E4: Extreme-Gliding

New: Versions with enlarged gliding surfaces for extreme applications


For decades, highly wear-resistant igus® plastic e-chains® have been used successfully in thousands of applications. To further increase life in extreme applications, such as very dirty environments or very high fill weights, igus now offers a version with up to 70% larger glide surface.

For long travels

Gliding applications without additional components
(Crossbar and glide surface are made of one piece)

Extremely wear-resistant and quiet through enlarged gliding surfaces (up to 70 %) and 150 % larger wear pad

Life improved by a factor of 4

For high fill weights and high speed

Smooth motion through optimized surface geometry and elastically supported gliding elements

Industries: Crane building, warehouse equipment, equipment manufacturing, gantry robots, mining, power plants, steel plants
