Airtac SAIJ50 Adjustable Cylinder SAIJ50AX230-10
The AirTAC Airtac SAIJ50 Adjustable Cylinder SAIJ50AX230-10 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø50mm bore and 230mm stroke, G1/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX230-10
The AirTAC SAIJ50X230-10 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 220 to 230 mm, allowing you to dial back the nominal stroke by up to 10 mm during commissioning. With a 50 mm bore, it delivers 982 N of push force and 825 N of pull force at 0.5 MPa operating pressure.
This variant uses a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance and features PT tapered port threads (G1/4). The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic sensors. The rear adjuster acts purely as a mechanical stop to fine-tune the end position without adding external stops, and it does not hold the load without live air pressure.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX230-10 Is Used
Machine Setup Calibration
Dial in the exact 220 to 230 mm end-position during initial commissioning without swapping out the entire cylinder or adding external stopper blocks.
Product Changeover
Quickly adjust the retract distance by up to 10 mm on a packaging line when switching between slightly different product sizes.
Clamping Force Control
Fine-tune the travel limit on a clamping fixture to prevent overtravel and adapt to varying material thicknesses.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX230-10 the Right Cylinder?
Select this 50 mm bore cylinder when an application requires 982 N of push force at 0.5 MPa, offering a middle ground between the 40 mm bore (628 N) and the 63 mm bore (1559 N). An adjustable stroke is ideal for machine setups requiring precise end-position tuning or product changeovers, providing flexibility that a fixed-stroke SAI cylinder cannot offer.
For ISO 15552 replacement matching, ensure you specify the 50 mm bore, 230 mm stroke, 10 mm adjustment range, PT port thread, and SUS420J2 rod material. Since the 230 mm stroke exceeds 300 mm, external guiding is not yet critical, but always ensure the M16x1.5 rod thread handles the expected side loads. Note that the rear adjuster and air cushions only decelerate the travel end; for load-holding without live air pressure, consider an AirTAC SAIL or BSAI cylinder.
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 SAIJ50 Adjustable Cylinder SAIJ50AX230-10 FAQ
At 0.5 MPa operating pressure, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers up to 200 kgf of thrust.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke by up to 10 mm, creating a 220 to 230 mm usable travel window. It is a travel stop for fine-tuning end positions, not a lock, and it will not hold the load without continuous live air pressure.
