Especially for heavy-duty applications in the construction machinery or agricultural industry, igus now has the new tribo-material iglidur TX2 in its product range, which works without lubrication. Because even small excavators still need 50 litres of lubricant every year. The wound plain bearing bushings withstand very strong forces and increase wear resistance by a factor of 3.5 in load ranges with more than 100 MPa surface pressure.
Plastic and heavy loads? This time igus proves that the combination works with a new lead screw nut design. The injection-moulded dryspin JGRM polymer nut offers a cost-effective alternative to ball screw nuts. The new lubrication-free and wear-resistant design can move heavy loads. For higher axial loads, the new lead screw nut is also available with a stainless steel plate as a “Heavy Duty version”.
Defrosting glaciers and declining fish stocks are just two examples of the effects of climate change in Alaska. In order to raise awareness of the issue among the population and to promote alternative drives, the Hoepner brothers from Berlin are developing their amphibious vehicle “Urmel”. They want to travel across Alaska with it. In order for Urmel to be able to drive over hill and dale and ice and snow, light and wear-resistant bearings are required. With the support of igus, the young inventors opted for lubrication-free iglidur tribo-polymers.
With specifications such as low coefficient of friction and excellent vibration dampening, the tribo-polymer iglidur E7 has already proven its strengths in the sliding elements of the drylin linear technology from igus. Now the plastics specialist has also included the material in its plain bearings catalogue range. This also allows users to benefit from iglidur E7 mechanisms with rotating or pivoting movements. The low coefficient of friction of the material ensures smooth movements, reduces the required drive energy and saves additional costs.
In times of increasing digitalisation of factories and warehouses, au-tomated guided vehicles (AGVs) are continuously conquering intralo-gistics. The reliability requirements are high in order to ensure faster processing and unimpeded material flow. AGV manufacturers are therefore equipping their systems with motion plastics components from igus, which make the autonomous vehicles less maintenance-intensive, lighter and more energy-efficient.
