Q&A

Part one： (Technical & Product)
Q1: What are the primary applications for CYGM radial piston motors?

A: Our motors are engineered for heavy-duty applications requiring high torque and low speed. This includes marine winches, plastic injection molding machines, construction machinery (drilling rigs/piling drivers), and mining equipment. If your system faces high-impact loads, our 5-star design is the ideal choice.

Q2: Can CYGM motors really handle 55MPa peak pressure?

A: Yes. While standard motors often operate at 25-31.5MPa, our CYGM/GM series is designed with optimized crank-connecting rod structures and heat-treated components, allowing them to withstand peak pressures up to 55MPa in extreme working conditions.

Q3: What types of shafts do you offer?

A: We provide three standard configurations: Involute Spline (standard for most replacements), Key Shaft (for traditional coupling drives), and Internal Spline (commonly used in specialized compact drives). Custom shaft dimensions are also available upon request.

Part two：(Compatibility & Replacement)

Q4: Is it truly "1:1 Drop-in Replacement" for brands like Eaton, SAI, or Danfoss?

A: Correct. We emphasize Functional & Dimensional Compatibility. Our motors match the mounting flanges, shaft dimensions, and oil port positions of major international brands. More importantly, we match the performance curves to ensure your hydraulic system requires zero modification.

Q5: How do I ensure the replacement motor fits my old machine?

A: You only need to provide the original brand and model number (e.g., SAI GM2 or Eaton Staffa STF). Our technical team will cross-reference our database to provide a 3D CAD model for your confirmation before production.

Part three： (Quality & Logistics)

Q6: How do you guarantee batch consistency for large orders?

A: Having been in the industry for over a decade, we know that consistency is more vital than a single perfect sample. We implement 100% Load Testing for every single motor before it leaves the factory. Every unit is traceable via a unique serial number linked to its inspection report.

Q7: What is the typical lead time for an urgent order?

A: We maintain a strategic stock of core components. For standard models, our typical lead time is 15 days. For customized OEM orders, we usually deliver within 30-45 days, significantly faster than many European or American manufacturers.

Part4： (Partnership & Support)

Q8: Do you support OEM or localized assembly (CKD) for distributors?

A: Absolutely. We value long-term partnerships. We offer OEM branding for established distributors to help them build local brand equity. For large-scale partners, we also provide technical support for CKD (Completely Knocked Down) assembly to optimize import duties and lead times.

Q9: What is the warranty policy for international shipments?

A: All CYGM motors come with a 12-month warranty. Since we understand the high cost of international returns, we provide "Service First" support: providing detailed video troubleshooting and fast-tracking free replacement parts (seals/pistons) if a manufacturing defect is identified.
