About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX50-50
The AirTAC SAIJ200X50-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, designed to deliver massive thrust in confined travel ranges. With a 200mm bore operating at 0.5 MPa, it generates 15708N of push force and 15080N of pull force. The integrated -50 adjustment code means you can dial back the nominal 50mm stroke, providing a 0-50mm usable travel window to perfectly tune the retract end-position during commissioning without adding external stops.
This model features a SUS304 stainless steel rod (option B) for superior corrosion resistance and a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic solid-state switches, though this specific SKU is supplied without a piston magnet. It carries the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting the FB, CA, CB, and CR options.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX50-50 Is Used
Press Fit Tuning
Dial in the exact 0-50mm retract position during press assembly commissioning to accommodate varying part heights without swapping cylinders.
Component Insertion
Adjust the end-stop on the fly for product changeovers, ensuring precise insertion depths for different housing variants on the same line.
Short-Stroke Clamping
Leverage the 15708N push force for heavy-duty clamping tasks, using the rear screw to set the exact clamping clearance for varying workpiece sizes.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX50-50 the Right Cylinder?
Choose this 200mm bore adjustable cylinder when your application requires extreme force within a short, variable travel distance. If you need less thrust, stepping down to a 160mm bore yields 10053N of push force at 0.5 MPa, which may suffice for lighter duties. The SAIJ200X50-50 is selected over a fixed-stroke SAI when a process requires fine end-position tuning at machine setup or product changeover, utilizing the 0-50mm adjustment window to adapt the retract stop on the fly.
Remember that the rear adjuster functions strictly as a travel stop to set deceleration and end-position; it does not hold the load without live air pressure. For applications requiring true load-holding without continuous pneumatic pressure, consider an external pilot-operated check valve or AirTAC SAIL and BSAI locking cylinders. Operating speed for this 200mm bore is rated at 30-500 mm/s. Because the 50mm stroke is well below the 300mm threshold, side-load stress on the 40mm rod and M36x2 thread is minimized, though external guides are always recommended for heavy loads.

- ✓ 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 SAIJ200BX50-50 FAQ
At 0.5 MPa, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At 1.0 MPa, it reaches a maximum push force of 21991N. The operating speed range is 30-500 mm/s.
The rear adjuster acts as a mechanical stop that lets you trim the effective stroke back by up to 50mm from the nominal 50mm length, creating a 0-50mm usable travel window. It sets the end-position and deceleration but does not lock the load without live air pressure.
