About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX220-50S
The AirTAC SAIJ160X220-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits up to 50 mm of travel reduction. This yields a usable stroke window of 170 to 220 mm, allowing precise end-position tuning at commissioning without external stops. Driven by a G3/4 PT port, it delivers substantial thrust, pushing 14074 N and pulling 9425 N at 0.7 MPa. The 40 mm SUS304 stainless steel rod (code B) provides high corrosion resistance and handles demanding side loads better than smaller rods.
This adjustable-stroke variant uses an extruded aluminum barrel with sensor grooves on both sides. Equipped with a magnet (-S), it supports AirTAC CMSE reed and DMSE electronic solid-state sensors for exact position feedback. It includes variable air cushions at both ends (50 mm cushion length) to decelerate heavy masses, operating at speeds of 30-500 mm/s. The mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX220-50S Is Used
Heavy Press Tuning
Dial in the exact 170-220 mm travel window during machine setup to accommodate varying material thicknesses without swapping out the entire actuator.
Product Changeover
Rapidly adjust the retract end-stop on a packaging line when switching to a new product size, relying on the 40 mm stainless rod for robust actuation.
Fixture Positioning
Fine-tune the clamping distance on large fixtures using the rear stopper, while DMSE electronic sensors confirm the adjusted end position.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX220-50S the Right Cylinder?
Select this 160 mm bore when an application requires high force (up to 18095 N push at 0.9 MPa) alongside flexible end-stop positioning. If your changeover demands less force, stepping down to a 125 mm bore yields 11045 N push at 0.9 MPa, whereas moving up to a 200 mm bore provides 28274 N. Choose the SAIJ adjustable type over a fixed SAI cylinder when you need to fine-tune the retract distance on the fly during product size changes. For any stroke at or above 300 mm, an external guide is recommended to prevent excessive side-loading on the rod.
To match this ISO 15552 interchangeable cylinder, confirm a 160 mm bore, 220 mm nominal stroke, 50 mm adjustment range, G3/4 PT ports, SUS304 rod material, and a magnet for CMSE/DMSE sensors. Note that the rear adjuster acts only as a mechanical stop and the air cushion provides deceleration; neither holds the load without live air pressure. For true load-holding without continuous air, consider the SAIL (air-released lock) or BSAI (clamp-lock) cylinders, or use an external pilot-operated check valve.
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 SAIJ160 Adjustable Cylinder SAIJ160BX220-50S FAQ
The rear adjuster acts as a mechanical stopper that lets you shorten the effective stroke by up to 50 mm. This creates a usable travel window of 170 to 220 mm, allowing precise end-position tuning at commissioning without replacing the cylinder.
At 0.7 MPa, it provides 14074 N of push force and 9425 N of pull force. At the maximum operating pressure of 1.0 MPa, the push force reaches 18095 N.
