About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX155-100S
The AirTAC SAIJ63X155-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to dial back the effective travel. With a 155 mm nominal stroke and a 100 mm adjustment range, it provides a wide 55-155 mm usable travel window for exact end-position tuning during commissioning. It delivers 1559 N of pull force at 0.5 MPa and 2805 N of push force at 0.9 MPa.
This variant includes a magnet for position sensing with CMSE reed or DMSE solid-state switches. It uses an SUS420J2 stainless steel rod for corrosion resistance, PT tapered ports, and variable air cushions at both ends. The rear adjuster acts purely as a mechanical stop to set the travel end and does not hold the load without live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX155-100S Is Used
Variable End-Stop Positioning
Dial in the exact retract distance between 55 and 155 mm during machine setup, allowing rapid accommodation of different part lengths without changing hardware.
Product Line Changeover
Quickly adjust the stroke window on packaging or sorting lines when switching product sizes, using the rear screw to fine-tune the end position.
Sensor-Ready Assembly Press
Leverage the integrated magnet and dual sensor grooves with DMSE electronic switches to confirm rod position during precise assembly operations.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX155-100S the Right Cylinder?
Choose this 63 mm bore adjustable cylinder when an application requires frequent end-stop changes or product-size changeovers, eliminating the need to swap out a fixed-stroke SAI cylinder or bolt on external stops. If your process needs less force, stepping down to a 50 mm bore yields 825 N of pull at 0.5 MPa; if you need more push, an 80 mm bore provides 2513 N.
To replace this cylinder, match the 63 mm bore, 155 mm stroke, 100 mm adjustment, G3/8 PT ports, and the -S magnet. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2. For load-holding without live pressure, select a SAIL or BSAI lock cylinder instead, as the adjuster here is not a brake.
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 SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX155-100S FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 100 mm, creating a usable travel window of 55 to 155 mm. It acts as a mechanical stop for end-position tuning and is not a lock.
At 0.5 MPa, it provides 1559 N of push force and 1402 N of pull force. At 0.9 MPa, the push force increases to 2805 N.
