Adjustments of wheelchairs, fitness and rehabilitation equipment should be light, quiet and soft, over and over again. The use of igus plain bearings and linear systems offers the user a comfortable, high-quality feeling in the adjustment and due to the completely lubrication-free operation, all bearing points are clean and robust. Our bearings also show these advantages for prostheses and orthoses, which should feel as natural as possible. Our iglidur plain bearings withstand sustained high loads, impacts and dirt, even with thin walls, with a long service life with low coefficients of friction and without a slip-stick effect. Our e-chains and cables ensure safe energy supply even in confined spaces in electrical adjustments of sports equipment.
