About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX150-50
The AirTAC SAIJ32X150-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to dial back the 150 mm nominal stroke by up to 50 mm. This creates a flexible 100-150 mm usable travel window, enabling precise end-position tuning at commissioning without swapping the cylinder or adding external stops. It delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
Equipped with a SUS304 stainless steel rod (option B) and PT tapered port threads, this 32 mm bore unit is built for demanding environments. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic sensors. The rear adjuster acts purely as a travel stop for deceleration and positioning; it does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX150-50 Is Used
Product Changeover Tuning
Quickly adjust the 100-150 mm travel window during product size changeovers on a packaging line, fine-tuning the end position without swapping hardware.
Variable End-Stop Positioning
Dial in the exact retract distance for a machining operation, using the rear stopper to set precise material engagement without external mechanical stops.
Commissioning Stroke Calibration
Perfect for initial machine setup where the exact stroke requirement is unknown, allowing operators to trim the 150 mm travel back by up to 50 mm on the fly.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX150-50 the Right Cylinder?
Choose this SAIJ32X150-50 when your machine setup requires a variable end-stop within a 100-150 mm travel window, whereas a fixed SAI cylinder locks you into one exact dimension. If your application requires higher thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. Since this unit lacks a magnet (-S), it cannot host internal sensors; add the -S suffix if you need CMSE or DMSE detection.
For an ISO 15552 replacement, match the 32 mm bore, 150 mm stroke, 50 mm adjustment, PT port threads, SUS304 (B) rod, and your required mounting from the reduced SAIJ set: Basic, FA, LB, TC, FTC, TCM1, or TCM2. Because the 150 mm stroke is relatively short, the 12 mm rod handles normal loads well, but always use an external guide for heavy lateral forces. Remember that the air cushion and rear stopper do not function as a lock; for load-holding without live pressure, consider the SAIL or BSAI series.
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 SAIJ32BX150-50 FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It operates at speeds ranging from 30 to 800 mm/s.
The rear adjuster screw lets you shorten the 150 mm nominal stroke by up to 50 mm, creating a usable travel window of 100 to 150 mm. This stopper only sets the end position and does not lock the load without continuous air pressure.
