Motion plastics specialist igus relies on
lubrication-free liners made of high-performance polymers for a silent and
precise sliding of linear guides. Recently, igus developed an exchange bearing
for the drylin W linear modular kit particularly for a quick replacement of
liners in high-frequency applications. The simple process involves unlocking
the bearing, pushing the liner out, and replacing it. The exchange bearing that
saves time and cost is now also available from Treotham in sizes 16 and 20 for
linear guides of the drylin W series, besides the standard installation size
In extreme circumstances, abrasive sand or glass dust can
cause wear of the liners on a linear guide rail, similar to applications in
automation, where linear guides and axes are in operation around the clock. For
a replacement of the liner, the entire linear carriage needed 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.
igus has now developed an exchange bearing made of the
high-performance plastic iglidur J200 for the drylin W linear guides. The
bearing enables easy replacement directly on the linear rail in a few steps,
reducing downtime, saving set-up costs and ensuring 24/7 operation. A
practical free tool enables safe installation of the liners in no time at all.
To enable even more users to take advantage of the practical and efficient
bearing, the new bearing is also available for installation sizes 16 and 20 in
addition to installation size 10. Thus, for example, drylin W linear guides,
linear axes and linear robots can be easily retrofitted.
bearing replacement in 30 seconds
The principle of the replacement bearing is quite
simple: First, the side cover of the linear housing is loosened using a
screwdriver. With the free tool supplied, which the users can also 3D print
themselves, the liner can now be slid out of the housing and directly removed
from the rail. The new lining made of the wear-resistant and abrasion-resistant
high-performance plastic iglidur J200 is then clipped onto the rail and
inserted into the carriage with the mounting tool. Put the side cover back on
the linear housing and the bearing change is finished in no time. The practical
advantage: The rail is not damaged and the bearing housing can be reused
without disassembly of belts or lead screws. A pin located in the middle of the
side cover secures the liner in the linear housing. Alternatively, replacement
can also be carried out with a screwdriver.
