About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX160-30S
The AirTAC SAIJ63X160-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 160 mm nominal travel by up to 30 mm. This yields a precise 130-160 mm usable window for fine-tuning end positions during commissioning without swapping hardware. It delivers 1559 N of push force and 1402 N of pull force at 0.5 MPa.
This variant features an SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and includes a magnet for position sensing. It is fully compatible with AirTAC CMSE reed and DMSE solid-state switches mounted into the dual-side sensor grooves. The PT tapered port threads and integrated adjustable air cushions ensure reliable sealing and soft end-of-travel deceleration.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX160-30S Is Used
Product Changeovers
Dial in the 130-160 mm travel window during machine setup to accommodate varying product lengths without replacing the entire cylinder assembly.
Sensor Integration
The integrated magnet works seamlessly with DMSE solid-state sensors to confirm end positions in automated assembly lines.
End-Position Tuning
Use the rear stopper screw to precisely set the retract distance during commissioning, avoiding the cost of custom-machined external stops.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX160-30S the Right Cylinder?
Select this 63 mm bore model when a 50 mm bore falls short of the required 982 N push force at 0.5 MPa, but you want to avoid stepping up to an 80 mm bore that demands more physical space. The adjustable stroke is ideal for product changeovers where the exact end-stop distance varies slightly, eliminating the need to bolt on external stops or buy a fixed-stroke SAI cylinder.
When specifying a replacement, match the 63 mm bore, 160 mm stroke, 30 mm adjustment range, PT G3/8 port, and the -S magnet. The rear adjuster acts purely as a travel stop and does not hold the load without live air; for fail-safe load holding, consider the SAIL or BSAI series. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX160-30S FAQ
At 0.5 MPa, this 63 mm bore cylinder provides 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force increases to 2182 N. The operational speed range is 30-800 mm/s.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 160 mm nominal stroke by up to 30 mm, creating a 130-160 mm usable travel window. It is a travel stop, not a lock, so it will not hold the load without continuous air pressure.
