About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX130-75
The AirTAC SAIJ63X130-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 130 mm stroke that can be dialed back by up to 75 mm, creating a wide 55-130 mm usable travel window for highly flexible end-position tuning. In the 63 mm bore class, it delivers 1559 N of pull force at 0.5 MPa and 2182 N of push force at 0.7 MPa.
This unit uses a SUS420J2 stainless steel rod (option A) for enhanced durability against moisture and light corrosion. The extruded aluminum barrel integrates sensor grooves on both sides, allowing you to drop in CMSE reed or DMSE electronic switches without extra brackets. PT tapered ports and adjustable air cushions at both ends ensure reliable sealing and smooth end-of-stroke deceleration.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX130-75 Is Used
Variable End-Stop Tuning
Dial in the exact 55-130 mm travel window during machine commissioning to perfectly strike a workpiece without physically remounting the cylinder.
Product Size Changeover
Quickly adapt automated lines to new packaging or part lengths by turning the rear adjuster screw to shorten the stroke on the fly.
Clamping Force Setup
Leverage the 2182 N push force at 0.7 MPa to securely clamp materials, using the wide 75 mm adjustment range to prevent over-travel on delicate parts.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX130-75 the Right Cylinder?
Choose this 63 mm bore adjustable cylinder when your machine requires variable end-stops or frequent product changeovers, as the rear screw stopper allows you to shorten the travel window from 130 mm down to 55 mm without swapping the cylinder or adding external stops. If you need less force, stepping down to a 50 mm bore yields 825 N of pull at 0.5 MPa; if your application requires more power, moving up to an 80 mm bore provides 2268 N of pull. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air—use an external rod lock or SAIL cylinder if position holding is required.
For a true ISO 15552 replacement match, verify the 63 mm bore, 130 mm stroke, up to 75 mm adjustment, PT G3/8 port, and the correct mounting accessory. SAIJ supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, but omits FB, CA, CB, and CR brackets. Because this specific SKU lacks the -S magnet option, it cannot host position sensors without modification.

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 SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX130-75 FAQ
The rear adjuster screw acts as a mechanical stop that lets you trim the effective stroke back by up to 75 mm from the nominal 130 mm, resulting in a usable travel window of 55 to 130 mm. It only sets the end position and does not lock or hold the load without continuous air pressure.
At 0.5 MPa, the SAIJ63X130-75 provides 1559 N of pull force and 1402 N of push force. When operating at 0.7 MPa, the push force increases to 2182 N.
