Steel Bushing

‌1. Material Composition & Design‌

Steel bushings are precision components made from carbon steel or alloy steel, designed for high-load and wear-resistant applications. Key material variants include:

· ‌Carbon Steel‌: ASTM 1045/1060 for general machinery (hardness 35–45 HRC)

· ‌Alloy Steel‌: 4140/4340 with chromium-molybdenum additives for enhanced toughness and fatigue resistance

· ‌Heat-Treated Steel‌: 50CrV4 spring steel hardened to 52–60 HRC for heavy-duty shock absorption

‌2. Manufacturing Processes‌

00001. ‌Forging‌: Free forging or die forging to achieve grain alignment and structural integrity under extreme loads

00002. ‌CNC Machining‌: Precision turning and grinding for dimensional tolerances ≤±0.02 m

00003. ‌Heat Treatment‌:

· Quenching and tempering (e.g., 50CrV4) to optimize hardness and ductility

· Case hardening (e.g., carburizing) for surface hardness up to 60 HRC

00004. ‌Surface Engineering‌: Laser-engraved oil grooves or PTFE coatings to reduce friction in dry conditions

‌3. Performance Characteristics‌

‌4. Industrial Applications‌

· ‌Construction Machinery‌:

· Excavator bucket pins and track rollers, handling shock loads >50 kN

· Bulldozer pivot joints requiring corrosion resistance in abrasive environments

· ‌Automotive Systems‌:
