Description
1. Complies with JS standards;
2. Features an asymmetric bidirectional sealing structure for piston sealing, offering compact dimensions with integrated oil reservoir functionality;
3. Integrated fixed cushions on both end covers minimize impact during directional changes;
4. Multiple rear cover configurations simplify installation and enhance mounting flexibility;
5. Crimped and wrapped assembly ensures robust connection between stainless steel barrel and end covers;
6. Precision-engineered stainless steel barrel provides exceptional strength and corrosion resistance;
7. MF series achieves shorter overall length than ISO6432 standard cylinders while maintaining identical bore/stroke specifications;
8. Comprehensive range of cylinder variants and mounting accessories available for customized solutions.
Category: Adjustable Cylinders | Brand: AirTAC | Series: MFJ Adjustable cylinders
Installation protocol:
Requires 0.5-1.0 N·m torque for port fittings. Lubricate with ISO VG32 hydraulic oil
before initial use. Avoid side-load forces exceeding 15N. For vertical mounting,
recommend using guide mechanism to prevent piston rod deflection.

Ultra-compact aluminum alloy cylinder featuring precision-ground rod and multi-stage buffering system. The MFJ20X70-50S combines 3μm surface-hardened piston rod with double-lip seals for leak-proof operation. Unique dual-bleed screw design allows independent adjustment of cushioning force on both extension/retraction strokes.
Industrial Applications:
- PCB handling robots in electronics manufacturing
- Precision clamping mechanisms for medical device assembly
- Cartesian coordinate actuators in packaging lines
- Automated test equipment positioners
- Food processing conveyor gate controls
Installation protocol:
Requires 0.5-1.0 N·m torque for port fittings. Lubricate with ISO VG32 hydraulic oil
before initial use. Avoid side-load forces exceeding 15N. For vertical mounting,
recommend using guide mechanism to prevent piston rod deflection.
Cycle Life: 5,000 km travel distance (maintenance-free) under standard
conditions (0.5 MPa, 20℃, ISO 8573-1:2010 [3:4:3] air quality)
