About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X220-100S
The AirTAC SAIJ80X220-100-S is a double-acting ISO 15552 profile cylinder featuring a substantial 100 mm rear stroke adjuster. This built-in stopper creates a highly flexible usable travel window from 120 mm to 220 mm, allowing operators to dial in the exact retract end-position during commissioning without adding external stops. It delivers a robust 4523 N of push force at 0.9 MPa, making it ideal for heavier actuation tasks.
Equipped with a standard carbon steel rod and a -S magnet, this unit supports AirTAC CMSE reed and DMSE electronic solid-state sensors via the dual-sided extruded aluminum barrel grooves. The PT tapered porting is G3/8, and the adjustable rear screw functions purely as a travel stop to fine-tune the end position, not as a locking mechanism to hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X220-100S Is Used
Product Changeover Lines
Leverage the 120-220 mm travel window to rapidly reconfigure end-stops when switching between different product sizes on a shared conveyor system.
Machine Commissioning
Fine-tune the final retract position during setup using the rear adjuster, avoiding the need to machine custom spacer blocks or swap cylinders.
Heavy Material Handling
Utilize the 4523 N push force at 0.9 MPa to move heavier pallets or fixtures while retaining the ability to dial back the stroke by up to 100 mm.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X220-100S the Right Cylinder?
Choose this 80 mm bore when your application requires significant thrust, such as the 4523 N push force at 0.9 MPa, but still needs the flexibility of a variable end-stop for product size changeovers. If your force requirements are lower, stepping down to a 63 mm bore yields 2805 N at 0.9 MPa, whereas stepping up to a 100 mm bore provides 7068 N. The 100 mm adjustment range on this specific SKU is particularly valuable for machinery that processes multiple product sizes on a single line, replacing the need to physically swap out a fixed-stroke SAI cylinder.
For ISO 15552 dimensional interchangeability, match the 80 mm bore, 220 mm stroke, 100 mm adjustment, G3/8 PT ports, and -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, intentionally omitting FB, CA, CB, and CR. Because the nominal stroke is 220 mm, the 25 mm rod and M20x1.5 thread provide good rigidity, but an external guide is recommended to prevent side-loading wear. If you need true load-holding without continuous air pressure, this adjuster will not suffice; look to the SAIL pneumatic lock or BSAI clamp-lock cylinders instead.

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 SAIJ80 Adjustable Cylinder SAIJ80X220-100S FAQ
This 80 mm bore cylinder generates 2513 N of push force and 2268 N of pull force at 0.5 MPa. At the maximum operating pressure of 0.9 MPa, it provides 4523 N of push force.
The nominal stroke is 220 mm, but the rear adjuster allows you to shorten the effective travel by up to 100 mm. This results in a usable adjustable stroke window of 120 mm to 220 mm.
