Frequently Asked Questions (FAQ)

Q: What is the exact material of this sleeve?
A: It is made from nylon resin conforming to ASTM D4066, which is a specification for polyamide (nylon) molding compounds. The material offers excellent mechanical strength and electrical insulation.
Q: Can I use this sleeve with M16 bolts of any length?
A: Yes, the M16 threaded hole is standard 6H tolerance, compatible with any M16 bolt or stud. However, ensure the bolt length does not exceed the sleeve length to avoid bottoming out.
Q: What is the maximum operating temperature?
A: The sleeve can continuously operate at temperatures up to 120°C, with short-term peaks up to 150°C. For higher temperature requirements, please inquire about our modified materials.
Q: Do you offer custom dimensions or colors?
A: Yes, we can customize outer diameter, length, and thread size according to your drawings. Color options include black, gray, green, or any requested color. Minimum order quantity may apply.
Q: How is the sleeve installed in a concrete sleeper?
A: Simply insert the sleeve into the pre-drilled hole in the concrete sleeper (typically 35.5-36mm diameter). Then insert the M16 bolt through the rail base plate and tighten into the sleeve. The sleeve may be secured with adhesive if required.
Q: Is this product resistant to UV and weathering?
A: Standard nylon has moderate UV resistance. For outdoor applications with prolonged sun exposure, we recommend adding UV stabilizers or using a black color, which provides better UV protection. We can supply UV-stabilized grade upon request.
Q: What is the typical lead time for bulk orders?
A: For standard sizes, lead time is 15-25 days after order confirmation depending on quantity. Custom orders may require 25-35 days. We can expedite for urgent needs.
Q: Do you provide samples before mass production?
A: Yes, we offer free samples (shipping cost borne by buyer) for evaluation. Samples are available from stock for standard sizes.
