High-precision industrial cylinder with chrome-plated piston rod (hardness HRC 45-55) and aluminum alloy tube. Features wear-resistant guide rings and dual magnetic field sensors slots (compatible with D-A93/D-Z73 sensors). Optimal for medium-load applications requiring precise linear motion control.
- Automated material handling systems
- Plastic injection molding machine ejectors
- Textile machinery tension control
- Semiconductor wafer handling robots
- Automotive assembly line clamping devices
Installation note:
Use 32# hydraulic oil mist lubrication (ISO VG32). Maintain 0.3mm minimum clearance between magnetic sensor and cylinder body. For vertical mounting, install rod end downward to prevent piston sagging.
- Relubricate every 1,000 km stroke distance
- Replace wiper seal every 3 million cycles
- Inspect rod parallelism (max 0.5mm deviation)
