In construction equipment, agricultural machines and offshore installations, bearings often have to cope with extreme conditions, so dirt-resistant components and durable materials are needed. igus has now upgraded its iglidur Q2E heavy-duty bearing to close the gap between existing bearings and products made of metals and composites. The bearing consists of high-performance plastics and is therefore completely lubrication- and corrosion-free. The absence of lubrication allows maintenance-free operation of the bearing points and prevents machine failure due to lack of lubrication. Expensive central lubrication systems are no longer necessary, and dirt and impurities can no longer adhere to the bearing points, minimising wear. In addition, less grease and oil escapes into the environment. Another advantage is that the injection-moulding method used to manufacture the plain bearings is especially cost-efficient.

The iglidur Q2E has a hard polymer shell and a tribologically optimised core of iglidur Q2 in an encapsulated design, ensuring that it can cope even with the most extreme edge loads. When used for a plain bearing with a diameter of 20mm, this material is also very dimensionally stable and wear-resistant even under loads of up to 7t. Functioning as a protective sheath, the shell makes the bearing very sturdy and ensures that it has a longer service life. In a swivel test in igus’s in-house test facilities, the material withstood a radial load of 130MPa. iglidur Q2E is available from Treotham Automation, initially for shaft diameters of 20, 25, 30 and 40mm.
