      Product details

      Installed in the mixed Cutterhead or hard rock Cutterhead, It crushes the rock through the cutter rings rolling into the rocks in the excavated face. It is mainly used for full face rock strata or some composite formations.


      ● Bearings: TIMKEN?

      ● Floating seal:Trelleborg

      ● Floating seal seat, left and right end cap material: 40CrNiMoA HRC36 ± 3

      ● Mandrel material: 40CrNiMoA HRC42 ± 3

      ● Oil type: Shell SHEL460


      DISC RINGS

      Forgings are made by the closed die method as Germany. Subsequent processing consisting of two machining steps and four heat treatment steps are completed in China.

      The steel manufacturing processes are designed to keep impurities to the lowest.Melting in an Electric Arc Furnace is followed by vacuum degassing. Ingot molds are filled from the bottom with the liquid steel shrouded in argon gas. Exceptionally clean steel ensures high resistance to fatigue, resulting in longer cutter disc life

      BEARINGS

      Carburized and case-hardened, uses Timken tapered roller bearings that outperform other bearings in dynamically loaded conditions and harsh environments. During assembly, the bearings are pre-loaded to effectively excavate hard rock in the most severe operating conditions.

      SEALS

      Durable metal-to-metal face seals eliminate ingress of foreign materials while silicone torics maintain elasticity even at high temperatures.

      RETAINER

      The patented compensation retainer has a superior piston design with a much larger surface area than other cutter manufacturers. The outer surfaces are carburized and case-hardened for extended life in harsh conditions.

      HUB

      Made of durable alloy steel, hubs are furnace heat-treated, quenched, and tempered for toughness. The disc-mounting surface is further induction hardened and finished by grinding.

      SHAFT

      shafts are made of the same alloy steel as the hubs, and go through an identical process of heat-treatment, quenching, and tempering. They are additionally gas nitride for surface hardness
