Airtac Adjustable Cylinder SAIJ32 SAIJ32X70-10
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32X70-10 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 70mm stroke, G1/8 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 Adjustable Cylinder SAIJ32 SAIJ32X70-10
The AirTAC SAIJ32X70-10 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 402N push force at 0.5 MPa and features a 12mm carbon steel rod with an M10x1.25 thread. By integrating an external adjusting screw, this cylinder allows you to trim the nominal 70mm stroke back by up to 10mm, creating a precise 60-70mm usable travel window for exact positioning.
This fine-tuning capability is executed directly at the rear stopper during commissioning, eliminating the need to swap out the entire cylinder or bolt on external stops when product sizes change. The extruded aluminum barrel includes sensor grooves on both sides, and while this unit lacks a magnet, adding an -S designation enables compatibility with AirTAC CMSE reed and DMSE electronic solid-state switches for position feedback.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X70-10 Is Used
End-Position Tuning
Dial in the exact 60-70mm travel window during machine commissioning to perfect the final clamping or pressing position without physical shims.
Product Changeover
Quickly adjust the rear stopper by up to 10mm to accommodate slight variations in product sizes on a high-mix assembly line.
Light-Force Positioning
Utilize the 402N thrust for delicate sorting or pushing tasks where a fixed 70mm stroke might over-travel and damage components.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X70-10 the Right Cylinder?
Choose this 32mm bore when an application demands 402N of push force at 0.5 MPa but requires exact end-position tuning that a fixed-stroke SAI cannot provide. If your setup needs less force, stepping down is not an option in this frame, but stepping up to a 40mm bore yields 628N of push force. The SAIJ32X70-10 uses a PT tapered port thread and supports a mounting set limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR configurations.
Because the rear adjuster acts strictly as a travel stop and the air cushions manage deceleration, neither component will hold a load securely without live air pressure. For applications requiring true load-holding in the event of air loss, consider the SAIL pneumatic lock or BSAI clamp-lock cylinders instead. Operating speed for this bore ranges from 30-800mm/s.
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 Adjustable Cylinder SAIJ32 SAIJ32X70-10 FAQ
The rear adjuster screw allows you to shorten the effective travel by up to 10mm. This creates a usable stroke window of 60-70mm, letting you fine-tune the retract end position during setup without changing the cylinder.
At 0.5 MPa, this 32mm bore cylinder provides 402N of push force and 345N of pull force. It can reach a maximum push force of 724N at 0.9 MPa.
