About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX40-40S
The AirTAC SAIJ32X40-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a usable travel window of 0-40 mm, allowing you to dial in the exact end position during commissioning without external stops. Built with a SUS304 stainless steel rod, it delivers 402 N of push force at 0.5 MPa and operates at speeds of 30-800 mm/s.
This model includes a magnetic piston for position sensing with CMSE reed or DMSE electronic switches. The extruded aluminum barrel features sensor grooves on both sides for flexible mounting. It uses a PT G1/8 port and supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX40-40S Is Used
Precision Positioning
Dial in the exact 0-40 mm end-stop during machine commissioning to meet strict dimensional tolerances without swapping cylinders.
Product Changeover
Quickly adjust the rear stopper to accommodate varying part sizes on a high-mix assembly line.
Light Clamping
Apply up to 402 N of clamping force at 0.5 MPa while fine-tuning the approach distance to protect delicate workpieces.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX40-40S the Right Cylinder?
Choose this 32 mm bore when you need precise 0-40 mm travel tuning, stepping up from smaller compact cylinders if you require 402 N push force at 0.5 MPa. If your application demands higher thrust, consider the 40 mm bore which offers 628 N. The adjustable rear screw is a travel stop, not a lock; it cannot hold a load without live air. For load-holding without pressure, use an external rod lock or explore SAIL and BSAI variants.
To match this ISO 15552 cylinder for replacement, verify the 32 mm bore, 40 mm nominal stroke, 40 mm adjustment range, PT G1/8 port, and the -S magnet option. The standard mounting interfaces exclude FB, CA, CB, and CR brackets.
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 SAIJ32BX40-40S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
The rear adjuster acts as a mechanical stop that allows you to trim the effective travel within a 0-40 mm window. It only sets the end position and does not lock the load without live air pressure.
