HQW Precision has supplied super precision miniature ball bearings to a mirror system which will be installed on the worlds most powerful telescope. The ELT (Extremely Large Telescope) project will begin operation in 2025 and aims to answer many of the unanswered questions about the Universe.

Construction is underway in Chile to build the largest optical/mid-infrared telescope in the world. The ELT (Extremely Large Telescope) is scheduled to begin operation in 2025 and will be able to gather more information than ever before, vastly expanding our knowledge of the Universe. HQW is supplying super precision miniature ZKLN bearings to the project, which will be used in the accurate adjustment of the 800 mirrors positioned within the telescope.

These bearings are double row, axial contact ball bearings which provide very high axial stiffness, making them ideal for applications such as this where positional accuracy is essential. Stefan Vogel, Sales & Application Manager at HQW Precision said: “We are very proud to be contributing to this project. The ELT is a hugely important facility which will hopefully answer many of the questions we have about the Universe. Accurate positioning of the mirror system is vital in ensuring the best quality data can be gathered and HQW precision bearings have been optimally designed to offer this.”
