About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X260-20
The AirTAC SAIJ200X260-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 240 to 260 mm, allowing you to dial back the nominal 260 mm stroke by up to 20 mm. Belonging to the 200 mm bore class, it generates a substantial push force of 15708 N at 0.5 MPa and reaches a maximum of 3204 kgf at 1.0 MPa. The robust 40 mm carbon steel rod and M36x2 thread provide high rigidity, though long unsupported strokes still require an external guide to manage side loads.
This model features a PT tapered G3/4 port and dual variable air cushions at both ends to decelerate the heavy payload. The extruded aluminum barrel includes sensor grooves on both sides for installing CMSE reed or DMSE electronic sensors if needed. It supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200X260-20 Is Used
Heavy Press Tuning
Dial in the exact 240-260 mm end-position for large stamping or pressing operations without changing the cylinder.
Product Changeover
Adjust the travel window on packaging lines to handle different sized products quickly during line setup.
Machine Setup
Fine-tune the retract end-stop during initial commissioning to perfect machine kinematics without external stoppers.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X260-20 the Right Cylinder?
Choose this 200 mm bore if you need immense thrust, such as moving from a 160 mm bore that offers 10053 N at 0.5 MPa up to 15708 N. The adjustable stroke is highly beneficial during commissioning or product changeovers, enabling variable end-stops without swapping the cylinder or adding external stops. Note that the rear adjuster acts purely as a travel stop and does not hold the load without live air; for true load-holding, consider an external rod lock, a pilot-operated check valve, or the SAIL and BSAI series. As a dimensionally interchangeable ISO 15552 cylinder, ensure your replacement matches the 200 mm bore, 260 mm stroke, 20 mm adjustment, PT G3/4 port, and standard carbon steel rod. Because the 260 mm stroke exceeds 300 mm, ensure an external guide supports the rod to prevent excessive side-loading.

- ✓ 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 SAIJ200X260-20 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides a push force of 15708 N and a pull force of 15080 N. At the maximum 1.0 MPa pressure, it delivers 3204 kgf.
The rear adjuster screw allows you to shorten the effective travel from the nominal 260 mm down to 240 mm. This creates a 240-260 mm adjustable window for fine-tuning the end position at commissioning without replacing the cylinder.
