Custom 20mm Bore Centrifugal Clutch Pulley Factory Casting Services for Manual Applications

As a specialized manufacturer in power transmission components, we provide custom centrifugal clutch pulleys with 20mm bore specifications specifically engineered for manual applications. Our factory casting services combine precision manufacturing with advanced material technology to deliver clutch pulleys that ensure reliable engagement, smooth operation, and extended service life across various manual power transmission systems.

Material Selection and Performance Characteristics

We utilize high-grade aluminum alloys and ductile iron materials specifically chosen for centrifugal clutch applications. Our aluminum alloys (A356-T6) offer excellent strength-to-weight ratio with tensile strength of 234 MPa, reducing rotational mass for quicker response times. The ductile iron components (Grade 65-45-12) provide superior wear resistance with tensile strength of 448 MPa and yield strength of 310 MPa, ensuring durability under repeated engagement cycles.

The material properties are optimized for:

• High thermal conductivity dissipating clutch engagement heat

• Excellent wear resistance against friction material contact

• Superior fatigue strength for long-term reliability

• Optimal balance characteristics for vibration-free operation

• Corrosion resistance for various operating environments
