The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X100-100S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 100mm stroke, G1/4 air ports and adjustable end cushioning. Its no-tie-rod, hard-anodized profile barrel is more compact than an ISO 15552 cylinder of the same bore — a space-saver on tight machines.
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder is built for applications needing exact end-position tuning on the floor. Its external adjuster lets you shorten the extend stroke by up to 100 mm from the nominal maximum, while the retract end stays fixed. The extruded hard-anodized aluminium barrel makes the body shorter and more compact than a same-bore ISO 15552 unit.
The integrated -S piston magnet accepts CMSE/DMSE switches in the side grooves for precise position feedback. With a G1/4 port and an M18x1.5 rod thread, it handles a safe working load of roughly 589 N, which equates to lifting about 50 kg vertically with a 2:1 margin. Adjustable 20.5 mm air cushions at both ends absorb impact, though a plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve for held loads.

Dial in the exact 0-100 mm extend contact distance for a light-duty pressing or staking operation without reprogramming the machine cycle.
Set the precise pusher extension on a packaging line to deflect different carton sizes on the fly using the external stop screw.
Use the 50 kg vertical lift capacity to act as a height-adjustable pallet stop, tuning the extend length on-site for various pallet heights.
When sizing this 50 mm bore, step down to a 40 mm cylinder for lighter duties (628 N push at 0.5 MPa) or move up to a 63 mm bore if you need 1559 N. The 100 mm adjuster window is ideal when you need to share one spare across several stroke variants or fine-tune the extend end without swapping the whole actuator. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. The -S suffix means the magnet is already fitted for CMSE/DMSE sensors. For any stroke length at or above 300 mm, always use a guide rail to prevent side-load damage.
Quick checklist
At 0.5 MPa it provides 982 N push and 825 N pull. At 0.7 MPa it delivers 1374 N push and 1154 N pull. The theoretical maximum is 200 kgf at 1.0 MPa. The air port is G1/4.
The nominal 100 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke on-site by up to 100 mm, giving a usable extend range of 0-100 mm. The retract end is fixed, and the stop screw sets the end position rather than locking the load.
