Igus has come up with a solution to simplify the replacement of its lubrication-free bearing liners used in linear guide rails. The drylin W Exchange bearing can be replaced directly on the linear rail in just a few seconds, saving both time and money.
Although hard-wearing, the lubrication-free bearing liners used in linear guide rails can become worn when used in the presence of extremely abrasive sand or glass dust. Normally, to replace these bearings the entire linear carriage has to be taken off the rail. And in applications such as multiple-axis linear robots this can entail a lot of assembly work and machine downtime.
The drylin W Exchange bearing solves this problem. Having removed the side cover of the linear carriage, the liner is pushed out of the carriage using the free tool supplied and directly removed from the rail. The new bearing made of wear- and abrasion-resistant high-performance iglidur J200 plastic is then clipped onto the rail and located into the carriage with the mounting tool and the side cover is replaced.
The new Exchange bearing is currently available for retrofit to all existing size 10 drylin W systems, including linear guides, linear axes and linear robots. Further sizes will follow.
