About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX350-20
The AirTAC SAIJ160X350-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 350 mm stroke that can be dialed back by up to 20 mm, creating a precise 330-350 mm usable travel window for commissioning without adding external stops. Equipped with a SUS304 stainless steel rod and PT tapered ports, it delivers a robust 14074 N pull force at 0.7 MPa. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This model uses variable air cushions at both ends to decelerate the heavy 18095 N maximum load. The rear adjuster acts strictly as a travel stop and does not hold the load without live air pressure; for true load-holding, consider the SAIL or BSAI series. It supports a speed range of 30-500 mm/s and utilizes a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX350-20 Is Used
Variable End-Stop Tuning
Dial in the exact 330-350 mm retraction point during machine commissioning to accommodate varying product lengths without swapping the cylinder.
Product Changeover
Quickly adjust the effective stroke on the line when switching to a new product size, minimizing downtime and avoiding external stop hardware.
Heavy-Duty Positioning
Leverage the 14074 N pull force to move heavy assemblies into place, using the rear screw to set the precise final resting position.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX350-20 the Right Cylinder?
Choose this 160 mm bore when you need to step up from the 125 mm class (which offers 8590 N pull at 0.7 MPa) to handle significantly higher forces. The adjustable stroke is ideal for product changeovers or fine-tuning the end position during machine setup, offering flexibility a fixed SAI cylinder cannot match. When ordering a replacement, verify the 160 mm bore, 350 mm stroke, 20 mm adjustment, PT ports, SUS304 (B) rod material, and the required mounting bracket. Since the 350 mm stroke is long, an external guide is recommended to prevent excessive side-loading on the rod.
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 SAIJ160BX350-20 FAQ
The rear adjuster screw lets you shorten the 350 mm nominal stroke by up to 20 mm, providing a 330-350 mm travel window. It acts as a mechanical stop to fine-tune the end position during setup.
At 0.7 MPa, it provides 14074 N of pull force and 14074 N of push force. At 0.9 MPa, the pull force reaches 18095 N.
