Detailed Product Description

On two work surface of a root of cavity guide rail, even drill through definite quantity eyelet, one end of guide rail seal, use air supply from another end is continuously inflating compression air in guide rail cavity, enter into the cavity of guide rail compressed air, will puff from eyelet of work surface. When facies state of inside surface is coincide with glider of work surface of guide rail lay on guide rail, will form a layer of rare air between glider and guide rail, it is called air film or air cushion, to utilize the layer of air cushion as good lubricant, glider can steadily suspend in any place on the up side of air cushion of guide rail surface, thus, glider move on air cushion can not only slide on guide rail surface, but also influence by just air coefficient of viscosity and air resistance, to do relative movement along guide rail, energy loss is very small, thus, will general touch slide friction change into inner friction of air, due to friction cause error to solve in dynamics experiment, have experiment result is close to theory value, thereby enhance experiment accuracy, experimental phenomenon are true, visual and easy accept for students, it is evident in experimental effect.
