About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX1000-30S
The AirTAC SAIJ200X1000-30-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 970-1000mm usable travel window, allowing you to dial back the nominal 1000mm stroke by up to 30mm during commissioning without adding external stops. Built to handle heavy loads, it generates 15708N of push force and 15080N of pull force at 0.5 MPa.
This specific SKU includes a SUS420J2 stainless steel rod (code A) for improved corrosion resistance and a magnetic piston (-S) for position sensing. The extruded aluminum barrel integrates sensor grooves on both sides, accepting AirTAC CMSE reed and DMSE electronic solid-state switches. The G3/4 port and M36x2 rod thread provide robust fluid and mechanical interfaces for high-capacity actuation.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX1000-30S Is Used
Heavy Machinery Setup
Fine-tune the 970-1000mm travel end-stop during initial commissioning of large presses or heavy material handling equipment without machining new hard stops.
Product Size Changeover
Rapidly adjust the retract position on packaging lines when switching between different pallet or product sizes, using the 30mm adjustment window to dial in the exact end point.
Variable End-Stop Tuning
Dial in precise retraction limits for automated assembly stations, leveraging the 21991N push force at 0.7 MPa to move substantial jigs into their exact working positions.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX1000-30S the Right Cylinder?
Selecting this 200mm bore cylinder makes sense when your application requires maximum thrust up to 15708N at 0.5 MPa, or 21991N at 0.7 MPa. If your force requirements are lower, stepping down to a 160mm bore yields 10053N of push force at 0.5 MPa, which might save space and air consumption. The adjustable stroke is ideal for production lines running variable product sizes, where the end-of-stroke position needs frequent fine-tuning without physically swapping the cylinder.
Because the nominal stroke is 1000mm, an external guide is strongly recommended to prevent excessive side-load on the rod and premature seal wear. The rear adjuster acts strictly as a travel stop and deceleration point alongside the air cushions; it does not hold the load without live air pressure. For true fail-safe load holding, consider the SAIL pneumatic lock or BSAI clamp-lock series. This model uses the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets.
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 SAIJ200AX1000-30S FAQ
At 0.5 MPa, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At 0.7 MPa, the push force increases to 21991N.
The rear adjuster screw lets you shorten the effective stroke by up to 30mm, creating a 970-1000mm usable travel window. It functions as a mechanical stop for end-position tuning and is not a lock; the cylinder requires live air to hold its load.
