About the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX175-10
The AirTAC SAIJ50X175-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window between 165 and 175 mm without adding external stops. Delivering 982 N of push force and 825 N of pull force at 0.5 MPa, it fits neatly into the mid-thrust class. The SUS304 stainless steel rod material (option B) provides excellent corrosion resistance for demanding environments.
This model uses a PT tapered port thread and relies on a 20 mm rod with an M16x1.5 thread to handle moderate side loads. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to drop in CMSE reed or DMSE electronic switches if position feedback is needed later. The rear adjuster acts purely as a travel stop to set deceleration endpoints, so it will not hold the load safely without live air pressure.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX175-10 Is Used
Commissioning Tolerance Tuning
Dial in the exact 165-175 mm end position during machine build to absorb mechanical tolerances without machining custom spacers.
Product Changeover Stops
Adjust the retract stopper by a few millimeters to accommodate slight variations in incoming product size on a packaging line.
Mid-Thrust Positioning
Leverage the 982 N push force at 0.5 MPa to push parts into a fixture, using the rear stop to prevent overtravel damage.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX175-10 the Right Cylinder?
Choose this 50 mm bore when your application requires the 982 N thrust at 0.5 MPa, stepping up from a 40 mm bore (628 N push) for heavier payloads, or down from a 63 mm bore (1559 N push) to save space. The 10 mm adjustment range is ideal for minor commissioning tweaks or absorbing mechanical tolerances during machine setup, offering flexibility a fixed-stroke SAI cylinder cannot match. To replace an ISO 15552 cylinder, match the 50 mm bore, 175 mm stroke, 10 mm adjustment, PT G1/4 port, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting. Because the stroke is 175 mm, ensure adequate external guiding if the load is unsupported.
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 SAIJ50 Adjustable Cylinder SAIJ50BX175-10 FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 10 mm, creating a 165-175 mm usable travel window. It functions as a mechanical stop to set the end position and does not lock the load without continuous air pressure.
At 0.5 MPa operating pressure, the SAIJ50X175-10 provides 982 N of push force and 825 N of pull force. It can deliver up to 1374 N of push force at 0.7 MPa.
