About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX105-100
The AirTAC SAIJ200X105-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust up to 15708 N at 0.5 MPa. It features a robust 40 mm SUS304 stainless steel rod and a PT tapered G3/4 port. By integrating an external adjusting stopper, this cylinder allows you to fine-tune the retracted end position during commissioning without swapping out the entire unit.
With a 105 mm nominal stroke and a 100 mm adjustment code, this SKU provides a highly versatile usable travel window of 5 to 105 mm. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Remember that the rear adjuster functions strictly as a travel stop for deceleration and positioning, not as a lock; it cannot hold a load without continuous live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX105-100 Is Used
Heavy Press Tuning
Dial in the exact 5-105 mm travel window during heavy press commissioning to accommodate varying material thicknesses without changing the cylinder.
Product Size Changeover
Quickly adjust the retracted end-stop on a packaging line when switching between different large-format product sizes, minimizing machine downtime.
Large Fixture Alignment
Fine-tune the clamping position of heavy industrial fixtures by turning the rear adjuster, ensuring precise alignment of 200 mm bore thrust forces.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX105-100 the Right Cylinder?
Choose this 200 mm bore cylinder when an application demands extreme force, such as 15708 N push or 15080 N pull at 0.5 MPa, alongside precise end-position tuning. If your setup requires less thrust, stepping down to a 160 mm bore yields 10053 N of push force, which might better suit medium-duty tasks. The adjustable stroke is ideal for product-size changeovers on a line, allowing operators to dial in the exact 5-105 mm travel window without adding external stops.
Because this model features a 105 mm stroke, the long unsupported piston rod requires an external guide to prevent excessive side-loading and premature seal wear. For replacing an ISO 15552 cylinder, match the 200 mm bore, 105 mm stroke, PT port, and mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Note that SAIJ omits FB, CA, CB, and CR mounts. If the machine requires true load-holding without pneumatic pressure, select a SAIL air-released lock or BSAI clamp-lock cylinder instead of relying on the 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 SAIJ200 Adjustable Cylinder SAIJ200BX105-100 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. It can reach a maximum push force of 28274 N at 1.0 MPa.
The rear adjuster acts as a stopper that lets you trim the effective stroke back by up to 100 mm. This creates a usable travel window of 5 to 105 mm from the 105 mm nominal stroke, allowing you to set the exact end position at commissioning.
