About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX250-10
The AirTAC SAIJ32X250-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to dial back the nominal 250 mm stroke by up to 10 mm, creating a precise 240-250 mm usable travel window for end-position tuning. It delivers 402 N of push force and 345 N of pull force at 0.5 MPa, fitting compact automation tasks.
This variant uses a SUS304 stainless steel rod for corrosion resistance and features PT tapered ports. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2. The rear screw acts as a travel stop to set deceleration, but it will not hold a load without live air pressure; for true load-holding, consider the SAIL or BSAI series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX250-10 Is Used
End-Position Tuning
Fine-tune the 240-250 mm travel window at commissioning without swapping cylinders, ensuring precise contact on varying product heights.
Machine Changeovers
Quickly adjust the rear stopper during product size changes on a packaging line, saving setup time and avoiding external stop hardware.
Lightweight Positioning
Leverage the 402 N push force and SUS304 rod for precise, corrosion-resistant component placement in compact assembly machinery.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX250-10 the Right Cylinder?
Choose this 32 mm bore when a 402 N push force at 0.5 MPa is sufficient, stepping up to the 40 mm bore (628 N) only if your payload demands more clamping power. An adjustable stroke is ideal for machine setups requiring variable end-stops during product changeovers, eliminating the need to physically swap cylinders or bolt on external stops.
Because this is a 250 mm stroke unit, the 12 mm rod and M10x1.25 thread handle moderate side loads, but long unsupported strokes still require an external guide. To match this ISO 15552 cylinder, specify the 32 mm bore, 250 mm stroke, 10 mm adjustment, PT ports, SUS304 rod material, and no magnet.
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 SAIJ32BX250-10 FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers up to 82 kgf.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective travel from the nominal 250 mm down to 240 mm. It sets the travel end and deceleration point but does not lock or hold the load without live air pressure.
