D20 bulldozer drive sprocket KM911 201-70-11530

   The sprocket is composed of collar、idler shell、shaft、seal、o-ring、bushing bronze、lock pin plug，the idler is applicable to special model of crawler type excavators and bulldozers from 0.8T to 100T.it is widely applied in bulldozers and excavators of Caterpillar,Komatsu,Hitachi,Kobelco,Kubota,Yanmar and Hyundai etc,have different manufacturing technology,like casting,welding and forging,use precision processing technology and special heat treatment technique to reach best wear-resistance and have maximum extent loading capacity as well as anti-cracking.   The function of an idler is to guide the track links into running smoothly and to prevent dislocation,idlers also carry some weight and therefore increasing groud pressure.there is also an arm in the center which supports the track link and guides the two sides.the smaller the distance between the idler and track roller,the better the orientation.   Our products are according to the standard of OEM to manufacture.

D8T bulldozer segments ring sprocket 3145462 CR7160     The Sprocket belongs to castings, which are first poured, castings tempered, blanks sanded, rail surface quenched, tempered, and machining. technology, like casting, welding and forging, use precision processing technology and special heat treatment technique to reach best wear-resistance and have maximum extent loading capacity as well as anti-cracking.    Our products are according to the standard of OEM to manufacture.

  Motion provided by power generator of an excavator is conveyed to track link by running motor and sprocket rim. The teeth of sprocket rim should fit the track link well and should be able to drive the link steadily. Even when the link stretches due to wear  and uz teat of its pin and bushing, the teeth should fit well usually, a sprocket rim is placed at the back part of the running device of an excavator.   Our products are according to the standard of OEM to manufacture.

  The Sprocket belongs to castings, which are first poured, castings tempered, blanks sanded, rail surface quenched, tempered, and  machining.it is widely applied in bulldozers and excavators of Caterpillar, Komatsu, Hitachi, Kobelco, Kubota, Yanmar and Hyundai etc, have different manufacturing technology, like casting, welding and forging, use precision processing technology and special heat treatment technique to reach best wear-resistance and have maximum extent loading capacity as well as anti-cracking.    Our products are according to the standard of OEM to manufacture.
