Airtac SAIJ200 Adjustable Cylinder SAIJ200AX60-40
The AirTAC Airtac SAIJ200 Adjustable Cylinder SAIJ200AX60-40 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 60mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX60-40
The AirTAC SAIJ200X60-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering immense thrust up to 28274N at 0.9 MPa. By integrating a 40mm adjustment mechanism, this model transforms a 60mm nominal stroke into a highly versatile 20-60mm usable travel window. This built-in flexibility allows operators to dial in exact end positions during commissioning without adding bulky external stops.
Constructed with a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance, the extruded aluminum barrel maintains standard ISO 15552 mounting dimensions. The rear adjuster functions strictly as a mechanical stop to fine-tune the retract position, working in tandem with the 50mm variable air cushions to control deceleration. It is not a locking mechanism, meaning live air pressure is required to hold the load in place.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX60-40 Is Used
Heavy Press Tuning
Dial in the exact 20-60mm retract distance for heavy-duty pressing and forming operations during product changeovers.
Machine Setup
Fine-tune the end-stop position at commissioning without the need to swap out the entire cylinder or bolt on external stops.
Variable End Stops
Adjust the travel window on the fly to accommodate different material thicknesses or tooling lengths on a high-force line.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX60-40 the Right Cylinder?
Selecting this 200mm bore size is appropriate when an application demands extreme force, such as 21991N of push power at 0.7 MPa. If the required thrust is lower, stepping down to a 160mm bore provides 14074N at 0.7 MPa, which may better suit medium-duty tasks while saving space. The 200mm bore operates at a speed range of 30-500 mm/s and utilizes a G3/4 PT port.
The adjustable stroke is specifically chosen for machine setups requiring variable end stops or product-size changeovers. Because the stroke is 60mm, which is below the 300mm threshold requiring external guides, the robust 40mm rod diameter and M36x2 thread naturally handle greater side loads. For load-holding without continuous air pressure, this cylinder cannot maintain its position; operators should instead utilize a SAIL (air-released lock) or BSAI (clamp-lock) cylinder. The mounting hardware available includes Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ200AX60-40 FAQ
At 0.9 MPa operating pressure, this 200mm bore cylinder generates 28274N of push force and 15080N of pull force, with a maximum theoretical force of 3204 kgf at 1.0 MPa.
The rear adjuster acts as a mechanical stop that allows you to trim the effective stroke back by up to 40mm, creating a usable travel window of 20 to 60mm to fine-tune the retract end position.
