Oil windows: Insights into the gearbox interior

Oil windows provide a clear view of the oil flow and level indicators. The glasses made of Ihrlerstein allow you to precisely detect and read fluid levels. They are ideal for gearboxes or wheelset bearings, for example. Metalltechnik Dechant uses temperature and pressure-resistant glass to withstand the increased mechanical influence.
