Our igus® lab tests the chip-tightness of energy tubes under realistic conditions.
We tested an RX40.100.100.0 with 100,000 double strokes and 1,000 g of mixed steel chips in a drum.
The result:A total of 0.23 g chips had penetrated into the interior of the tube after 100,000 double strokes while adding 1,000 g of metal chips. No chips were present in the stop dogs or the lids, and the exterior had no apparent scratchmarks or damage.
