	TBM Cutter Accessories & Parts
	Litian provides all kinds of TBM disc cutter accessories & parts. The disc cutters use internationally renowned brand TIMKEN bearing and Trelleborg floating seal, which effectively improve the efficiency of hob using. Our factory also can customize the knife box, knife holder, bucket teeth and other accessories for the customer's disc cutter.

	Cutter Ring Tutter ring is made of high-quality mold steel, containing CR, MO, V, NI and other alloy elements. It has high wear resistance, good impact resistance, good quenchability and strong hardness, which can make the whole disc cutter has strong physical and mechanical properties. Cutter Hub(housing) The cutter hub adopts reasonable design, uses high-quality materials, and has suitable hardness. We have developed cutter hubs according to different geological conditions and working conditions in a targeted manner to best suit the requirements of different strata. The roughcast of the cutter hub is forged, which makes the material structure dense and improves the load-bearing capacity. It is processed by CNC machine tools, and the inner holes of the bearing seats at both ends are processed at one time to ensure the machining accuracy, and there is no damage, deformation, severe wear of the cutter hub. Cutter Shaft Using high-quality materials, with suitable hardness and toughness, our cutter shaft can meet different geological needs. Seal retainer Using high-quality seals from well-known brands. The seal has excellent high temperature resistance, reliable sealing performance, meets long-distance use in harsh working environments, and does not cause oil leakage and mud ingress caused by the failure of the metal floating seal. End cover Using high-quality materials, the hardness of the end cover is suitable, which can meet the long-distance use under different geological conditions, and there will be no serious wear of the retainers. Retainer Ring The design of the retainer ring is reasonable, which can meet the long-distance use under different geological conditions, and there will be no situation as breakage and shedding, and the resulting loss of the disc cutter ring, resulting in the failure of the cutter. Cutter Bearing Using heavy-duty tapered roller bearings made by world-renowned brands, which can withstand both radial and axial joint bearing heavy-duty roller bearings. Bearing spacer ring The bearing spacer ring adopts two kinds of plastic and rigid to adapt to different equipment and surrounding rock conditions, to maximize the service life of the bearing and reduce the cost.
