About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX130-50
The AirTAC SAIJ100X130-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel by up to 50 mm. This creates a highly flexible 80-130 mm usable stroke window, letting you dial in the exact retract position during commissioning without adding bulky external stops. It delivers substantial thrust, pushing 5497 N and pulling 3681 N at a 0.7 MPa operating pressure.
This specific configuration utilizes a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. The cylinder operates at speeds from 30-800 mm/s, uses PT tapered G1/2 ports, and includes variable air cushions at both ends to manage deceleration. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX130-50 Is Used
Machine Changeovers
Rapidly adapt the retract end-position for different product lengths on a packaging line without disassembling the pneumatic setup.
End-Stop Tuning
Fine-tune the 80-130 mm travel window during initial commissioning to perfectly align tooling without machining external spacers.
Heavy Forming Operations
Leverage the 5497 N push force at 0.7 MPa for pressing or forming tasks where the exact bottoming position must be dialed in per batch.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX130-50 the Right Cylinder?
Choose this 100 mm bore when a 63 mm bore (providing 2182 N push force at 0.5 MPa) cannot meet your thrust requirements, as stepping up to the 100 mm bore yields 3927 N of push force at the same 0.5 MPa. The adjustable stroke is ideal for product size changeovers on a packaging line, allowing the end-stop to be fine-tuned on the fly instead of physically swapping out a fixed-stroke SAI cylinder.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 130 mm stroke, 50 mm adjustment, PT G1/2 port, and the desired mounting style. SAIJ supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, but omits FB, CA, CB, and CR. Because the rear adjuster is a stop and not a lock, use a SAIL or BSAI cylinder if your application requires fail-safe load holding without live air pressure.
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 SAIJ100AX130-50 FAQ
At a 0.7 MPa operating pressure, this 100 mm bore cylinder provides a push force of 5497 N and a pull force of 3681 N. At the maximum 1.0 MPa pressure, it achieves a push force of 7068 N.
The rear adjuster screw lets you shorten the 130 mm nominal stroke by up to 50 mm, creating an effective 80-130 mm travel window. The adjuster acts as a mechanical stop to set the end position and does not lock or hold the load without continuous air pressure.
