: In the carriage and wagon works of Indian southern railways, Perambur, maintenance of railway coaches are carried out in this factory. In that wheels and tyre shop, the wheel bearings and the axle box housings are overhauled. The overhauled parts are then reassembled together. During the process of overhauling, degreasing the roller bearing in a wheels manually (i.e.) directly apply kerosene and compressed air. In manual practice many problems are faced such as time consuming and due to direct contact with chemicals skin diseases like allergy occurs in skin of humans which is caused by the backflow. So, we overcome this problem, we have designed and fabricated a device, that device will mix the chemical like kerosene and compressed air in a closed vessel and it is passed to the outlet nozzle at elevated pressure. That pressurized kerosene-air mixture will reduce the density and remove the grease from the bearing completely and it is collected in a drain. Due to this, the time taken for degreasing is reduced and avoids problem which occurs in a manual method.
