About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX250-40
The AirTAC SAIJ200X250-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 210 to 250 mm, allowing you to dial back the 250 mm nominal stroke by up to 40 mm. Built with a SUS304 stainless steel rod, it delivers immense thrust, pushing 21991 N at 0.7 MPa. This extruded aluminum profile barrel includes sensor grooves on both sides for flexible switch placement.
Because this model lacks a magnet, position sensing requires external methods rather than internal CMSE or DMSE switches. The rear adjuster acts purely as a mechanical stop to fine-tune the end position at commissioning without adding external stops. It uses a PT tapered port thread and operates at speeds of 30-500 mm/s.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX250-40 Is Used
Variable End-Stop Tuning
Dial in the exact retract distance within the 210-250 mm window during machine commissioning without swapping out the entire cylinder.
Product Changeover
Quickly adjust the stroke length on packaging or forming lines to accommodate different product sizes on the fly.
High-Force Positioning
Leverage the 21991 N push force at 0.7 MPa to move heavy assemblies, using the rear stop to set the precise end-of-travel location.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX250-40 the Right Cylinder?
Choose this 200 mm bore cylinder when your application demands maximum force, yielding 21991 N of push and 15080 N of pull at 0.7 MPa. If you need less force, stepping down to a 160 mm bore provides 14074 N of push at 0.7 MPa. The adjustable stroke is ideal for machine setups requiring variable end-stops during product changeovers. Since the rear adjuster is a travel stop and not a lock, this cylinder will not hold a load without live air; for fail-safe load holding, consider the SAIL or BSAI series. To match this ISO 15552 interchangeable profile cylinder, specify the 200 mm bore, 250 mm stroke, 40 mm adjustment, PT ports, and your required mounting from the reduced SAIJ set: Basic, FA, LB, TC, FTC, TCM1, or TCM2.
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 SAIJ200BX250-40 FAQ
At a 0.7 MPa operating pressure, this 200 mm bore cylinder generates 21991 N of push force and 15080 N of pull force. It can reach a maximum push force of 28274 N at 0.9 MPa.
The rear adjuster screw lets you mechanically shorten the effective stroke by up to 40 mm from the 250 mm nominal length, providing a usable travel window of 210 to 250 mm. This stopper only sets the end position and does not lock the load without live air pressure.
