All the benefits of a linear ball bearing system, without the ball
bearings
You get all of the advantages offered by a miniature linear ball bearing
system, plus a bit more, with the new DryLin TK-04 range of miniature
linear bearings from Igus. However, instead of ball bearings, the TK-04
carriage runs on Iglidur J polymer sliding strips, which are maintenance
free, dirt repelling and chemical resistant. Moreover, the replaceable
polymer sliding elements achieve very low friction and wear, are quiet in
operation and require no lubrication.
