drylin® ZLW toothed belt axis with FDA-compliant materials can be cleaned quickly and is maintenance-free thanks to tribopolymer technology from igus®
EAST PROVIDENCE, RHODE ISLAND, UNITED STATES, April 12, 2022 /EINPresswire.com/ — igus, the global manufacturer of engineered motion plastics, has introduced a maintenance-free toothed belt axis specifically designed to improve sanitation in food manufacturing systems. The new drylin ZLW toothed belt axis is based on hygienic design principles and uses FDA-compliant materials.
Cleaning complex machines and systems in food production leads to longer and therefore expensive downtime.
For instance, industrial bakeries are faced with the challenge of regularly cleaning huge vats and mixers, including the moving parts – the linear axes and linear slides on which the mixers are lowered into the containers. If traditional linear axes are used here, there is a high risk that flour and dough residues will be deposited in hard-to-reach places, make cleaning much more difficult and, in the worst case, introduce contamination risks.
“In order to reduce the cleaning of systems in the food industry or even in the pharmaceutical and cosmetics industries, we have now expanded our portfolio of ZLW toothed belt axes,” says Michael Hornung, igus Product Manager for drylin linear and drive technology. “The new model can be cleaned particularly quickly and thoroughly – whether with high-pressure steam jets, chemicals or simply running water. This also increases product safety.”
Based on the hygienic design, cleaning is simplified
The new linear axis is easy to clean because the design engineers at igus followed the guidelines of hygienic design during development. Undercuts in the entire system are minimized where food remnants could accumulate. Likewise, there are no gaps that can occur, for example, if screw heads disappeared into a recess in order to be flush with the surface.
“We deliberately avoided countersinking the screws. True to the motto: “Form follows functionality, in this case easy cleaning,” emphasizes Hornung.
Equally important: rounded corners, which ensure that water can flow better during high-pressure cleaning and carry dirt particles along more easily. Water cannot collect and the formation of germs is reduced. Wherever a dead end was unavoidable, boreholes ensure that liquid drains away completely.
Self-lubricating plain bearings reduce risk of contamination
The igus developers use only FDA-compliant materials for the new toothed belt axis. Both the shaft end supports, and linear carriages are made of corrosion-resistant stainless steel. The plain bearings, on which the carriage moves over the rail are made of the food-grade triboplastic iglide® A160, which enables low-friction dry operation – without external lubricants, which could become a contamination hazard and pollute the environment.
This also makes the drylin ZLW toothed belt axis extremely durable. This is illustrated by approximately 1.5 million double strokes at a speed of 0.5m/s and an acceleration of 2m/s² with a load of 3 kilograms, in igus’ own test laboratory. The drylin ZLW toothed belt axis can now be ordered with a maximum stroke length of up to 3,000 millimeters and can optionally be equipped with a suitable stepper motor.
