About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX160-50
The AirTAC SAIJ200X160-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 160 mm travel by up to 50 mm for a precise 110-160 mm usable window. It delivers immense thrust, generating 15708 N of push force and 15080 N of pull force at 0.5 MPa, making it ideal for heavy-duty pressing and clamping.
This unit features a SUS420J2 stainless steel rod for superior corrosion resistance and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU lacks the internal magnet, meaning CMSE or DMSE electronic switches cannot be used without a model change.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX160-50 Is Used
Heavy Pressing Operations
Ideal for high-tonnage pressing where the 110-160 mm travel window can be fine-tuned to accommodate different material thicknesses without changing tooling.
Product Changeover
Enables rapid line changeovers by allowing operators to shorten the stroke by up to 50 mm directly at the rear stopper, adapting to new product sizes instantly.
Industrial Clamping
Provides rigid clamping for large components, utilizing the 3204 kgf maximum force while allowing precise adjustment of the clamping depth.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX160-50 the Right Cylinder?
Select this 200 mm bore actuator when an application requires massive output force—up to 21991 N at 0.7 MPa—that smaller bores cannot provide. The adjustable end-stop is perfect for machine setups requiring precise end-position tuning during commissioning or product changeovers, eliminating the need to swap out a fixed-stroke SAI cylinder. For any stroke at or above 300 mm, an external guide is recommended to prevent excessive rod side-loading, though this 160 mm unit is well within standard limits.
When specifying a replacement, ensure you match the 200 mm bore, 160 mm stroke, 50 mm adjustment range, PT port thread, and the absence of a magnet. Remember that the rear adjuster acts strictly as a travel stop and does not hold the load without live air; for true load-holding, consider an AirTAC SAIL or BSAI cylinder. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ200AX160-50 FAQ
At an operating pressure of 0.5 MPa, this 200 mm bore cylinder provides a push force of 15708 N and a pull force of 15080 N. At 0.7 MPa, the push force increases to 21991 N.
The rear adjuster acts as a mechanical stop that allows you to shorten the effective stroke from its nominal 160 mm down to 110 mm. It is a travel stop for fine-tuning end positions, not a lock, and cannot hold a load without continuous air pressure.
