Customer Benefits
Our hardened teeth sprockets offer extended service life compared to standard sprockets, reducing replacement frequency and operational costs. The precise tooth profile minimizes chain wear and noise, leading to smoother transmission. With customizable bore and keyway, installation is straightforward. Whether you are upgrading existing equipment or building new machinery, these sprockets provide reliable performance under continuous heavy loads. The duplex variant allows for higher power transmission capacity without increasing the sprocket width, ideal for space-constrained applications.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between simplex and duplex sprockets?
A: Simplex sprockets have a single row of teeth for use with single-strand roller chains, while duplex sprockets have two rows of teeth for double-strand chains, allowing higher power transmission in the same width. -
Q: Can the teeth be hardened to a specific hardness level?
A: Yes, we offer induction hardening typically achieving 45-55 HRC. Custom hardness ranges can be discussed based on your application requirements. -
Q: Do you provide custom bore sizes and keyways?
A: Absolutely. We can machine the bore to your exact dimensions, including keyway, set screw holes, and other features. Just provide your drawings or specifications. -
Q: What chain standards are these sprockets compatible with?
A: They are designed to work with ANSI B29.1, ISO 606, and BS standard roller chains. Please specify the chain pitch and type when ordering. -
Q: What is the typical lead time for a custom order?
A: For standard sizes, lead time is 7-15 days. Custom orders with special machining may take 15-25 days, depending on quantity and complexity. -
Q: How do you ensure the quality of the sprockets?
A: We follow ISO9001 procedures, including raw material inspection, in-process checks, and final dimensional and hardness testing. A certificate of analysis is available upon request. -
Q: Can you provide samples for testing before mass production?
A: Yes, sample orders are welcome. We can produce small quantities for your evaluation, and the sample cost is negotiable. -
Q: What is the minimum order quantity (MOQ)?
