About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX750-50
The AirTAC SAIJ200X750-50 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a substantial 3204 kgf maximum thrust, making it suited for heavy-duty operations. The integrated rear stopper allows you to trim the effective travel back by up to 50 mm, creating a precise 700 to 750 mm usable window for dialing in final end positions.
This model features a SUS420J2 stainless steel rod for enhanced durability against moisture and wear. It uses PT tapered ports sized at G3/4 and includes variable air cushions at both ends to manage kinetic energy. Since it lacks a magnet, position sensing requires external switches, while the standard sensor grooves on both sides of the extruded aluminum barrel simplify rail mounting.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX750-50 Is Used
Heavy Press Tuning
Dial in the exact 700-750 mm end-stop during heavy press commissioning to accommodate material thickness variations without external shims.
Pallet Changeover
Adjust the retract position on the fly when switching between different pallet sizes on a heavy-duty transfer line.
Large Assembly Setup
Fine-tune the stroke end position for large automotive or machinery assembly jigs where exact clamping distance is critical.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX750-50 the Right Cylinder?
Choose this 200 mm bore cylinder when an application demands extreme force that a 160 mm bore cannot provide, as the 160 mm variant tops out at 2050 kgf. The adjustable stroke is highly beneficial during machine commissioning or product changeovers, allowing operators to fine-tune the 700-750 mm travel window without swapping out the entire cylinder or adding external mechanical stops.
Because the nominal stroke is 750 mm, the M36x2 rod is highly susceptible to side-loading forces; an external guide carriage is strongly recommended to prevent premature seal wear. Remember that the rear adjuster and air cushions function only as travel stops and deceleration devices—they do not hold the load without live air pressure. For fail-safe load holding, consider the SAIL or BSAI series instead. This unit is dimensionally interchangeable with ISO 15552 cylinders and uses the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, 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 SAIJ200AX750-50 FAQ
At the maximum operating pressure of 1.0 MPa, this 200 mm bore cylinder generates 3204 kgf of thrust. At a standard 0.5 MPa, it provides 15708 N of push force and 15080 N of pull force.
The rear adjuster acts as an external stopper screw that lets you shorten the nominal 750 mm stroke by up to 50 mm. This creates a usable travel window between 700 and 750 mm, allowing precise end-position tuning at commissioning without replacing the cylinder.
