About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX800-50
The AirTAC SAIJ100X800-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that creates a 750-800 mm usable travel window from its 800 mm nominal stroke. Delivering 7068 N of push force at 0.9 MPa, it integrates a 25 mm piston rod and M20x1.5 rod thread to handle substantial side loads. This specific configuration incorporates a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads for a robust pneumatic connection.
Because the rear adjuster acts strictly as a mechanical stop to fine-tune the retract end position during commissioning, it does not lock the load without live air pressure. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to easily mount CMSE reed or DMSE electronic solid-state switches if a magnet is specified later. It supports a standard speed range of 30-800 mm/s and features adjustable air cushions at both ends to manage deceleration.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX800-50 Is Used
Multi-Size Forming Press
Dial in the exact 750 to 800 mm retract stop for different part lengths during production changeovers without repositioning the physical cylinder mount.
Adjustable Transfer Pusher
Accommodates varying package depths on a sorting line by fine-tuning the rear stroke stopper up to 50 mm, ensuring precise placement before downstream handling.
Long-Stroke Assembly Ram
Provides 7068 N of thrust at 0.9 MPa for heavy clamping duties while allowing operators to trim the forward travel window to match varying fixture heights.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX800-50 the Right Cylinder?
Choose this 100 mm bore when an 80 mm bore (providing 4523 N push force at 0.9 MPa) is insufficient for your tooling weight, but a 125 mm bore (offering 11045 N) would be excessive overkill. The adjustable 50 mm end-stop is ideal for product changeovers on a line, letting you dial in the exact retract distance without swapping cylinders or fabricating external spacers. For any load-holding requirements during an air loss event, this cylinder cannot hold its position; you must integrate an external rod lock or select the SAIL or BSAI series instead.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 800 mm stroke, PT ports, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the stroke is 800 mm, an external guide is highly recommended to prevent rod binding and premature seal wear from side-loading forces.
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 SAIJ100BX800-50 FAQ
At a 0.9 MPa operating pressure, this 100 mm bore cylinder provides 7068 N of push force and 5497 N of pull force. It can deliver a maximum thrust of 801 kgf at 1.0 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from 800 mm down to 750 mm. It only sets the end position and deceleration; it does not hold the load without live air pressure.
