Material & Grades
Glory Rail cast iron pulley is available in a variety of cast iron materials. Cast iron sheave material grades HT200 and HT250 (gray cast iron) are standard, while QT400-15 ductile iron is suitable for applications with higher stress levels. Each material comes with a Material Test Report (MTR) to ensure traceability of composition and mechanical properties.
| Grade | Standard | Tensile Strength (MPa) | Hardness (HBW) | Compressive Strength (MPa) | Application |
|---|---|---|---|---|---|
| HT200 | GB/T 9439-2023 | 200–300 | 170–220 | 720 | Light Load / Auxiliary Lifting |
| HT250 | GB/T 9439-2023 | 250–350 | 190–240 | 840 | Medium Load / General Lifting |
| QT400-15 | GB/T 1348 | ≥400 | 130–180 | — | High Stress / Impact Conditions |
| ASTM A48 Cl.30 | ASTM A48-2003 | ≥207 (30 ksi) | — | — | North America Export Market |
The vibration-damping capacity of gray cast iron is approximately 5 times that of low-carbon steel and 10 times that of aluminum alloy. This characteristic enables **cast iron sheaves** to effectively absorb vibrations during lifting operations, thereby protecting the wire rope and extending the system’s service life. The HT200 grade has a tensile strength of 200–300 MPa and a compressive strength of 720 MPa; the HT250 grade has a tensile strength of 250–350 MPa and a compressive strength of 840 MPa.

Structural Types
Glory Rail offers cast iron groove pulleys in two main structural configurations to accommodate different load and operating conditions:
Spoke Type Cast Iron Sheave
The rim and hub are connected by a spoked structure, which reduces the pulley’s weight while maintaining sufficient strength. It is suitable for medium- and light-duty applications where weight is a consideration, such as electric hoists and light-duty winch trolleys.
Solid Web Cast Iron Sheave
The area between the rim and the hub features a solid web structure, providing greater structural rigidity and load-bearing capacity. It is suitable for medium- to heavy-duty loads, high-impact applications, or harsh operating conditions.
Groove Profile Selection
Selecting the appropriate sheave groove shape is critical to the service life of cast iron sheave wheels.
Use V-shaped grooves for steel wire ropes;
U-shaped grooves for fiber/braided ropes;
round or semicircular grooves for cables;
and trapezoidal grooves for multi-v-belts.
V-shaped or trapezoidal grooves are recommended for heavy-duty equipment to withstand high loads, while U-shaped grooves are recommended for light-duty equipment to reduce wear.
Features of Cast Iron Pulleys
As the best cast iron sheave for industrial use, Glory Rail’s casting crane sheaves offer four key advantages:
Lower Cost: The low cost of raw materials for gray cast iron and ductile cast iron, combined with mature casting processes and short production cycles, gives cast iron sheave factory direct sales a significant price advantage.
Good Castability: Cast iron has good internal fluidity, making it easy to cast complex shapes; its low shrinkage rate reduces internal defects such as shrinkage cavities and gas pores, resulting in castings with greater durability.
Excellent Wear Resistance: Gray cast iron contains 2%–4% carbon and 1%–3% silicon, giving the **Excellent wear resistance cast iron sheave** outstanding wear resistance, making it suitable for high-wear applications.
Good Vibration Damping: The compressive strength of gray cast iron is approximately 3–4 times its tensile strength, while ductile iron has a higher modulus of elasticity and impact toughness, and its vibration-damping properties effectively protect the steel wire rope.
