About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX130-75S
The AirTAC SAIJ100X130-75-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that allows you to trim the effective travel down from a 130 mm nominal stroke to a usable window of 55-130 mm. Built with a SUS420J2 stainless steel rod and PT tapered ports, it delivers a robust 3927 N push force at 0.5 MPa. This bore size features a 36 mm cushion length at both ends to manage kinetic energy effectively.
Because this configuration includes a magnet (-S), it supports AirTAC CMSE reed and DMSE solid-state sensors housed in the dual-side extruded barrel grooves. The rear adjuster acts purely as a mechanical stop to fine-tune the retract end-position during commissioning; it is not a load-holding lock. For applications requiring position maintenance without live air pressure, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX130-75S Is Used
Product Changeover
Dial in the 55-130 mm travel window instantly on the production line when switching to a different package size, eliminating the need to physically swap out the cylinder.
End-Position Tuning
Fine-tune the retract end-stop during machine commissioning to achieve exact positioning without machining custom external spacers.
Assembly Pressing
Apply up to 3927 N of push force at 0.5 MPa for pressing operations, while retaining the flexibility to adjust the press depth via the rear screw.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX130-75S the Right Cylinder?
Choose this 100 mm bore when a 63 mm bore (providing 1559 N push at 0.5 MPa) is insufficient, but a 125 mm bore (6136 N push) would be physically oversized. The generous 75 mm adjustment range is ideal for machines processing varying product sizes, allowing operators to dial in the exact end-stop without swapping cylinders or adding external stops. When replacing an ISO 15552 cylinder, match the 100 mm bore, 130 mm stroke, 75 mm adjustment, PT ports, and the -S magnet requirement.
Although the 130 mm stroke is relatively short, the 25 mm rod diameter and M20x1.5 thread provide high rigidity. For any application approaching the maximum standard stroke limits, external guidance is recommended to prevent side-load damage. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, intentionally omitting FB, CA, CB, and CR brackets.
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 SAIJ100AX130-75S FAQ
The rear adjuster screw acts as a mechanical stop that shortens the retract travel. For this model, you can trim the 130 mm nominal stroke back by up to 75 mm, yielding a usable travel window of 55-130 mm without replacing the cylinder.
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. It can deliver up to 7068 N of push force at 0.9 MPa.
