As a leading manufacturer specializing in sand casting technology, we deliver premium pulley wheels that combine robust construction with precision engineering. Our factory-direct approach ensures competitive pricing while maintaining uncompromised quality standards for industrial applications worldwide.
Superior Material Selection
Our pulley wheels are manufactured using carefully selected materials to meet diverse operational requirements:
Grey Iron Castings (Grades G2500-G3500) provide excellent vibration damping characteristics and superior wear resistance, with Brinell hardness ranging from 187-241. The natural graphite flake structure within grey iron offers inherent lubricity, reducing friction and extending service life in belt-driven applications.
Ductile Iron Components (Grades 65-45-12, 80-55-06) deliver enhanced mechanical properties with tensile strength reaching 80,000 psi and elongation up to 12%. The nodular graphite structure provides improved impact resistance and fatigue strength for demanding industrial environments.
Aluminum Alloys (A356, 319) offer lightweight solutions with excellent corrosion resistance, maintaining structural integrity while reducing rotational mass in high-speed applications.
