About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX275-75
The AirTAC SAIJ200X275-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel within a 200-275 mm window. Built with an extruded aluminum barrel, it delivers substantial linear force, generating 21991 N of push thrust at 0.7 MPa. The piston rod is equipped with an M36x2 thread and is manufactured from SUS420J2 stainless steel (code A) for enhanced durability against lateral stress.
This model features PT tapered port threads and dual-sided sensor grooves for flexible mounting of CMSE reed or DMSE electronic switches. The rear adjuster acts purely as a mechanical stop to dial in the exact retract position during commissioning without adding external stops. It is important to note that this adjuster 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 SAIJ200AX275-75 Is Used
Heavy Press Tuning
Dial in the exact 200-275 mm retract position during machine commissioning to perfect heavy pressing operations without external stopper blocks.
Product Changeover
Quickly adjust the end-stop distance by up to 75 mm when switching product sizes on a high-force conveyor line.
Large Assembly Stations
Leverage 21991 N of push force at 0.7 MPa to actuate large tooling, using the rear screw to synchronize multiple cylinder endpoints.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX275-75 the Right Cylinder?
Choose this 200 mm bore when your application demands maximum thrust, as it provides up to 21991 N of push force at 0.7 MPa. If your machinery requires less force, stepping down to a 160 mm bore yields 14074 N at 0.7 MPa, which may offer a more compact and efficient footprint. The 75 mm adjustment range is ideal for product-size changeovers on a line, allowing operators to set variable end-stops rapidly.
Because this is a 275 mm stroke exceeding 300 mm is not an issue here, but the heavy 25 mm rod and M36x2 thread handle high side loads well. Remember that the rear stopper is not a locking brake. When replacing an ISO 15552 cylinder, match the 200 mm bore, 275 mm stroke, PT ports, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). This specific SKU omits the magnet, so position sensing requires adding a -S variant.
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 SAIJ200AX275-75 FAQ
At an operating pressure of 0.7 MPa, this 200 mm bore cylinder generates 21991 N of push force and 15080 N of pull force. It can deliver a maximum push force of 28274 N at 0.9 MPa.
The rear adjuster acts as a mechanical stopper that lets you shorten the 275 mm nominal stroke by up to 75 mm, providing an effective travel window of 200 to 275 mm. It is used for fine-tuning end positions at commissioning and does not lock the load without live air pressure.
