Mining and construction machinery are typically found in remote extraction sites, such as mountainous and desert regions, far removed from everyday human habitation; in some cases, they even operate at depths of 2,000 metres below ground. There is a wide variety of such machinery, ranging from mineral crushing equipment to cutting, screening, loading and conveying machinery, all of which operate continuously 24 hours a day. A fault in any of these machines can have a significant impact on production at the mining site; moreover, the increasing size of machinery in recent years has made maintenance work extremely arduous.

Consequently, the operating environments for bearings are characterised by numerous extremely demanding conditions, such as ‘heavy loads plus impact loads’, ‘light loads plus high-speed rotation’, and ‘heavy loads plus low-speed rotation’. Therefore, the bearings sought by users are products that possess the robustness, durability and high reliability necessary to withstand these harsh operating conditions.

To meet these user requirements, OID have consistently integrated our core technologies—namely materials technology, lubrication technology and analytical technology—with state-of-the-art bearing design technology, dedicating ourselves to relevant research and development. As a result, we have achieved the goal of providing products that offer significantly higher levels of ‘long service life and high maximum rotational speed’ compared to previous bearings, thereby contributing to improved production efficiency and reduced maintenance costs for customers operating in harsh mining environments. Furthermore, we offer new solutions that meet environmental protection requirements.
