Buchas de metal duro

Caraterísticas principais:
1. Material Excellence
– Tungsten Carbide Substrate: Ultra-fine grain structure (0.4–1.5 µm) with 6–12% cobalt binder, achieving a hardness of 1,500–2,200 HV (Vickers) and superior wear resistance.
– Corrosion Resistance: Inert to acids, alkalis, and seawater, suitable for harsh chemical or marine environments.

2. Precision Engineering
– Dimensional Accuracy: Tight tolerances (±0.005 mm) for seamless integration with shafts, bearings, and rotating assemblies.
– Surface Finish: Polished (Ra ≤0.4 µm) or ground surfaces to minimize friction and prevent galling.

3. High-Performance Design
– Load Capacity: Withstand radial and axial loads up to 1,500 MPa, ideal for high-stress applications.
– Thermal Stability: Maintain structural integrity at temperatures ranging from -50°C to +800°C.

4. Customization Options
– Coatings: TiN, DLC, or AlCrN coatings for enhanced wear resistance or reduced friction.
– Non-Standard Geometries: Flanged, stepped, or grooved designs tailored to specific machinery.
– Sizes: Inner diameters from Ø1 mm to Ø500 mm, with custom lengths and wall thicknesses.

Applications：
– Oil & Gas: Wear-resistant bushings for drill rigs, pumps, and valve systems in corrosive, high-pressure environments.
– Automotive: Guide bushings for transmission systems, fuel injectors, and suspension components.
– Aerospace: Precision bushings for landing gear, turbine shafts, and hydraulic actuators.
– Industrial Machinery: Bearings for conveyor systems, presses, and CNC equipment.
– Mining: Durable bushings for crushers, excavators, and slurry pumps exposed to abrasive particles. Advantages：
– Extended Service Life: 5–10x longer lifespan compared to steel or bronze bushings, reducing downtime and replacement costs.
– Minimal Maintenance: Self-lubricating properties (optional) and wear resistance eliminate frequent lubrication needs.
– Versatility: Compatible with high-speed, high-load, and corrosive operational conditions.
– Cost Efficiency: Lower total cost of ownership through reduced wear and operational interruptions.

Quality Assurance:
– ISO 9001 Certified: Strict adherence to manufacturing standards for dimensional and material consistency.
– Testing Protocols:
– Dimensional Checks: Laser measurement for ID/OD concentricity and roundness.
– Mechanical Testing: Hardness, TRS, and fatigue resistance validation.
– Environmental Testing: Salt spray, thermal cycling, and abrasion resistance verification.

Customization & Logistics:
– Tailored Solutions: Collaborate with engineers to design bushings for unique load, speed, or environmental requirements.
– Packaging: Anti-corrosion treated, individually wrapped, or bulk-packed for industrial users.
– Lead Time: Standard sizes in stock; custom orders delivered in 3–6 weeks.
