Abstract

DC60 roller wheel that this fabricated Looks at the roller wheel Was divided into two parts So that the inside of the wheel The rollers can fit the shaft and bearings inside, and there are also The use of rubber and oil seals and steel seals, each of which has a different function of the seal. Including the intermediate grease between the rubber seal and the steel seal in order to come together. Water, soil, sand to get into the roller wheel. The lubricant is added to the shaft head and has a vent While adding lubricating oil The roller wheel that this fabricated Looks at the roller wheel Was divided into two parts So that the inside of the wheel The rollers can fit the shaft and bearings inside, and there are also The use of rubber and steel shields, each of which has different functions of the shield. Including grease in the middle between the rubber and steel shield to help prevent water, soil, sand that may get into the roller wheel. The lubricant is added to the shaft head and has a vent While adding lubricating oil
