igus has introduced drylin W Exchange, a new bearing for its drylin W linear system in which the liner can be replaced directly on the rail without dismantling the system. Using a practical assembly tool, users can push the old liner out of the housing, clip the new one on to the shaft and push it into the housing for a flush fit.
“When changing the liner on the linear glides guide rail, for example where extremely abrasive sand or glass dust is present, the entire linear slide has to be pushed off the rail,’’ said Robert Dumayne, director at igus. “For linear axes or multi-axis gantries with a toothed belt drive, this requires a high-assembly effort and long machine downtime.”
The new bearing housing for the drylin W linear system enables easy liner change directly on the linear rail. Users remove the side cover of the bearing housing on the linear slide can with a screwdriver then push the liner out of the carriage. The replacement liner, which is made of wear-resistant and abrasion-resistant iglidur J200 tribopolymer material, is clipped on to the rail and inserted precisely into the slide with the assembly tool. Igus supplies the assembly tool free of charge, and it can be 3D printed.
The new bearing housing can be retrofitted to all existing drylin W systems of size 10 with a shaft, including guides, linear axes, and linear robots. Additional sizes are in the works.
