About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX115-100S
The AirTAC SAIJ32X115-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the nominal 115 mm stroke back by up to 100 mm. This yields a highly versatile 15-115 mm usable travel window, perfect for dialing in exact end positions during machine setup or product changeovers without swapping hardware.
This specific SKU is built with a SUS420J2 stainless steel rod (material code A) for improved corrosion resistance and includes a piston magnet (-S) for position sensing. The extruded aluminum barrel integrates sensor grooves on both sides, accepting AirTAC CMSE reed switches or DMSE solid-state sensors. It uses PT tapered port threads (G1/8), runs at speeds from 30-800 mm/s, and relies on variable air cushions at both ends to decelerate the load.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX115-100S Is Used
Machine Commissioning
Dial in the exact 15-115 mm end position during initial setup without machining new hard stops or changing the cylinder.
Product Changeover
Quickly adapt the travel window on packaging lines when switching between different package sizes or formats.
Variable End Stops
Use the 100 mm adjustment range to test multiple stroke lengths on a test rig before finalizing a fixed-stroke SAI design.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX115-100S the Right Cylinder?
The massive 100 mm adjustment range on a 115 mm base stroke allows you to shorten the travel down to 15 mm for testing or changeovers, avoiding the need to bolt on external stops.
As an ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders, matching bore, stroke, and PT port dimensions. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Remember that the rear adjuster and air cushions only set the travel end and decelerate the load; they do not hold the load without live air. For true load-holding without pressure, consider the SAIL (air-released lock) or BSAI (clamp-lock) series. The 12 mm rod and M10x1.25 thread handle moderate side loads, but long unsupported strokes still require an external guide.
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 Adjustable Cylinder SAIJ32 SAIJ32AX115-100S FAQ
It features a rear external adjusting screw that acts as a stopper on the retract end. You can shorten the nominal 115 mm stroke by up to 100 mm, creating a usable travel window of 15-115 mm. The adjuster sets the end position but does not lock the load without live air pressure.
The standard speed range for the 32 mm bore is 30-800 mm/s, controlled by variable air cushions at both ends.
