About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX55-50S
The AirTAC SAIJ32X55-50-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 5 to 55 mm, allowing you to dial back the 55 mm nominal stroke by up to 50 mm during commissioning.
This variant includes a SUS304 stainless steel rod for corrosion resistance and a built-in magnet for position sensing. The extruded aluminum barrel carries sensor grooves on both sides, directly supporting AirTAC CMSE reed and DMSE electronic solid-state switches. It features PT tapered port threads (G1/8) and uses the standard SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ32BX55-50S Is Used
Machine Setup Tuning
Dial in the exact end-position during commissioning, trimming the stroke from 55 mm down to 5 mm to perfect a delicate assembly motion.
Product Changeover Stops
Quickly adjust the travel end-stop on a packaging line to handle different carton sizes without changing out the cylinder.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX55-50S the Right Cylinder?
Choose this 32 mm bore when an application requires precise end-position tuning without swapping hardware. The massive 50 mm adjustment range on this 55 mm stroke lets you set variable end-stops for product changeovers, functioning as a hard travel stop rather than a lock.
For direct replacements, match the 32 mm bore, 55 mm stroke, 50 mm adjustment range, PT G1/8 ports, and the -S magnet. Remember that the rear adjuster and air cushions only decelerate the travel end; they do not hold the load without live air. For true load-holding without pressure, use an external pilot-operated check valve or select a SAIL or BSAI cylinder.
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 SAIJ32BX55-50S FAQ
A rear stopper screw lets you mechanically shorten the effective stroke by up to 50 mm. This creates a usable travel window of 5 to 55 mm, allowing fine-tuning of the end position without adding external stops.
