About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX190-30
The AirTAC SAIJ100X190-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 190 mm travel by up to 30 mm. This creates a 160-190 mm usable positioning window for fine-tuning the retract end at commissioning without swapping hardware. It delivers substantial thrust, offering 3927 N of push force and 3681 N of pull force at 0.5 MPa.
This SKU features a SUS304 stainless steel rod (material code B) for superior corrosion resistance and includes a PT (tapered) G1/2 port. The extruded aluminum barrel includes sensor grooves on both sides, though this specific configuration omits the magnet option. The rear adjuster acts purely as a mechanical stop to set the travel end and does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX190-30 Is Used
Machine Setup & Changeover
Dial in the exact 160-190 mm retract position during commissioning or product size changes without replacing the entire cylinder.
Variable End-Stop Tuning
Use the rear screw to fine-tune the end-of-stroke position, absorbing mechanical tolerance variations across a multi-station assembly.
Heavy Payload Handling
Leverage the 3927 N push force at 0.5 MPa to shift heavy jigs or parts, relying on the stainless rod for durable, corrosion-resistant operation.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX190-30 the Right Cylinder?
Select this 100 mm bore when an 80 mm cylinder (providing 2513 N push at 0.5 MPa) is insufficient for heavy handling, but a 125 mm bore is oversized. The 30 mm adjustment range is ideal for product changeovers requiring slightly different retract positions, replacing the need to bolt on external stops or swap a fixed-stroke SAI cylinder. Because the stroke is under 300 mm, side-load stress on the M20x1.5 rod thread is moderate, but an external guide remains recommended for heavy lateral loads.
To match this cylinder for an ISO 15552 replacement, specify a 100 mm bore, 190 mm stroke, 30 mm adjustment, PT G1/2 port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and no magnet. If your application requires the load to be held mechanically without live air, use an SAIL pneumatic lock cylinder or a BSAI clamp-lock instead of relying on this rear adjuster.
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 SAIJ100 Adjustable Cylinder SAIJ100BX190-30 FAQ
At 0.5 MPa, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At the maximum operating pressure of 1.0 MPa, it can deliver up to 801 kgf.
The rear adjuster screw lets you shorten the nominal 190 mm stroke by up to 30 mm, creating a usable travel window of 160-190 mm. The adjuster acts as a mechanical stop to set the end position and does not function as a lock to hold the load without air pressure.
