secures the liner in the carriage. Alternatively, replacement can also be carried out with a screwdriver. On the new liner and in the carriage, igus has provided special recesses for this purpose.
The drylin W exchange, with mounting tool, is easy to order online. Just like the practical retrofit kit with replacement liners, lid and mounting tool.
