About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX220-50
The AirTAC SAIJ200X220-50 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications, featuring a rear stroke adjuster that creates a 170-220 mm usable travel window. Delivering 15708 N of push force at 0.5 MPa, it handles substantial loads while allowing precise end-position tuning during commissioning without swapping out the entire unit.
This variant features a SUS420J2 stainless steel rod for enhanced corrosion resistance and utilizes PT tapered port threads with a G3/4 connection. The extruded aluminum barrel includes sensor grooves on both sides, and the variable air cushions at both ends work alongside the rear stopper to decelerate massive moving loads smoothly.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX220-50 Is Used
Heavy Press Tuning
Dial in the exact 170-220 mm end position for heavy pressing and forming tasks during initial setup without machining custom spacers.
Product Changeovers
Adapt large automated conveyor lines to different pallet sizes instantly by adjusting the rear stopper up to 50 mm.
Large Assembly Fixtures
Leverage the 15708 N push force at 0.5 MPa to position heavy automotive components, fine-tuning the stroke to match fixture tolerances.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX220-50 the Right Cylinder?
Choose this 200 mm bore cylinder when a 160 mm bore (providing 10053 N push at 0.5 MPa) is insufficient for your load requirements. The 50 mm adjustment range is ideal for production lines running mixed product sizes, enabling rapid changeovers by dialing in the retract end position rather than adding external stops. Remember that the rear adjuster functions strictly as a travel stop and does not hold the load without live air; for true pneumatic locking, consider the SAIL or BSAI series.
Because the 220 mm stroke exceeds the 300 mm threshold, an external guide is recommended to manage side loads on the 40 mm rod. To match this ISO 15552 interchangeable cylinder exactly, specify the 200 mm bore, 220 mm stroke, 50 mm adjustment, PT G3/4 port, and your required mounting style from the reduced SAIJ set: Basic, FA, LB, TC, FTC, TCM1, or 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 SAIJ200AX220-50 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At the maximum 1.0 MPa pressure, it delivers a maximum push force of 3204 kgf.
The rear adjuster acts as a mechanical stop, allowing you to shorten the 220 mm nominal stroke by up to 50 mm, creating a 170-220 mm travel window. It sets the retract end position but does not lock the load without continuous air pressure.
