Airtac SAIJ200 Adjustable Cylinder SAIJ200BX375-10S
The AirTAC Airtac SAIJ200 Adjustable Cylinder SAIJ200BX375-10S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 375mm 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 SAIJ200BX375-10S
The AirTAC SAIJ200X375-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a substantial 15708 N push force at 0.5 MPa and features a SUS304 stainless steel rod alongside PT tapered ports. The integrated -S magnet supports AirTAC CMSE reed and DMSE electronic sensors, fitting cleanly into the extruded aluminum barrel grooves on both sides.
With a nominal 375 mm stroke and a 10 mm adjustment range, this model yields a usable travel window of 365 to 375 mm. This built-in mechanical stop allows you to fine-tune the retract end position at commissioning without adding external stops or swapping the cylinder. The rear adjuster and the variable air cushions only set the travel end and decelerate the load; neither holds the load without live air pressure. For load-holding without continuous air, an external pilot-operated check valve or a related AirTAC BSAI clamp-lock cylinder is required.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX375-10S Is Used
Heavy Press Fine-Tuning
Dial in the exact 365-375 mm retract position during initial commissioning of a large metal forming press without machining external stopper blocks.
Product Size Changeover
Quickly adapt the end-stop on an automated assembly line when switching between product variants of slightly different heights.
Large Clamp Positioning
Secure and position heavy industrial components, using the 10 mm travel window to set the precise clamping depth on the machine tooling.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX375-10S the Right Cylinder?
Choose this 200 mm bore cylinder when an application demands up to 15708 N of push force at 0.5 MPa, or 21991 N at 0.7 MPa. If your force requirements are lower, stepping down to a 160 mm bore yields 10053 N at 0.5 MPa, while moving up is unnecessary unless you exceed 3204 kgf at 1.0 MPa. The adjustable stroke is ideal for machine setups requiring variable end-stops during product changeovers, offering flexibility that a fixed-stroke SAI cylinder cannot match.
When replacing an ISO 15552 cylinder, match the 200 mm bore, 375 mm stroke, 10 mm adjustment, PT port thread, and the -S magnet requirement. SAIJ uses a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Because the stroke is 375 mm, the 40 mm diameter SUS304 rod and M36x2 thread can carry significant side loads, but long unsupported strokes still require an external guide to prevent rod binding.

- ✓ 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 SAIJ200BX375-10S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N.
The rear adjuster acts as a mechanical stop, allowing you to shorten the 375 mm nominal stroke by up to 10 mm, creating a usable travel window of 365 to 375 mm. It only sets the end position and does not lock the load without live air pressure.
