The REPA RQ+ rollers represent a new level of quality for the HDPE-roller. Compared to their steel counterparts, our HDPE-rollers have a number of considerable advantages:
We had the HDPE-roller rotate for 200 hours non-stop. During this time, no dust was observed in the bearing.
Voor de watertest is er gedurende 72 uur water tegen de During the water test, water was sprayed against the seal of a continuously rotating HDPE-roller. Neither in the seal nor in the roller, any water was detected.
For measuring the rotation resistance, we had the HDPE-roller make 600 rotations per minute under a radial load of 250 N. The test showed that the final roller resistance was very low, namely 0.96N.0,96N
