**Product Overview**:
The single splined shaft flange type Hydraulic Cylinder is a high-precision and high-rigidity Hydraulic Actuator. It adopts an integrated design of splined shaft and flange, which can not only transmit axial thrust but also resist torsion. This product is suitable for applications that need to withstand both axial loads and torque simultaneously, and is widely used in high-load industrial fields such as injection molding machines, die-casting machines, metallurgical equipment, and heavy machinery.

### **Core Features**
1. **High Load Capacity**
- The spline shaft design effectively transmits torque, and the flange structure disperses axial loads, ensuring stable operation of the cylinder under high pressure (up to 40 MPa).
2. **Precise Alignment**
- Single keyway shaft guiding and mating flange plate positioning prevent rotational deviation, with a repeat positioning accuracy of ±0.1mm. It is suitable for precision press-fitting, mold closing, and other scenarios.
3. **Compact Integration**
- The spline shaft and the piston rod of the oil cylinder are integrated into one structure, reducing additional transmission components, saving installation space, and lowering system complexity.
4. **High Rigidity Sealing**
- Multi-layer combined seals (such as a Stellite seal + a Grease seal) are adopted to prevent leakage and wear, and are suitable for high-frequency reciprocating motion and shock loads.
5. **Flexibility and Adaptability**
- The flange supports ISO/SAE standard hole positions or custom processing, and the splined shaft can be matched with involute/rectangular splines (DIN/GB/JIS standards).

### Typical Application Scenarios
- **Plastic Machinery**: Clamping mechanism of injection molding machines, thrust devices of extruders.
- **Metal Processing**: Ejection systems of die-casting machines, mold positioning of punch presses.
- **Metallurgical Equipment**: Pinch rolls of continuous casting machines, down-pressure devices of rolling mills.
- **Heavy Machinery**: Thrust systems of shield machines, main cylinders of hydraulic presses.
