About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX100-40S
The AirTAC SAIJ63X100-40-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 1559 N push force at 0.5 MPa, utilizing a G3/8 port and a 20 mm rod. The integrated -S magnet enables position sensing with AirTAC CMSE reed or DMSE electronic solid-state switches housed in the dual-side sensor grooves.
This specific SKU features a 100 mm nominal stroke that can be fine-tuned down by up to 40 mm, creating a flexible 60-100 mm usable travel window. The rod is constructed from SUS420J2 stainless steel (code A) for enhanced corrosion resistance, and the PT tapered port ensures a reliable pneumatic connection. The rear adjuster acts purely as a mechanical stop to set the end position and must not be relied upon to hold a load without live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX100-40S Is Used
Machine Changeover
Dial in the 60-100 mm travel window on the fly during product size transitions without bolting on external stops or changing the cylinder.
Variable End-Stop Positioning
Use the rear mechanical stopper to precisely set the retract end-position during machine commissioning for optimal sensor triggering.
Corrosion-Resistant Actuation
Leverage the SUS420J2 stainless steel rod in humid manufacturing environments to drive 1559 N loads while resisting surface degradation.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX100-40S the Right Cylinder?
Select this 63 mm bore adjustable cylinder when your application requires precise end-position tuning during commissioning or frequent product-size changeovers, avoiding the need to physically swap out a fixed-stroke SAI unit. If your setup demands less thrust, stepping down to a 50 mm bore yields 982 N of push force at 0.5 MPa; stepping up to an 80 mm bore provides 2513 N. Because this model features a 100 mm stroke, the 20 mm rod handles side loads well, but always verify your guiding geometry.
To achieve a true ISO 15552 replacement match, confirm the 63 mm bore, 100 mm stroke, 40 mm adjustment range, PT port thread, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR. Remember that the rear screw stopper and air cushions only decelerate the travel end; for absolute load-holding without live air, integrate an external rod lock or specify a SAIL or BSAI cylinder.

- ✓ 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 SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX100-40S FAQ
At a 0.5 MPa operating pressure, this 63 mm bore cylinder generates 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force increases to 2182 N.
The rear adjuster screw allows you to shorten the 100 mm nominal stroke by up to 40 mm, providing a usable travel window of 60 to 100 mm. It functions as a mechanical stop for end-position tuning and does not lock the load without continuous air pressure.
