About the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX475-10
The AirTAC SAIJ50X475-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that lets you trim the nominal 475 mm travel back by up to 10 mm, creating a precise 465-475 mm usable window. Built with a SUS304 stainless steel rod and tapered PT ports, it delivers a solid 982 N push force at 0.5 MPa, making it a robust choice for mid-range actuation. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
Because the adjuster acts purely as a mechanical stop on the retract end, it allows you to dial in final end positions during commissioning without adding external stops or swapping the cylinder out. It supports standard variable air cushions at both ends and operates at speeds between 30-800 mm/s. Note that neither the rear stopper nor the cushions will hold a load without live air pressure; for true position holding, consider an external rod lock or the SAIL series.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX475-10 Is Used
Stroke Fine-Tuning
Dial in the exact retract distance within the 465-475 mm window during machine commissioning without installing external physical stops.
Product Changeover
Quickly adjust the end-stop position on automated lines when handling slightly different product sizes or varying material lengths.
Fixture Positioning
Set precise clamping or locating endpoints on manufacturing fixtures where a fixed-stroke cylinder would require manual shimming.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX475-10 the Right Cylinder?
Choose this 50 mm bore when your application requires more thrust than a 40 mm bore (which provides 628 N push at 0.5 MPa) but does not need the bulk of a 63 mm cylinder (1559 N push). The adjustable stroke is ideal for machine setups that require fine end-position tuning during product changeovers rather than relying on a fixed-stroke SAI cylinder. When replacing an ISO 15552 unit, match the 50 mm bore, 475 mm stroke, 10 mm adjustment, PT port thread, and your required mounting from the SAIJ set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Since the stroke is 475 mm, ensure adequate external guiding to prevent side-loading on the piston rod.
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 SAIJ50BX475-10 FAQ
At 0.5 MPa operating pressure, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force. At the maximum 1.0 MPa, it delivers up to 200 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the 475 mm nominal stroke by up to 10 mm, giving a usable travel range of 465 to 475 mm. It only sets the end position and does not lock the load without air pressure.
