About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X650-50
The AirTAC SAIJ100X650-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 600 to 650 mm usable travel window, letting you dial in the exact retract end-position during commissioning without swapping hardware. A standard 650 mm stroke falls within the 1500 mm maximum for this bore, keeping it a catalog item rather than a special order.
Delivering 3927 N of push force at 0.5 MPa (and up to 7068 N at 0.9 MPa), it handles heavy loads via a 25 mm carbon steel rod and M20x1.5 thread. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed or DMSE electronic switches (requires a magnet). Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X650-50 Is Used
Product Changeover
Quickly fine-tune the 600-650 mm retract distance on packaging lines when switching to different carton or pallet sizes without changing the cylinder.
Machine Setup
Dial in the exact end-stop during initial commissioning to perfect a pressing or forming operation, avoiding the need for external shims.
Heavy Material Handling
Leverage the 7068 N push force at 0.9 MPa to move heavy workpieces while retaining the flexibility to trim the stroke by up to 50 mm.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X650-50 the Right Cylinder?
Choose this 100 mm bore when 80 mm (2513 N at 0.5 MPa) is too weak or 125 mm (6136 N) is oversized. The 50 mm adjustment range is ideal for product changeovers where the retract distance varies slightly. Remember, the rear adjuster is a travel stop, not a lock; it cannot hold the load without live air. For positive load-holding, select an SAIL pneumatic lock, a BSAI clamp-lock, or an external rod lock.
To replace an ISO 15552 cylinder, match the 100 mm bore, 650 mm nominal stroke, 50 mm adjustment, PT tapered G1/2 port, and the appropriate mounting bracket. Because the stroke is 650 mm, the 25 mm rod needs external guidance to prevent excessive 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 SAIJ100X650-50 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 acts as a mechanical stop that shortens the 650 mm nominal stroke by up to 50 mm, giving a usable travel window of 600 to 650 mm for fine-tuning end positions.
