igubal innovations

With the igubal ESQM-2.0-100 and the ESQM-2.0-150 we are expanding our pillow block bearing series for solar trackers with new versions for 100 and 150mm square profiles and are also introducing a cost-optimised lean version. The bearings were specially developed for tracking solar modules in large-area ground-mounted systems and their spherical bearing position enables angular compensation of up to 14°. The most important further developments of the second generation include a new material with significantly increased UV resistance for long-term outdoor use. At the same time, the profile holder has been changed from V to U alignment, which makes assembly easier. A galvanised sheet metal extender crossbar also reduces the installation height of the upper component by up to 36mm. Additional cut-outs on the dome also allow for neat cable guidance along the profile. In addition to the standard version, the ESQM-2.0-LEAN is a cost-optimised version for projects with defined service life requirements.

In many applications, high static loads are still covered by lubricated metal spherical plain bearings. With our igubal heavy-duty study, we are investigating how applications can be reliably realised with lubrication-free and environmentally friendly polymer spherical plain bearings. The basis is a tribologically optimised interaction of material, geometry and contact surface, which distributes load peaks in a controlled manner and enables strong coefficient of friction. The absence of lubricants prevents dirt particles from adhering and ensures smooth running even under high loads. Applications that have already been realised show that this approach works. In customer projects, lubricated bearing points have been successfully replaced and load capacities of 70kN have been achieved - with reduced maintenance requirements and lower operating costs. Precisely because heavy-duty applications are so individual, we invite users to work with us to develop project-specific solutions - for high static loads, strong impacts and demanding environments.

Now available: Pillow block bearing with quick-release

Tool-free spherical insert bearing change in seconds - the new quick-release pillow block bearing is here. Following a successful prototype phase, the injection moulded version is now ready for batch production and available with no minimum order quantity - currently for a shaft diameter of 25mm.

The spherical insert bearing can be replaced without screws or tools - in just one easy step. This saves time, reduces downtimes and lowers maintenance costs. Tested in the igus laboratory: up to 9kN static pressure load, 100% lubrication-free operation and ideal for modular system concepts in which components have to be adapted flexibly and quickly.

igubal 2.0 – Metallic rod ends with plastic inner ring

With the igubal 2.0 rod ends, we offer maximum flexibility for a wide range of applications. Four iglidur materials, all common thread types and shaft diameters from 6-20mm: The combination of robust metal housing and lubrication-free plastic inner ring enables long-lasting, maintenance-free solutions - without any lubricant.
