About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX195-75S
The AirTAC SAIJ63X195-75-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster that enables precise end-position tuning. It provides a usable travel window of 120-195 mm, allowing you to dial back the 195 mm nominal stroke by up to 75 mm during commissioning or product changeovers without swapping the unit. Delivering a pull force of 1402 N at 0.5 MPa (and up to 318 kgf at 1.0 MPa), it handles robust actuation tasks.
This variant features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and includes a built-in magnet (-S) for position sensing. It integrates seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches via the dual-side sensor grooves on the extruded aluminum barrel. The adjuster acts purely as a mechanical stop to set the retract end; it does not lock or hold the load without live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX195-75S Is Used
Machine Changeover Setup
Fine-tune the 120-195 mm travel window during product size transitions without replacing the cylinder or adding external mechanical stops.
Variable End-Stop Actuation
Dial in the exact retract position for machining or clamping tasks, leveraging the 1402 N pull force at 0.5 MPa for reliable actuation.
Position Sensing Integration
Utilize the built-in magnet with CMSE reed or DMSE electronic sensors to confirm end-of-travel positions across the adjusted stroke range.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX195-75S the Right Cylinder?
Choose this 63 mm bore when an application requires significantly more force than the 50 mm bore (which offers 825 N pull at 0.5 MPa) but does not need the larger 80 mm frame (2268 N pull). The 75 mm adjustment range is particularly valuable for machines processing variable product sizes, allowing operators to set a new end-stop on the fly. For load-holding without continuous air pressure, this cylinder is not a lock; consider an AirTAC SAIL (air-released lock) or BSAI (clamp-lock) cylinder instead.
When replacing an ISO 15552 cylinder, match the 63 mm bore, 195 mm stroke, up to 75 mm adjustment, G3/8 PT ports, and the -S magnet. Because the nominal stroke is 195 mm (under 300 mm), side-loading is less critical than on longer strokes, but the 20 mm rod and M16x1.5 thread still require external guidance if subjected to heavy lateral loads. Note the SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

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 SAIJ63AX195-75S FAQ
At 0.5 MPa, the 63 mm bore provides 1559 N of push force and 1402 N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers up to 318 kgf.
The rear adjuster acts as a mechanical stop that shortens the effective stroke. For this model, it allows you to trim the 195 mm nominal stroke back by up to 75 mm, creating a usable travel window of 120-195 mm. It does not lock the load without live air.
