About the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX260-50
The AirTAC SAIJ50X260-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 260 mm travel by up to 50 mm for a usable window of 210-260 mm. It delivers 982 N of push force at 0.5 MPa, making it a solid mid-range choice for precise positioning tasks.
This SKU features a SUS420J2 stainless steel rod (option A) for improved corrosion resistance and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed or DMSE electronic switches if a magnet is added later. It supports a speed range of 30-800 mm/s and uses the standard SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, TCM2.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX260-50 Is Used
Product Changeovers
Quickly adjust the end-of-stroke position by up to 50 mm when switching between product sizes on a packaging line, avoiding mechanical rebuilds.
Machine Setup
Fine-tune the 210-260 mm travel window during commissioning to perfectly time the 982 N push force against varying mechanical stops.
Variable End Stops
Dial in the exact retraction point for sorting or diverting tasks on a conveyor without adding external hard stops to the frame.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX260-50 the Right Cylinder?
Choose this 50 mm bore when you need more thrust than the 40 mm version (628 N push at 0.5 MPa) but want a smaller footprint than the 63 mm option (1559 N). The 50 mm adjustment range is perfect for machines handling frequent product size changeovers, letting you set exact end positions at commissioning without swapping hardware.
Because the 260 mm stroke exceeds 300 mm is not the case here, but always ensure external guides support side loads on longer strokes. Remember that the rear adjuster is a travel stop, not a lock; the cylinder will not hold a load without live air. For load-holding without pressure, consider the SAIL or BSAI series. To replace an ISO 15552 cylinder, match the 50 mm bore, 260 mm stroke, 50 mm adjust, PT G1/4 port, and mounting style.
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 SAIJ50AX260-50 FAQ
At 0.5 MPa operating pressure, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force. It can reach up to 1767 N push force at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective travel from the 260 mm nominal stroke down to as little as 210 mm. It sets the end position but does not lock the load without continuous air pressure.
