Engineered For Durability: The ZL3.2-300 Crane Sheave Pulley
Our ZL3.2-300 crane sheave is a premium, heavy-duty component engineered for reliability and longevity in demanding lifting environments. Crafted from high-grade #45 steel, this pulley is designed to deliver superior performance and operational safety for 3.2-ton applications. Its advanced heat-treated groove ensures minimal wear and an extended service life, making it a cost-effective and dependable choice for your machinery.
- Product Introduction
Key Features & Benefits
Robust #45 Steel Construction: Forged or cast from high-quality #45 carbon steel, providing exceptional tensile strength, toughness, and fatigue resistance to reliably handle its 3.2-ton rated load.
Advanced Groove Heat Treatment: The wire rope groove undergoes a specialized quenching (heat treatment) process. This creates an exceptionally hard and wear-resistant surface, which dramatically reduces friction, prevents premature wear on the wire rope, and significantly extends the sheave's operational lifespan.
Precision Machining: Expertly machined to precise dimensions, including a 300 mm external diameter and a 90 mm bore sized for a 6210 bearing. This precision ensures a perfect fit, smooth rotation, and efficient load distribution.
Optimized Groove Profile: With a rope groove radius of 8.5 mm (ideal for 16-17mm wire rope), the sheave provides optimal support for the rope, reducing distortion and crushing, and enhancing the safety and durability of your entire lifting system.
