About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX65-10S
The AirTAC SAIJ100X65-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a robust 3927 N push force at 0.5 MPa and features a 65 mm nominal stroke that can be fine-tuned down by up to 10 mm, giving you a precise 55 to 65 mm usable travel window. This built-in adjustability allows you to dial in the retract end position during commissioning without swapping out the cylinder or adding external stops.
This SKU is built with a SUS304 stainless steel rod for superior corrosion resistance and ships with a magnet for position sensing. It operates at speeds of 30 to 800 mm/s and uses a G1/2 port with PT tapered threading. The extruded aluminum barrel includes sensor grooves on both sides, compatible with AirTAC CMSE reed and DMSE electronic solid-state switches.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX65-10S Is Used
Machine Setup & Changeover
Fine-tune the 55 to 65 mm retract end position on the fly during product changeovers without disassembling the machine or adding external stopper blocks.
Variable End-Stop Positioning
Dial in the exact end-of-stroke location during commissioning to accommodate sensor alignment or varying material thicknesses using the rear adjuster.
High-Force Forming Stops
Leverage the 3927 N push force at 0.5 MPa for heavy pressing or holding tasks where the exact bottoming position needs micro-adjustments up to 10 mm.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX65-10S the Right Cylinder?
Choose this 100 mm bore when you need significantly more thrust than a 63 mm cylinder (which yields 1559 N at 0.5 MPa) but want to avoid the bulk of a 125 mm unit. The adjustable stroke is ideal for machine setups requiring variable end-stops or frequent product-size changeovers. Because the rear adjuster acts purely as a mechanical stop and the air cushion only handles deceleration, neither will hold a load without live air pressure; for fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 65 mm stroke, 10 mm adjustment range, G1/2 port, and the -S magnet requirement. Mounting options for this series include Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting the FB, CA, CB, and CR styles. The 25 mm rod diameter and M20x1.5 rod thread provide excellent rigidity, though even with a robust rod, any application approaching the upper stroke limits requires an external guide to prevent side-loading damage.
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 SAIJ100BX65-10S FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. If you increase the pressure to 0.7 MPa, the push force rises to 5497 N.
The rear adjusting screw acts as a mechanical stop that lets you shorten the 65 mm nominal stroke by up to 10 mm, creating a 55 to 65 mm usable travel window. It sets the end position but does not lock the load without continuous air pressure.
