About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX100-30S
The AirTAC SAIJ200X100-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that lets you dial back the nominal 100 mm travel by up to 30 mm, creating a precise 70-100 mm usable window. It delivers massive thrust, pushing 28274 N at 0.9 MPa and pulling 15080 N at 0.5 MPa, making it ideal for heavy-duty press operations. The stainless steel SUS304 rod provides excellent corrosion resistance, while the integrated magnet (-S) enables direct mounting of CMSE reed or DMSE electronic sensors along the dual-side barrel grooves.
This model uses a PT tapered port and omits the FB, CA, CB, and CR mounting styles, utilizing a specific subset of ISO 15552 attachments (Basic, FA, LB, TC, FTC, TCM1, TCM2). The rear stopper screw acts purely as a travel end-position tuner for product changeovers; it does not lock or hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX100-30S Is Used
Heavy-Duty Press Tuning
Dial in the exact 70-100 mm end-position during heavy press commissioning without swapping out the entire cylinder or adding external mechanical stops.
Product Line Changeover
Quickly adjust the retract stopper to accommodate varying product sizes on a high-force assembly line, ensuring precise positioning across batches.
Robotic End Effectors
Leverage the SUS304 stainless steel rod and 28274 N push force for robust, corrosion-resistant actuation in heavy material handling grippers.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX100-30S the Right Cylinder?
Select this 200 mm bore cylinder when your application demands up to 3204 kgf of maximum thrust and requires variable end-stops for frequent machine setup changes. If you do not need on-the-fly stroke tuning, the standard fixed-stroke SAI cylinder is a simpler alternative. To match this SKU exactly, specify the 200 mm bore, 100 mm nominal stroke, 30 mm adjustment range, PT port thread, SUS304 rod material, and the -S magnet option.
Because the 100 mm stroke is relatively short for this large bore, side-load risks are minimal, but the substantial 40 mm rod diameter and M36x2 thread handle high mechanical stress well. Remember that the adjuster and air cushions only decelerate the travel end; they do not function as a brake. If you need to step down to a smaller force class, the 160 mm bore offers 18095 N of push force at 0.9 MPa.
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 SAIJ200BX100-30S FAQ
At an operating pressure of 0.9 MPa, this 200 mm bore cylinder delivers a push force of 28274 N and a pull force of 15080 N. At 0.5 MPa, it provides 15708 N of push force.
The rear adjuster screw allows you to shorten the 100 mm nominal stroke by up to 30 mm, providing a usable travel window of 70 to 100 mm. This stopper only sets the end position; it does not hold the load without live air pressure.
