Airtac SAIJ160 Adjustable Cylinder SAIJ160BX950-75S
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160BX950-75S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 950mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX950-75S
The AirTAC SAIJ160X950-75-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that dials back the effective travel to a 875-950mm window. Equipped with a 40mm SUS304 stainless steel rod and PT tapered ports, it delivers a robust 14074N of push force at 0.7 MPa. The extruded aluminum barrel includes dual sensor grooves, and because this unit carries the -S magnet option, it directly supports AirTAC CMSE reed and DMSE solid-state electronic switches for precise end-of-travel detection.
This adjustable-stroke design eliminates the need to physically swap cylinders or bolt on external stops when fine-tuning end positions during machine commissioning. It is important to note the rear adjuster acts purely as a mechanical travel stop to set deceleration alongside the air cushions, not as a locking device. The cylinder will not hold a load without live air pressure, so load-holding applications require an external rod lock or a SAIL/BSAI series cylinder.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX950-75S Is Used
Large Press Tonnage
Provides 14074N of thrust at 0.7 MPa for heavy pressing operations, with the 875-950mm travel window allowing exact positioning of large tooling.
Bulk Material Diversion
Handles heavy pallets or product flows on a conveyor line, using the rear stopper to fine-tune the diverting stroke length during product size changeovers.
Automated Assembly Jigs
Drives large assembly fixtures where the 950mm stroke reaches across wide machine beds, while the SUS304 rod resists corrosion in humid plant environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX950-75S the Right Cylinder?
Choose this 160mm bore when you need substantially higher thrust than the 100mm bore offers, which provides 5497N of push force at 0.7 MPa. The 950mm stroke on this model is substantial, and because long unsupported travels are highly susceptible to side-loading, an external guide rail is strongly recommended to prevent premature wear to the 40mm rod and seals. Operating speed is 30-500 mm/s, supported by 50mm adjustable air cushions at both ends.
When replacing an ISO 15552 cylinder, match the 160mm bore, 950mm stroke, 75mm adjustment, PT G3/4 port, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets. If your application requires the piston to mechanically hold its position without continuous air pressure, step up to a SAIL air-released lock or BSAI clamp-lock cylinder instead of relying on the SAIJ adjuster.
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 SAIJ160BX950-75S FAQ
At 0.7 MPa operating pressure, this 160mm bore cylinder generates 14074N of push force and 9425N of pull force, with a maximum rated thrust of 2050 kgf at 1.0 MPa.
The rear adjuster screw lets you shorten the nominal 950mm stroke by up to 75mm, providing a usable travel window of 875-950mm. This stopper fine-tunes the end position during setup but does not lock the load without live air pressure.
