Precision Ground Arc Groove Tungsten Carbide Shaft Wear Resistant Tungsten Carbide Grooved Cylinder
This tungsten carbide arc groove shaft is a precision-engineered component featuring multiple radiused (arc-shaped) grooves machined into its cylindrical surface, with spherical/radiused ends completing the profile. The unique geometry—a series of precisely spaced, smoothly contoured grooves along the shaft body—serves multiple critical functions in precision mechanical assemblies.
Unlike standard cylindrical shafts or stepped shafts, this component's defining feature is the series of arc-shaped annular grooves that are precisely ground into the outer diameter. These grooves reduce surface contact area, provide channels for lubrication or fluid passage, and enable precise axial positioning or engagement within mating components. The spherical ends eliminate sharp edges, reducing stress concentrations and facilitating smooth insertion or engagement.
Manufactured from premium tungsten carbide (WC-Co) via powder metallurgy, isostatic pressing, and precision diamond grinding, this shaft delivers the exceptional hardness, wear resistance, and dimensional stability required for long-term reliable operation in demanding industrial environments.

An arc groove shaft (圆弧槽轴) is a precision component with multiple radiused grooves machined into its cylindrical surface. It is commonly used as a valve spool, guide pin, flow control shaft, or wear-resistant actuation element in hydraulic, pneumatic, and precision mechanical systems.
The arc grooves serve multiple functions: they reduce surface contact area (reducing friction), provide channels for lubrication or fluid passage, enable precise axial positioning, and allow controlled fluid flow in valve applications.
We achieve diameter tolerances of ±0.002mm standard, groove tolerances of ±0.005mm, and concentricity within ≤0.003mm. High-precision options down to ±0.001mm are available.
