About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX60-50
The AirTAC SAIJ200X60-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the nominal 60 mm travel back by up to 50 mm. This yields a highly versatile 10 to 60 mm usable stroke window, perfect for dialing in exact end positions during machine commissioning without adding external stops. It delivers massive thrust, pushing 15708 N and pulling 15080 N at 0.5 MPa, making it suited for heavy-duty pressing and clamping.
This unit features a robust 40 mm carbon steel rod, though this specific SKU is configured with an SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance. The extruded aluminum barrel includes sensor grooves on both sides, and fluid is supplied via PT G3/8 tapered ports. The rear adjuster acts strictly as a travel stop to set deceleration, not as a lock, meaning it will not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX60-50 Is Used
Variable End-Stop Positioning
Dial in the exact end position for heavy-duty material forming operations, adjusting the travel window from 10 to 60 mm without physically unbolting the cylinder.
Machine Changeover
Quickly adapt machinery stroke limits during product size transitions using the rear adjusting screw, drastically reducing setup time compared to fixed-stroke alternatives.
Heavy-Duty Clamping
Leverage the 15708 N push force at 0.5 MPa to secure large workpieces, using the adjustable stop to precisely control the clamping depth.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX60-50 the Right Cylinder?
Choose this 200 mm bore when you need extreme force that smaller neighbors cannot provide; stepping down to a 160 mm bore drops your 0.5 MPa push force to 10053 N. The 50 mm adjustment range on this 60 mm stroke cylinder is ideal for product changeovers on a line, letting you fine-tune the end-stop on the fly rather than swapping out the entire cylinder for a fixed-stroke SAI variant. Because the plain SAIJ design relies on live air to hold position, applications requiring true load-holding without pressure should pivot to the SAIL air-released lock or BSAI clamp-lock cylinders.
When replacing an ISO 15552 cylinder, match the 200 mm bore, 60 mm nominal stroke, 50 mm adjustment, PT G3/8 port, and the desired mounting interface. SAIJ supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. Although the stroke is short, the massive 40 mm rod and M36x2 thread handle high side loads, but any long unsupported travel still necessitates an external guide.

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 SAIJ200AX60-50 FAQ
At a 0.5 MPa operating pressure, the 200 mm bore generates a push force of 15708 N and a pull force of 15080 N. The maximum force at 1.0 MPa is 3204 kgf.
The rear adjuster screw allows you to shorten the effective stroke by up to 50 mm. This provides a usable travel window between 10 mm and 60 mm, enabling fine-tuning of the end position at commissioning without replacing the cylinder.
