About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X130-20
The AirTAC SAIJ160X130-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down to a 110-130 mm usable window. Equipped with a robust 40 mm carbon steel rod and a G3/4 PT port, it delivers substantial thrust, pushing 14074 N at 0.7 MPa and pulling 9425 N at the same pressure. This makes it highly suitable for heavy-duty operations requiring precise end-position calibration.
Because the adjuster acts as a retract-end stop rather than a locking mechanism, it relies on the integrated variable air cushion to decelerate the load while still requiring live air to hold position. The extruded aluminum barrel includes sensor grooves on both sides, and while this unit lacks a magnet, adding one enables use with CMSE reed or DMSE electronic switches for end-of-travel signaling.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X130-20 Is Used
Heavy Press Calibration
Dial in the exact 110-130 mm travel window during initial commissioning to ensure heavy pressing operations strike accurately without mechanical shims.
Product Line Changeover
Quickly adapt the retract end-position by up to 20 mm when switching between product sizes on a high-force assembly line, minimizing downtime.
Large Fixture Positioning
Securely move heavy industrial fixtures into place, relying on the 18095 N push force at 0.9 MPa to shift massive loads smoothly.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X130-20 the Right Cylinder?
Choose this 160 mm bore when your application demands high force that smaller bores cannot provide; stepping down to a 125 mm bore reduces your 0.5 MPa push force to 6136 N, whereas this model provides 10053 N. The 20 mm adjustment range is ideal for machine setup and product changeover, allowing you to dial in the exact end-stop without swapping out the entire cylinder or adding external stops. For any load-holding requirements without live air pressure, this cylinder is insufficient as the adjuster is only a stop, so you should explore an SAIL pneumatic lock, a BSAI clamp-lock, or an external pilot-operated check valve.
When specifying a replacement, ensure you match the 160 mm bore, 130 mm stroke, 20 mm adjustment, G3/4 PT port, and the reduced SAIJ mounting set which includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options. Although this 130 mm stroke is relatively short for this bore size, the heavy 40 mm rod handles greater side loads, yet any application with long unsupported travel still necessitates an external guide to prevent premature wear.

- ✓ 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 SAIJ160X130-20 FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder provides a push force of 14074 N and a pull force of 9425 N. At the maximum pressure of 1.0 MPa, it can deliver up to 2050 kgf of thrust.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 130 mm nominal stroke by up to 20 mm, creating a 110-130 mm usable travel window. It allows for fine-tuning the end position at commissioning without external stops, but it does not lock the load without live air pressure.
