About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX230-50
The AirTAC SAIJ100X230-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 180-230 mm usable travel window, allowing you to dial back the nominal 230 mm stroke by up to 50 mm during machine commissioning. This bore delivers 3927 N of push force and 3681 N of pull force at 0.5 MPa, making it well-suited for heavier handling tasks.
This specific configuration uses a SUS304 stainless steel rod (option B) for superior corrosion resistance and includes PT tapered port threads. The extruded aluminum barrel incorporates sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic sensors. The rear adjuster acts purely as a travel stop to fine-tune end positions without adding external stops.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX230-50 Is Used
Machine Changeover
Fine-tune the 180-230 mm travel window during product size changes to set new end positions without swapping hardware.
Heavy Clamping
Leverage 3927 N of push force at 0.5 MPa to secure heavy workpieces, using the rear stop to dial in the exact clamping depth.
Conveyor Diverter
Adjust the retract end-position on the fly to accommodate different package sizes moving down an assembly line.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX230-50 the Right Cylinder?
Choose this 100 mm bore when a 63 mm cylinder (providing 1559 N push at 0.5 MPa) is insufficient, but an 80 mm bore (2513 N) leaves no room for growth. The 50 mm adjustment range is ideal for product changeovers where end-position tuning is required without physically swapping the cylinder. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR.
Because the stroke is 230 mm, an external guide is recommended to manage side loads on the M20x1.5 rod thread. Remember that the rear adjuster is a stop, not a lock; the SAIJ does not hold loads without live air. For load-holding without pressure, consider the SAIL or BSAI series. To match this exact SKU for an ISO 15552 replacement, specify bore 100, stroke 230, adjust 50, PT ports, SUS304 (B) rod, and no magnet.
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 SAIJ100BX230-50 FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster screw lets you shorten the effective travel from the 230 mm nominal stroke down to 180 mm. It acts as a mechanical stop to tune end positions, but it does not lock or hold the load without live air pressure.
