About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX105-20
The AirTAC SAIJ200X200-20 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. This 200mm bore actuator delivers massive thrust, pushing 21991N and pulling 21344N at 0.7 MPa. By turning the rear stopper screw, you can fine-tune the effective travel window from 85 to 105mm during commissioning without adding external stops.
This variant features a SUS420J2 stainless steel rod and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic switches. The rear adjuster acts strictly as a travel stop and deceleration point; it does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX105-20 Is Used
Press Tooling Setup
Dial in the exact end-position for heavy stamping or forming tools, trimming the stroke down to 85mm to accommodate die height variations.
Product Changeover
Quickly adjust the retract end-stop on a packaging line when switching to a different product size, avoiding the need to physically swap cylinders.
Heavy Material Handling
Move substantial loads with up to 3204 kgf maximum thrust capacity while maintaining the ability to fine-tune the travel distance.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX105-20 the Right Cylinder?
Select this 200mm bore model when a fixed-stroke SAI cylinder cannot accommodate minor mechanical variations or product changeovers. If your application requires less force, stepping down to the 160mm bore yields 14074N push force at 0.7 MPa, which may suffice for lighter tooling. For load-holding requirements without continuous air pressure, this standard SAIJ is insufficient; consider the SAIL pneumatic lock or BSAI clamp-lock variants instead.
When replacing an ISO 15552 cylinder, match the 200mm bore, 105mm stroke, 20mm adjustment range, G3/4 port, and your required mounting accessory from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because this SKU lacks the -S magnet suffix, it cannot host internal sensors; specify -S if position feedback is needed. Although the stroke is only 105mm, the 40mm rod diameter and M36x2 thread handle high side loads well, but external guides remain essential for heavy tooling.
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 SAIJ200AX105-20 FAQ
At an operating pressure of 0.7 MPa, this 200mm bore cylinder provides a push force of 21991N and a pull force of 21344N. It can deliver up to 3204 kgf at 1.0 MPa.
The rear adjuster screw allows you to shorten the nominal 105mm stroke by up to 20mm, creating a usable travel window of 85 to 105mm. This stopper only sets the end position and does not lock the load.
