About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X50-10S
The AirTAC SAIJ100X50-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 50 mm nominal stroke that can be dialed back by up to 10 mm, giving you a precise 40-50 mm usable travel window for end-position tuning at commissioning. In this bore size, it delivers a robust 7068 N of push force at 0.9 MPa.
This -S variant includes a magnet for position sensing using AirTAC CMSE reed or DMSE electronic switches fitted into the dual-side sensor grooves. The extruded aluminum barrel design omits the FB, CA, CB, and CR mounts, utilizing a reduced SAIJ mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2. Its 25 mm carbon steel rod and M20x1.5 thread handle high side loads well.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X50-10S Is Used
Variable End-Stop Machining
Fine-tune the 40-50 mm travel window on the fly to accommodate varying material thicknesses without swapping out the physical cylinder.
Machine Changeover
Rapidly adjust the end position during product size changes on a packaging line using the rear screw stopper instead of mechanical shims.
High-Force Clamping
Leverage the 7068 N push force at 0.9 MPa to secure heavy workpieces, dialing back the stroke 10 mm to clear clamps before the next cycle.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X50-10S the Right Cylinder?
Select this 100 mm bore actuator when an 80 mm bore lacks sufficient thrust (providing only 3518 N push at 0.7 MPa) or when an 125 mm unit is excessive. The adjustable stroke is chosen over a fixed SAI cylinder when you need a variable end-stop for machine setup or product changeover without bolting on external stops. For a direct ISO 15552 replacement match, specify the 100 mm bore, 50 mm stroke, 10 mm adjustment, PT tapered ports, and the -S magnet.
Because the stroke is short at 50 mm, external guiding is less critical than on longer strokes, but always ensure the load is guided to prevent rod binding. Remember that the rear adjuster acts only as a travel stop to set deceleration, not as a lock; the SAIJ does not hold position without live air. For true load-holding without pressure, consider the SAIL or BSAI series.
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 SAIJ100 Adjustable Cylinder SAIJ100X50-10S FAQ
At an operating pressure of 0.9 MPa, this 100 mm bore double-acting cylinder generates 7068 N of push force and 5497 N of pull force.
The rear adjusting screw acts as an external stopper, allowing you to shorten the effective stroke from 50 mm down to 40 mm, providing a 40-50 mm travel window for fine-tuning without changing the cylinder.
