Replace quickly while fitted on the rail: Liner replacement with igus exchange bearing

摘要

igus, the motion plastics specialist, relies on lubrication-free liners made of high-performance polymers for a silent and precise sliding of linear guides. At the beginning of the new year, igus developed an exchange bearing for the drylin W linear modular kit, particularly for a quick replacement of liners in high-frequency applications. The principle behind it is quite simple: Unlock bearing, push liner out, replace, and it's ready. The exchange bearing that saves time and cost is now also available in sizes 16 and 20 for linear guides of the drylin W series, besides the standard installation size 10. In extreme conditions, abrasive sand or glass dust can sooner or later cause wear of the liners on a linear guide rail, just like applications in automation where linear guides and axes are in operation round the clock. For a replacement of the liner, the entire linear carriage had to be slid off the rail. Especially for linear axes or multi-axis linear robots with belt drive, this could only be done through costly disassembly and recommissioning.
