About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X190-100S
The AirTAC SAIJ160X190-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers substantial thrust, providing 14074N of push force and 9425N of pull force at 0.7 MPa. The built-in magnet enables position sensing with AirTAC CMSE reed or DMSE electronic switches. Featuring a carbon steel rod and PT tapered port threads, this unit is designed for heavy-duty applications requiring exact end-position tuning.
This model features a 190 mm nominal stroke that can be dialed back by up to 100 mm, creating a highly flexible 90-190 mm usable travel window. The rear adjuster acts as a mechanical stop to fine-tune the retract position during commissioning or product changeovers without swapping the cylinder. It is an extruded aluminum profile cylinder with sensor grooves on both sides, and it utilizes variable air cushions at both ends to decelerate the heavy 40 mm rod smoothly.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X190-100S Is Used
Variable Product Forming
Dial in the exact 90-190 mm retract stop for heavy-duty forming presses that handle multiple material thicknesses, ensuring precise depth control without mechanical changeovers.
Heavy Clamp Positioning
Secure large workpieces on automated machining lines by fine-tuning the clamping endpoint at commissioning, leveraging the 14074N push force at 0.7 MPa.
Machine Setup Optimization
Adjust the rear stopper screw during product changeovers to instantly modify the stroke window, eliminating the downtime needed to physically swap out cylinders.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X190-100S the Right Cylinder?
Choose this 160 mm bore when an application demands high force, such as 14074N push at 0.7 MPa. If your setup requires less thrust, stepping down to a 125 mm bore yields 8590N push at 0.7 MPa, whereas moving up to a 200 mm bore provides 21991N. The adjustable 90-190 mm travel window is ideal for machines processing variable product sizes, allowing operators to set the end-stop precisely on the fly instead of adding external stops or reverting to a fixed-stroke SAI cylinder.
For a correct ISO 15552 replacement match, verify the 160 mm bore, 190 mm stroke, 100 mm adjustment range, PT port threads, and the -S magnet option. Mounting choices are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR. Because the 190 mm stroke is under the 300 mm side-load threshold, the robust 40 mm rod handles standard loads well, but always ensure proper guiding for heavy lateral forces. Note that the rear adjuster is a travel stop, not a lock; the SAIJ will not hold a load without live air, so consider an AirTAC SAIL or BSAI cylinder if true load-holding is required.

- ✓ 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 SAIJ160 Adjustable Cylinder SAIJ160X190-100S FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder generates a push force of 14074N and a pull force of 9425N. At 0.5 MPa, the push force is 10053N and the pull force is 9425N.
The rear adjuster acts as a mechanical stop that allows you to shorten the 190 mm nominal stroke by up to 100 mm, providing an effective travel window of 90-190 mm. It sets the retract end position but does not lock the load without continuous air pressure.
