TBM Roller Cutter Hub Housing For Construction Machinery Accessory
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.
| Type of Cutter Hub | Features | Applicable geology |
| Standard Cutter Hub | Overall hardness HRC30 ~ 34, with good bearing capacity; TIMKEN brand bearing. | For hard rock, or not high abrasion geology for the cutter.
|
| Wear-resistant Cutter Hub | the surface is made of re-welded wear-resistant material; TIMKEN brand bearing. | For geology with high abrasive resistance to cutter, such as geology with high quartz content and low compressive strength, use mud-water balance shield. |
| Thicken Wear-resisting Cutter Hub | The cutter body is thickened and the surface is stacked with wear-resistant materials; TIMKEN brand bearing.
| For geology with high abrasiveness and impact on the blade body, and relatively low bearing capacity of the whole blade, such as sand egg formation. |
