FAQ
Q1: What is a dual groove pulley?
A: A customized dual groove pulley has two circumferential grooves on its outer rim, allowing it to drive two separate belts from a single power source.
Q2: What materials are available?
A: We offer premium-grade cast iron, ductile iron, aluminum (6061-T6), and steel (1045, 4140) depending on load, speed, and environment.
Q3: Can you customize the bore and keyway?
A: Yes. The bore is precision-machined to your exact shaft diameter, including custom keyways, splines, or set-screw arrangements.
Q4: What industries use dual groove pulleys?
A: heavy duty dual groove pulley is used in industrial machinery, automotive systems, agricultural equipment, material handling, and wind power.
Q5: How does the dual-groove design benefit my system?
A: It allows driving two different loads from one power source, saving space, reducing cost, and simplifying system complexity.
Q6: What balancing standards do you follow?
A: We provide static or dynamic balancing per ISO 1940 standards (G6.3 or G2.5) for high-speed applications over 1000 RPM.
Q7: How do I get a custom pulley designed?
A: Contact Dongpei’s engineering team with your drive parameters (HP, RPM, center distance). They will create a CAD model and drawing for approval.
