Industrial Grade Hydraulic Brake and Clutch Master/Slave Cylinders for Commercial Vehicles and Passenger Cars
A comprehensive examination of manufacturing precision, material integrity, and global logistics within automotive hydraulic ecosystems.
Automotive braking and clutch actuation systems operating under the OEM standards of Nissan and other global manufacturers require absolute mechanical fidelity. Actuating cylinders—specifically the Brake Master Cylinder, Brake Wheel Cylinder, and Clutch Master/Slave Cylinders—form the vital hydraulic circuit that translates driver mechanical input into high-pressure kinetic force. Components like the Nissan Clutch Slave Cylinder (e.g., 30620-V6311) must withstand constant pressure cycles without seal degradation.
These components are engineered utilizing high-grade nodular cast iron or lightweight anodized aluminum alloys, paired with ethylene propylene diene monomer (EPDM) synthetic rubber seals. This choice of materials ensures resistance to corrosive glycol-based DOT 3, DOT 4, and DOT 5.1 brake fluids, while operating at temperature ranges spanning from -40°C to +120°C.
The international automotive supply chain relies heavily on unified standards. OEM Nissan Qiujing (often known in wholesale commercial structures as Qi/Qiukin brand lines) hydraulic components are distributed globally to meet the demands of fleet maintenance, independent repair networks, and industrial automotive distributors. The shift in global manufacturing networks places high emphasis on IATF 16949:2016 certified facilities that can offer stable production output while maintaining compliance with rigorous Japanese Industrial Standards (JIS) and European ISO metrics.
Wuhu Qiujing Auto Parts Co., Ltd. represents the peak of Chinese precision manufacturing in the automotive sector. Strategically located within Anhui Province's comprehensive automotive industrial cluster (adjacent to major assembly lines and material suppliers), the factory capitalizes on integrated industrial ecosystems.

Hydraulic procurement requires meticulous detail. Below is a structured cross-reference index of some highly requested OEM parts manufactured in our IATF 16949:2016 certified facility, utilizing strict dimensional control and metallurgical verification.
| OEM Part Number | Applicable Vehicle Make | Component Type | Bore Dimension | Material Specification |
|---|---|---|---|---|
| 30620-V6311 / 30620-V6360 | Nissan Pick-up / SUV | Clutch Slave Cylinder | 3/4" (19.05 mm) | Cast Iron G3000 / Hard Anodized |
| 44100-ED010 | Nissan Versa / Tiida | Rear Wheel Brake Cylinder | 11/16" (17.46 mm) | Aluminum Alloy 6061-T6 / EPDM Seals |
| MR980832 | Mitsubishi Triton / L200 | Clutch Slave Cylinder | 13/16" (20.64 mm) | Nodular Cast Iron QT450 |
| 8-97032-847-1 | Isuzu ELF (N-Series) | Clutch Slave Cylinder | 7/8" (22.22 mm) | Heavy-Duty Ductile Iron |
| 47201-28180 / 47201-28240 | Toyota Previa | Brake Master Cylinder | 1" (25.4 mm) | Anodized Aluminum / Reservoir Integrated |

Modern commercial operations demand components that can function reliably under diverse localized scenarios. For instance, cold climate conditions in North America and Northern Europe require brake cylinder boots to maintain flexibility at -40°C to prevent leakage, whereas tropical deployments in Southeast Asia demand high resistance to humidity and salt spray. Our products undergo salt spray testing up to 96 hours to ensure corrosion resistance on external surfaces, while internal bores are polished to a surface roughness of Ra 0.4 microns to ensure minimal seal wear over millions of stroke actions.
