About the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX130-20
The AirTAC SAIJ40X130-20 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 130 mm nominal stroke that can be fine-tuned down by up to 20 mm, giving you a usable travel window of 110-130 mm. Delivering 628 N of push force at 0.5 MPa, it fits mid-range automation tasks perfectly.
This unit is built with a SUS304 stainless steel rod for superior corrosion resistance and ships with PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to add CMSE or DMSE switches later if positioning feedback becomes necessary.

Where the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX130-20 Is Used
Machine Commissioning
Dial in the exact 110-130 mm end-stop during initial setup to perfect part ejection without machining custom spacers.
Product Changeover
Quickly trim the stroke by up to 20 mm on the rear adjuster when switching the line to a slightly different package size.
Corrosive Environments
Leverage the SUS304 stainless steel rod for reliable mid-force clamping in washdown or mildly corrosive manufacturing areas.
Is the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX130-20 the Right Cylinder?
Choose this 40 mm bore when a 32 mm bore (402 N push at 0.5 MPa) lacks thrust, but a 63 mm bore (1559 N) is physically oversized. The 20 mm rear adjuster is ideal for dialing in the exact end-stop during machine commissioning or product changeovers without swapping hardware. Remember that the rear screw acts as a travel stop, not a lock; the SAIJ cannot hold a load without live air, so consider a SAIL or BSAI cylinder if dead-load holding is required.
To match this ISO 15552 dimensionally interchangeable cylinder, specify a 40 mm bore, 130 mm stroke, 20 mm adjustment, PT port thread, and the SUS304 (B) rod material. Since the 130 mm stroke is under the 300 mm threshold, external side-load guides are less critical, but the 16 mm rod still handles standard lateral loads effectively.
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 SAIJ40 Adjustable Cylinder SAIJ40BX130-20 FAQ
At 0.5 MPa operating pressure, this 40 mm bore cylinder provides 628 N of push force and 528 N of pull force. If you need more thrust, stepping up to a 50 mm bore yields 982 N of push force at the same pressure.
The rear adjuster screw lets you shorten the 130 mm nominal stroke by up to 20 mm, creating a 110-130 mm travel window. It acts as a mechanical stop to fine-tune the retract position and does not lock the load without continuous air pressure.
