| High Light | +0.004mm Tolerance Tungsten Carbide Cylinder Bore ，High Corrosion Resistance Precision Cylinder Bore ，Mirror-Polished Surface WC-Co Cylinder Bore | ||
In precision mechanical systems where pistons, plungers, or shafts must slide smoothly within a cylinder bore—whether for gas sealing, fluid metering, or high-speed actuation—the dimensional accuracy of the bore is the single most critical factor determining performance, efficiency, and service life.
Our Precision Tungsten Carbide Cylinder Bore is engineered to meet the most demanding sliding fit requirements, with a specified internal diameter tolerance of +0.004mm. This micron-level precision ensures consistent clearance between the cylinder and its mating piston or shaft, enabling smooth, friction-minimized motion while maintaining effective sealing.
Manufactured from premium tungsten carbide (WC-Co) via advanced powder metallurgy, isostatic pressing, and precision diamond grinding, this cylinder bore delivers the exceptional hardness, wear resistance, and dimensional stability required for long-term reliability in compressor systems, gas sealing assemblies, precision pumps, and automation equipment.
| Parameter | Specification |
|---|---|
| Bore Tolerance | +0.004mm / 0 (internal diameter) |
| Cylindricity | ≤ 0.002mm |
| Coaxiality | ≤ 0.002mm |
| Surface Finish (Bore) | Ra ≤ 0.05μm (mirror-polished) |
| Material Hardness | ≥ HRA 90 (up to HRA 93) |
| Cobalt Content | 6.0-20% (grade-dependent) |
| Density | 13.96-14.85 g/cm³ |
| Transverse Rupture Strength | 2,300-4,500 MPa |
| Grain Size | 0.4-2.0 μm |
| Maximum Operating Temperature | Up to 1,000°C |
| Industry | Application | Why This Cylinder Bore |
|---|---|---|
| Compressor Systems | Gas sealing cylinders, multi-stage compressor assemblies | +0.004mm tolerance ensures effective sealing; ≤0.002mm cylindricity maintains consistent clearance |
| Precision Pumps | Metering pumps, plunger pumps, hydraulic cylinders | Mirror-finish bore reduces seal wear; high hardness resists abrasive wear |
| Automation Equipment | Pneumatic cylinders, actuator housings, sliding mechanisms | Long service life reduces maintenance downtime |
| Semiconductor Manufacturing | Precision positioning stages, wafer handling equipment | High dimensional stability in cleanroom environments |
| Oil & Gas | Downhole tool cylinders, wellhead equipment | Corrosion resistance and extended service life in harsh conditions |
| Food Processing | FDA-compliant metering cylinders | Inert material meets sanitary requirements |
Tungsten carbide offers significantly higher hardness (HRA 90+ vs. HRC 40-60 for hardened steel), superior wear resistance (3-5× longer service life), and better dimensional stability under load. The material is also fully corrosion-resistant and maintains its properties at elevated temperatures.
We achieve cylindricity and coaxiality of ≤0.002mm. This ensures the bore remains perfectly round and aligned along its length, which is critical for consistent sliding fit and effective sealing.
We achieve a mirror-polished bore surface with Ra ≤ 0.05μm. This ultra-smooth finish minimizes friction, reduces wear on mating components, and extends service life.
