About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X550-20S
The AirTAC SAIJ200X550-20-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications. It features a carbon steel piston rod and a rear mechanical adjuster that trims the nominal 550 mm stroke back by up to 20 mm, creating a precise 530-550 mm usable travel window for exact end-position tuning.
Equipped with a magnet for position sensing, it supports AirTAC CMSE reed and DMSE electronic switches mounted in the dual-side sensor grooves. The extruded aluminum barrel incorporates variable air cushions at both ends to manage kinetic energy. The rear stopper acts purely as a travel delimiter to fine-tune the retract position without adding external stops, though it will not hold the load without live air pressure.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15080 N | 15080 N |
| 0.7 MPa | 21111 N | — |
| Max (@1.0 MPa) | 3075 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200X550-20S Is Used
Heavy Press Forming
Dial in the exact 530-550 mm end-stop during heavy press setup to accommodate varying material thicknesses without repositioning the entire tooling.
Product Changeover
Rapidly adjust the retract distance on automated assembly lines when switching between different product sizes, minimizing machine downtime.
Large Mold Handling
Fine-tune the end position of heavy mold transfer systems, ensuring perfect alignment before the final clamping sequence.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X550-20S the Right Cylinder?
Choose this 200 mm bore cylinder when your application requires extreme force, as stepping down to a 160 mm bore drops the 0.5 MPa push thrust to 10053 N. The 530-550 mm adjustable travel window is ideal for product changeovers, allowing you to dial in the exact retract distance without replacing the cylinder. To match this ISO 15552 footprint, specify a 200 mm bore, 550 mm stroke, 20 mm adjustment, PT tapered ports, and the -S magnet option.
Because the usable stroke is 550 mm, long unsupported travel necessitates an external guide to prevent excessive side-loading on the 40 mm rod. Remember that the rear adjuster and air cushions decelerate the load but do not function as a lock; for fail-safe load holding without live air, select an AirTAC SAIL or BSAI cylinder. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ200 Adjustable Cylinder SAIJ200X550-20S FAQ
The operational speed range is 30-500 mm/s.
The rear adjuster allows you to shorten the nominal 550 mm stroke by up to 20 mm, yielding a 530-550 mm travel window. It acts as a mechanical stop for fine-tuning end positions at commissioning, but it is not a lock and requires live air to hold the load.
