About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX170-20S
The AirTAC SAIJ100X170-20-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers a robust 3927N push force at 0.5 MPa and features a built-in magnet for position sensing. The -20 adjustment code allows you to dial back the 170mm nominal stroke, creating a precise 150-170mm usable travel window for exact end-position tuning without adding external stops.
Equipped with a SUS420J2 stainless steel rod and PT tapered port threads, this model handles demanding environments. The extruded aluminum barrel includes sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic switches. It uses the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX170-20S Is Used
Machine Setup & Changeover
Fine-tune the 150-170mm travel window during product size changes on a packaging line, avoiding physical cylinder swaps.
Variable End-Stop Positioning
Dial in the exact retract distance for assembling components with varying heights, using the rear screw for precise end-position tuning.
Heavy-Duty Clamping
Leverage the 3927N push force to secure heavy workpieces, relying on the adjuster to set the perfect clamping depth without external stops.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX170-20S the Right Cylinder?
Choose this 100mm bore cylinder when an 80mm bore (2513N push at 0.5 MPa) lacks thrust, but you still need the exact 150-170mm adjustable travel window. The rear adjuster acts purely as a travel stop to fine-tune the end position during machine commissioning or product changeover. It does not hold the load without live air; for true load-holding without pressure, select an SAIL (air-released lock) or BSAI (clamp-lock) cylinder instead.
When replacing an ISO 15552 cylinder, match the 100mm bore, 170mm stroke, 20mm adjustment, PT ports, and the -S magnet requirement. Because the stroke is under 300mm, side-load risks are moderate, but the 25mm rod and M20x1.5 thread handle standard stresses well. For long unsupported strokes, always use an external guide to prevent binding.
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 SAIJ100AX170-20S FAQ
At 0.5 MPa, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. At 0.7 MPa, the push force increases to 5497N.
The rear adjuster screw lets you shorten the 170mm nominal stroke by up to 20mm, creating a 150-170mm usable travel window. It functions as a travel stop for end-position tuning and is not a locking mechanism.
