About Chengdu Hangfa Hydraulic Engineering Co., Ltd. - Robots & Spare Parts Supplier in China

Based in Chengdu, China, Chengdu Hangfa Hydraulic Engineering Co., Ltd. lists seven active products in its catalogue. The company classifies its offerings under Agriculture and Robots & Spare Parts, with the current catalogue focusing on robot mobility components. The listed items include an 8‑inch mecanum wheel (model CMA‑20A), a 650 kg payload mecanum wheel for AGV (CMA‑31), an 8‑inch omni wheel for wheelchair (QLM‑20), a 152.4 mm mecanum wheel for competition robots, a 450 kg payload 10‑inch omniwheel robot kit, a 240 mm omni‑directional wheel for electric AGV, and a 240 kg mecanum wheel for mobile robot (CMA‑25). Each product is identified by its wheel diameter, payload capacity, and intended robotic application. No HS codes are provided in the catalogue.

The product set covers both mecanum and omni‑wheel technologies, which enable holonomic movement for mobile robots, automated guided vehicles and assistive devices. Payload capacities range from 150 kg to 650 kg, and wheel diameters vary between 8 inches (≈203 mm) and 10 inches (≈254 mm). The wheels are typically assembled with an aluminum or steel hub, rubber or polyurethane rollers, and sealed ball bearings to support continuous operation. The catalogue does not specify material grades or certification status, limiting verification to product specifications supplied by the seller.

Product Range and Specialties of Chengdu Hangfa Hydraulic Engineering Co., Ltd.

The catalogue comprises seven wheel variants: mecanum wheels (CMA‑20A, CMA‑31, CMA‑25), omni wheels for wheelchair (QLM‑20) and AGVs (240 mm omni wheel), a competition robot mecanum wheel (152.4 mm), and a 450 kg payload 10‑inch omniwheel kit. Wheel diameters are expressed in inches or millimetres, and payload ratings are stated in kilograms, reflecting typical robot mobility component listings.

In the robotics and material handling industry, mecanum wheels are commonly manufactured with aluminum hubs and polyurethane rollers, offering load ratings from 200 kg to over 1 000 kg and wheel diameters between 100 mm and 300 mm. Standard specifications include ISO‑9001 quality management, IEC‑60204 safety standards for machinery, and bearing ratings of ABEC‑5 or higher. Omni wheels often use a steel or aluminum hub with rubber rollers, and buyers frequently request dimensions, load capacity, bearing type, and IP rating (e.g., IP54 for dust protection).

Trade and Export Information - Chengdu Hangfa Hydraulic Engineering Co., Ltd.

China is a major exporter of robotic mobility components, with shipments of mecanum and omni wheels typically destined for Europe, North America, and Southeast Asian markets. These products fall under HS Chapter 87 (vehicles) or Chapter 84 (machinery parts), where HS codes such as 8708.99 or 8483.90 are commonly used for wheel assemblies. Export logistics usually involve 20‑foot containers holding 200 - 300 units, packed in wooden crates with protective padding.

Importers often require compliance with CE marking for the European Union, UL or CSA certification for North America, and RoHS conformity for electronic equipment. Relevant documentation includes a test report for payload capacity, material safety data sheet (MSDS), and a declaration of conformity. Freight terms are typically FOB Chengdu or CIF destination ports, with buyers arranging inland transport from the nearest major port such as Shanghai or Guangzhou.

Sourcing from Chengdu Hangfa Hydraulic Engineering Co., Ltd. - Buyer Guidance

Buyers should request a detailed data sheet that lists hub material, roller composition, bearing type, IP rating, and load test results for each wheel model. Verification of CE or ISO‑9001 certification, as well as a third‑party load test certificate, helps confirm the wheel’s suitability for high‑payload AGV applications.

Typical minimum order quantities range from 20 to 50 units per wheel type, with lead times of four to six weeks after order confirmation. Packaging is usually in wooden crates with individual units protected by cardboard and bubble wrap, suitable for container loading and handling.

What wheel diameters are available from Chengdu Hangfa?

The catalogue lists diameters of 8 inches (≈203 mm), 10 inches (≈254 mm), 152.4 mm, 240 mm and 240 mm variants, covering the range commonly used in mobile robots and AGVs.

What are the maximum payload capacities?

Payload ratings in the catalogue range from 150 kg for the 8‑inch omni wheel to 650 kg for the CMA‑31 mecanum wheel, with a 450 kg rating for the 10‑inch omniwheel kit.

Which certifications should buyers verify for these wheels?

Buyers should ask for CE marking, ISO‑9001 quality management certification, and a load‑test report; RoHS compliance is also typical for components used in electronic robotic systems.

How are the wheels packaged for export?

Wheels are usually packed in wooden crates with individual units wrapped in cardboard and bubble‑wrap, allowing safe stacking in 20‑foot containers.

What is the typical lead time and minimum order quantity?

Lead times are generally four to six weeks after order confirmation, and minimum order quantities are commonly 20 - 50 units per wheel model.

Which HS codes are relevant for these products?

Robot wheels are generally classified under HS Chapter 87 (e.g., 8708.99) for vehicle parts or Chapter 84 (e.g., 8483.90) for machinery components, depending on the customs authority.

Which markets import these types of wheels?

Major import markets include the European Union, the United States and Canada, as well as Japan, South Korea and other Southeast Asian countries that source robotic automation equipment.
