About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX800-50
The AirTAC SAIJ160X800-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 750-800 mm usable travel window. Delivering 18095 N of pull force at 0.9 MPa, it handles heavy-duty positioning. The SUS304 stainless steel rod and PT tapered port threads ensure high corrosion resistance and tight sealing.
Because the rear adjuster acts purely as a travel stop, it cannot hold a load without live air pressure. For dead-load holding, an external pilot-operated check valve or an AirTAC BSAI clamp-lock cylinder is required. The extruded aluminum barrel includes sensor grooves on both sides, ready for DMSE solid-state or CMSE reed switches if a magnet is added later.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX800-50 Is Used
Heavy Press Tuning
Dial in the exact 750-800 mm end position for large assembly presses during initial commissioning without machining external stop blocks.
Product Size Changeover
Quickly adapt a long-stroke diverter on a packaging line to accommodate new oversized carton formats using the 50 mm rear adjustment range.
Automated Welding Positioning
Move heavy weldments into fixtures with high force, relying on the SUS304 rod to withstand harsh industrial environments and weld spatter.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX800-50 the Right Cylinder?
Choose this 160 mm bore when stepping up from a 125 mm cylinder, which provides 11045 N of push force at 0.9 MPa, to gain the 18095 N needed for heavier tooling. The 50 mm adjustment range is ideal for fine-tuning end positions during machine setup or product-size changeovers without adding external stops. To replace this ISO 15552 cylinder, match the 160 mm bore, 800 mm stroke, 50 mm adjustment, PT ports, SUS304 rod, and Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting.
At 800 mm of travel, the 40 mm rod diameter and M36x2 thread provide rigidity, but an external guide rail is strongly recommended to prevent side-load damage on long unsupported strokes.
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 SAIJ160BX800-50 FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder generates 18095 N of pull force and 14074 N of push force at 0.7 MPa.
The rear adjuster screw lets you mechanically shorten the 800 mm nominal stroke by up to 50 mm, providing a usable travel window of 750-800 mm. It acts only as a travel stop and does not lock the load without live air pressure.
