About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX110-50
The AirTAC SAIJ200X110-50 is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, engineered to fine-tune end positions without swapping hardware. It provides a usable travel window of 60-110 mm, letting you trim the 110 mm nominal stroke back by up to 50 mm during commissioning. This bore delivers massive thrust, pushing with 15708 N and pulling with 15080 N at 0.5 MPa. The piston rod uses SUS420J2 stainless steel for superior corrosion resistance, and the PT tapered port threads ensure a tight, reliable seal.
This profile cylinder features an extruded aluminum barrel with sensor grooves on both sides, though this specific SKU omits the magnet, meaning CMSE or DMSE electronic switches cannot be used without modification. The rear adjuster acts purely as a mechanical stop to set deceleration and travel ends; it does not hold the load without live air pressure. For true load-holding without continuous air, consider the SAIL or BSAI series.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX110-50 Is Used
Heavy Press Tuning
Dial in the exact 60-110 mm travel window on heavy stamping presses, allowing precise end-position tuning during setup without replacing the cylinder.
Product Changeover
Quickly adjust the retract stop for different product sizes on a packaging line, trimming the stroke by up to 50 mm to accommodate varying material heights.
Assembly Station Setup
Fine-tune the end-stop on large-scale assembly fixtures to compensate for mechanical wear or tooling variations without adding external physical stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX110-50 the Right Cylinder?
Choose this 200 mm bore when your application demands maximum force, such as 15708 N at 0.5 MPa, and you need the flexibility to dial in the exact end-of-stroke position on the fly. If your thrust requirements are lower, stepping down to a 160 mm bore yields 10053 N of push force, which may be more efficient. The adjustable stroke is ideal for product changeovers where the end-stop varies, eliminating the need to bolt on external stops or replace a fixed SAI cylinder.
When replacing an ISO 15552 cylinder, match the 200 mm bore, 110 mm stroke, 50 mm adjustment range, PT port threads, and basic mounting style. Note that SAIJ uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR options. Because the stroke is 110 mm, side-load risks are minimal, but long unsupported strokes still require an external guide.
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 SAIJ200AX110-50 FAQ
At 0.5 MPa, this 200 mm bore cylinder provides a push force of 15708 N and a pull force of 15080 N. At the maximum operating pressure of 1.0 MPa, it delivers up to 3204 kgf of push force.
The rear adjuster screw lets you shorten the effective stroke from the 110 mm nominal length by up to 50 mm, creating a usable travel window of 60 to 110 mm. It acts as a mechanical stop and does not lock the load without live air pressure.
