About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X650-30
The AirTAC SAIJ100X650-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 620-650 mm usable travel window, allowing you to trim the 650 mm nominal stroke by up to 30 mm. This bore delivers 3927 N of push force at 0.5 MPa and up to 7068 N at 0.9 MPa, making it suited for heavy-duty positioning.
It features a G1/2 PT tapered port and a 25 mm carbon steel rod with an M20x1.5 thread. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed or DMSE electronic switches. The rear adjuster acts purely as a travel stop to fine-tune end positions, so live air is still required to hold the load.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X650-30 Is Used
Machine Setup & Changeover
Fine-tune the 620-650 mm travel window during line changeovers to accommodate new product lengths without replacing the cylinder.
Variable End Stops
Adjust the rear stopper to set precise retraction points for heavy product transfer gates on material handling conveyors.
Heavy-Duty Positioning
Leverage 7068 N of push force at 0.9 MPa to move substantial jigs or fixtures, using the adjuster to dial in the final resting position.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X650-30 the Right Cylinder?
Choose this 100 mm bore when a 63 mm bore (offering 2805 N at 0.9 MPa) is insufficient, but a 125 mm bore is excessive. The 30 mm adjustment range is ideal for product changeovers, letting you dial in the exact end-stop without adding external physical stops or swapping the cylinder.
For a fixed-stroke setup without the rear adjuster, the standard SAI cylinder is the alternative. Because the stroke is 650 mm, an external guide is recommended to prevent excessive side-loading on the 25 mm rod. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. If you need true load-holding without live air pressure, consider the SAIL or BSAI series instead.
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 SAIJ100X650-30 FAQ
At 0.5 MPa it provides 3927 N of push force and 3681 N of pull force. At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw lets you shorten the 650 mm nominal stroke by up to 30 mm, creating a 620-650 mm usable travel window. It functions as a mechanical stop for end-position tuning, not a lock, so air pressure must be maintained to hold the load.
