About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX50-20
The AirTAC SAIJ160X50-20 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 14074 N push force at 0.7 MPa, utilizing a sizable 40 mm piston rod and a G3/4 port to efficiently move heavy loads. The rear adjustment screw allows you to fine-tune the end-of-travel position, providing a usable stroke window between 30 and 50 mm without adding external stops.
Built with a SUS304 stainless steel rod (option B) and PT tapered port threads, this unit is tailored for demanding environments. The extruded aluminum barrel features sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic sensors. It utilizes the standard SAIJ mounting set, including Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR mounts.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX50-20 Is Used
Machine Changeovers
Dial in the 30-50 mm travel window during product size transitions to set precise end positions without swapping the entire cylinder or adding external spacers.
Heavy Clamping Stops
Leverage the 14074 N push force at 0.7 MPa to secure heavy workpieces, using the rear stopper to fine-tune the exact clamping depth at commissioning.
Assembly Pressing
Press bearings or pins with a 40 mm rod that handles high side loads, adjusting the effective stroke on the fly to accommodate different assembly heights.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX50-20 the Right Cylinder?
Choose this 160 mm bore when you need higher thrust than the 125 mm bore, which provides 8590 N push at 0.5 MPa. The adjustable 30-50 mm travel window is ideal for product-size changeovers on a packaging line, letting you dial in the exact end position at commissioning rather than machining custom spacers. Because the rear adjuster acts only as a travel stop and the air cushions handle deceleration, this cylinder cannot hold a load without live air pressure; for true load-holding, consider the SAIL or BSAI series. To match an ISO 15552 replacement, verify the 50 mm stroke, 20 mm adjustment range, G3/4 PT port, and your required mounting interface.
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 SAIJ160BX50-20 FAQ
At 0.7 MPa, the 160 mm bore generates a push force of 14074 N and a pull force of 9425 N. It can reach a maximum push force of 18095 N at 0.9 MPa.
The rear adjuster screw lets you shorten the 50 mm nominal stroke by up to 20 mm, creating a usable travel window of 30 to 50 mm. The adjuster functions as a mechanical stop and does not lock the load without live air pressure.
