About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X300-30
The AirTAC SAIJ100X300-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 30 mm trim range, allowing you to dial the effective travel back from 300 mm to a 270 mm minimum without swapping the unit. Delivering a robust 5497 N push force at 0.7 MPa, it handles heavy linear motion with ease.
This bore features a 25 mm carbon steel rod and a G1/2 port for high airflow. The extruded aluminum barrel includes dual sensor grooves for CMSE or DMSE switches, though this configuration omits the internal magnet. Mounting options span Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB and CA styles.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X300-30 Is Used
Machine Changeover
Dial in the retract stop by up to 30 mm when switching product sizes on a machining line, avoiding the need to swap cylinders or add external shims.
Variable End-Stop Diverter
Fine-tune the actuation endpoint of a heavy diverter arm within the 270-300 mm travel window to perfectly match new package dimensions on the fly.
Heavy Fixture Positioning
Leverage the 5497 N push force at 0.7 MPa to shift heavy pallets, using the rear screw to precisely set the final resting position during line setup.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X300-30 the Right Cylinder?
Choose this 100 mm bore when an 80 mm cylinder (providing 3518 N at 0.7 MPa) lacks the thrust for your heaviest fixtures, but a 125 mm unit is oversized. The 30 mm rear adjuster is invaluable for product changeovers, letting you set a new retract stop during commissioning rather than machining external spacers. Because the adjuster acts only as a travel stop and the air cushions manage deceleration, this cylinder will not hold a load without live air—select a SAIL or BSAI model if rod locking is required.
When ordering for ISO 15552 dimensional interchangeability, confirm the 300 mm stroke, 30 mm adjustment, G1/2 PT ports, and the standard carbon steel rod. Since the stroke is 300 mm, the unsupported rod overhang increases; for heavy offset loads, add an external slide guide to prevent rod side-loading and premature seal wear.
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 SAIJ100X300-30 FAQ
A rear external stopper screw lets you shorten the nominal 300 mm stroke by up to 30 mm, providing an effective travel window of 270 to 300 mm. It acts as a physical end-stop and does not lock the load without continuous air pressure.
At 0.7 MPa operating pressure, it generates 5497 N of push force and 5497 N of pull force. It can deliver up to 7068 N of push force at 0.9 MPa.
