Airtac SAIJ200 Adjustable Cylinder SAIJ200BX140-30
The AirTAC Airtac SAIJ200 Adjustable Cylinder SAIJ200BX140-30 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 140mm stroke, G3/4 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 SAIJ200 Adjustable Cylinder SAIJ200BX140-30
The AirTAC SAIJ200X140-30 is a double-acting ISO 15552 profile cylinder featuring a rear mechanical stopper that allows you to trim the effective stroke. With a 140mm nominal stroke and a 30mm adjustment range, you get a usable travel window of 110-140mm to perfectly dial in end positions during commissioning. It delivers serious force, pushing with 15708N and pulling with 15080N at 0.5 MPa.
This heavy-duty unit uses a robust 40mm SUS304 stainless steel rod with an M36x2 thread, handling high side-loads far better than smaller bores. It features PT tapered ports sized at G3/4 and uses a reduced mounting subset (Basic, FA, LB, TC, FTC, TCM1, TCM2) that omits FB, CA, CB, and CR brackets. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX140-30 Is Used
Heavy Press Tuning
Dial in the exact 110-140mm travel window during setup to accommodate varying material thicknesses on a high-force press line without swapping cylinders.
Product Changeover
Quickly adjust the retract end-stop on a conveyor diverter when switching between different package sizes on the fly.
Assembly Station Setup
Fine-tune the end position at commissioning to achieve precise alignment for heavy component mating, using the rear screw rather than adding external stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX140-30 the Right Cylinder?
Choose this 200mm bore when you need maximum thrust up to 15708N at 0.5 MPa; stepping down to a 160mm bore drops your push force to 10053N. The adjustable 110-140mm window is ideal for machine changeovers where you need a variable end-stop without machining external spacers or buying a fixed-stroke SAI cylinder. If your process requires true load-holding on retraction without continuous air pressure, skip this standard adjuster and look at the SAIL or BSAI locking cylinders instead.
When ordering, confirm the 200mm bore, 140mm stroke, 30mm adjustment, PT G3/4 port, and the SUS304 rod material. Because the 40mm rod is thick, side-load resilience is high, but for any stroke over 300mm you should still add an external guide rail to prevent binding.
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 SAIJ200 Adjustable Cylinder SAIJ200BX140-30 FAQ
At 0.5 MPa, this 200mm bore cylinder provides a push force of 15708N and a pull force of 15080N. At the maximum operating pressure of 1.0 MPa, it delivers up to 3204 kgf.
The rear adjuster screw lets you shorten the 140mm nominal stroke by up to 30mm, creating a usable travel window of 110-140mm. The adjuster is a mechanical stop that sets the end position, but it does not lock or hold the load without live air pressure.
