A food grade lubricating oil is used for the linear guide ( ), ball screw ( ), bearing ( ), speed reducers ( ) and gears ( ) of these axes. Oil seals ( ) for sealing the food grade lubricating oil are made from a material which is harmless to human bodies, for example, a fluorine resin material, in consideration of their wear.
