Airtac SAIJ160 Adjustable Cylinder SAIJ160X100-20S
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160X100-20S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 100mm stroke, G3/4 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 SAIJ160 Adjustable Cylinder SAIJ160X100-20S
The AirTAC SAIJ160X100-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling you to dial back the 100 mm nominal stroke by up to 20 mm. This yields a precise 80-100 mm usable travel window, perfect for fine-tuning end positions during commissioning without swapping out the actuator. It features a carbon steel rod and a built-in magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors.
Belonging to the 160 mm bore class, this heavy-duty actuator generates 14074 N of push force and 9425 N of pull force at 0.7 MPa. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. While the rear adjuster screw and variable air cushions manage end-of-stroke deceleration, neither will hold a load without live air pressure; for true load-holding, an external rod lock or SAIL cylinder is required.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X100-20S Is Used
Heavy Press Fine-Tuning
Dial in the exact 80-100 mm travel window during machine setup to accommodate varying material thicknesses without re-engineering the press frame.
Automated Line Changeover
Quickly adjust the retract end-position by up to 20 mm when switching the production line to a new product size, saving hours of mechanical retooling.
High-Force Positioning
Leverage the 14074 N push force at 0.7 MPa to move heavy pallets or molds, using the rear stopper to set precise end-of-travel limits for each cycle.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X100-20S the Right Cylinder?
Choose this 160 mm bore when your application requires substantial thrust—stepping down to a 125 mm bore drops the 0.7 MPa push force to 8590 N, while moving up to a 200 mm bore increases it to 21991 N. The adjustable stroke is ideal for machinery that requires variable end-stops or frequent product-size changeovers, eliminating the need to bolt on external stopper blocks compared to a fixed-stroke SAI cylinder. To ensure a true ISO 15552 replacement match, verify the 100 mm stroke, 20 mm adjustment range, PT tapered port threads, and the -S magnet option.
Because the nominal stroke is 100 mm, side-load risks are minimal, but the 40 mm rod diameter and M36x2 thread provide excellent rigidity if guiding is slightly misaligned. Note that the SAIJ mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR mounts found on some other series.
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 SAIJ160 Adjustable Cylinder SAIJ160X100-20S FAQ
At a standard 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074 N of push force and 9425 N of pull force. It can achieve a maximum push force of 18095 N at 0.9 MPa.
The rear adjuster screw allows you to shorten the 100 mm nominal stroke by up to 20 mm, creating an adjustable 80-100 mm travel window. This stopper only sets the end position; it does not lock the load without continuous air pressure.
