About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX65-30
The AirTAC SAIJ200X65-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end-of-travel position. With a nominal 65mm stroke and a 30mm adjustment range, it provides a usable travel window of 35-65mm to dial in exact positioning during machine commissioning. It delivers massive thrust, generating 15708N of push force and 15080N of pull force at 0.5MPa.
This heavy-duty actuator features a 40mm SUS420J2 stainless steel rod and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic sensors. The rear adjuster acts purely as a mechanical stop for deceleration; it does not hold the load without live air pressure, so for true load-holding you would need a SAIL or BSAI lock cylinder.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX65-30 Is Used
Heavy Press Changeover
Dial in the 35-65mm travel window during product-size changeovers on heavy pressing lines without swapping the actuator.
Adjustable End Stops
Use the rear stopper screw to fine-tune the retraction end position during machine commissioning for multi-tier part ejection.
Massive Force Positioning
Leverage 15708N of push force at 0.5MPa to move heavy pallets or stamping components while trimming the stroke up to 30mm.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX65-30 the Right Cylinder?
Choose this 200mm bore actuator when your application requires extreme force and precise end-position tuning without adding external stops. If you need less force, stepping down to the 160mm bore yields 10053N of push force at 0.5MPa. The 40mm rod and M36x2 thread provide high rigidity, but because the 65mm stroke is relatively short for this massive bore, side-load risks are minimal compared to longer strokes. The rear screw allows up to 30mm of retraction adjustment, making it ideal for product-size changeovers.
As an ISO 15552 profile cylinder, it is dimensionally interchangeable with standard ISO 15552 mounting interfaces. It uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. It operates at speeds of 30-500mm/s with variable air cushions at both ends. Since no -S magnet is specified, it ships without sensor capability unless upgraded.
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 SAIJ200AX65-30 FAQ
At 0.5MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. It can reach a maximum push force of 28274N at 0.9MPa.
The rear adjuster screw lets you shorten the 65mm nominal stroke by up to 30mm, creating a usable travel window of 35-65mm. The adjuster acts as a mechanical stop and does not lock or hold the load without continuous air pressure.
