FAQ

Q1: How do you package the hydraulic cylinders? Is it safe for international shipping?
A: Yes, we use strong and secure packaging based on the order and transportation type. Wooden cases, cartons, and pallets are commonly used. Each cylinder is wrapped to prevent damage during transit and labeled clearly for easy identification.

Q2: Is installation complicated? Do you provide installation guidance?
A: Our cylinders are designed for direct replacement with original equipment. We can provide basic installation tips, technical drawings, and video guides to assist your team. If needed, our engineers are available for further support online.

Q3: What kind of seals do you use in your cylinders?
A: We use high-quality imported seals such as NOK (Japan) and SKF (USA), which ensure long-lasting performance and excellent resistance to pressure and temperature. If you need specific seal brands, we can also customize based on your request.

Q4: Will your cylinder fit my excavator if I don't have the OEM part number?
A: Don’t worry. Just provide us with your excavator brand and model, plus photos or measurements (e.g. pin-to-pin length, bore size, rod diameter). Our sales engineers will match the correct cylinder for you.

Q5: Can you support us technically if we have special working conditions (e.g. extreme heat, heavy-duty use)?
A: Absolutely. With over 16 years of experience and our own factory, we can offer custom material selection, reinforced designs, and technical consultation to ensure your hydraulic cylinders perform reliably in any working environment.
