About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX850-30S
The AirTAC SAIJ160X850-30-S is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty operations. It delivers a substantial 14074N of push force at 0.7 MPa and features a robust 40mm rod with M36x2 threading. Equipped with a -S magnet, the extruded aluminum barrel integrates seamlessly with AirTAC CMSE reed and DMSE electronic solid-state sensors via dual-side sensor grooves.
This model provides a nominal 850mm stroke paired with a rear mechanical adjuster that allows you to trim the effective travel back by up to 30mm, creating a precise 820-850mm usable window. The rod is constructed from SUS420J2 stainless steel (code A) for enhanced durability, and the unit utilizes PT tapered port threads with a G3/4 connection. Variable air cushions at both ends manage deceleration, though the rear stopper is strictly for end-position tuning, not load holding.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX850-30S Is Used
Heavy Press Tuning
Dial in the exact 820-850mm end-of-stroke position on large forming presses during setup, accommodating different die heights without external stopper blocks.
Large Product Changeover
Adjust the retract position on heavy material handling lines to seamlessly switch between oversized product variants on the fly.
Automated Assembly Setup
Fine-tune the extended reach of 160mm bore actuators during initial commissioning to perfect component seating distances without cylinder removal.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX850-30S the Right Cylinder?
Selecting this 160mm bore cylinder makes sense when your application requires the 10053N push force at 0.5 MPa that a 125mm bore cannot provide, yet falls short of needing the 15708N output of a 200mm bore. The adjustable 820-850mm travel window is ideal for fine-tuning end positions during machine commissioning or product changeovers without physically swapping out the cylinder. Because the stroke is 850mm, the extended 40mm rod is subject to significant side loads; an external guide mechanism is highly recommended to prevent premature seal wear and binding.
For an exact ISO 15552 replacement, match the 160mm bore, 850mm stroke, 30mm adjustment range, PT G3/4 port, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, deliberately omitting FB, CA, CB, and CR brackets. Remember that the rear adjuster functions only as a travel stop and does not hold the load without live air; for true pneumatic locking, consider the SAIL or BSAI 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 SAIJ160AX850-30S FAQ
At a 0.7 MPa operating pressure, this 160mm bore cylinder provides 14074N of push force and 9425N of pull force. At the maximum 1.0 MPa pressure, it achieves up to 2050 kgf of push force.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from the nominal 850mm down to a minimum of 820mm. This allows precise end-position tuning during commissioning without needing to add external stops or change the cylinder.
