Product Introduction
The HOWO stop cylinder is a hydraulic control component used in SINOTRUK HOWO heavy-duty trucks. It is commonly applied in the brake or clutch control system depending on the vehicle configuration. Its main function is to convert hydraulic pressure into mechanical force, ensuring smooth and reliable system operation.
This component plays an important role in vehicle safety and control performance, helping to ensure accurate response during braking or clutch engagement operations. It is widely used in long-distance transport, construction, mining, and heavy-load working environments.
Manufactured with high-strength alloy housing and precision-machined internal components, the stop cylinder offers excellent pressure resistance, stable operation, and long service life. The sealing system is designed to prevent hydraulic oil leakage and maintain consistent performance under high-pressure conditions.
OEM-standard production ensures precise fitment with HOWO hydraulic system mounting points and stable connection with brake/clutch pipelines. Each unit is tested for pressure resistance, sealing performance, and operational reliability before shipment.
