Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X175-75
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X175-75 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 175mm 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.

About the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X175-75
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder features a 175 mm nominal stroke with a 75 mm external adjuster window. The hard-anodized aluminum extruded barrel omits tie rods entirely, making the overall body shorter and more compact than a same-bore ISO 15552 unit. It operates on a G1/4 port and carries an M18x1.5 rod thread with 20.5 mm adjustable air cushions at both ends.
The external stop screw lets you shorten the extend stroke on-site by up to 75 mm, yielding a usable extend range of 100 to 175 mm without swapping the cylinder. In practical terms it handles about 589 N of real work, which means lifting roughly 50 kg vertically with a 2:1 safety margin. Note that this SKU lacks a magnet and cannot take a CMSE or DMSE sensor; for the magnetic version you need the -S variant. The retract end remains fixed, and the cushion only decelerates the piston rather than holding the load.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X175-75 Is Used
Adjustable Clamping Press
Dial in the exact 100 to 175 mm extend reach on-site to clamp parts of varying widths without changing tooling.
Variable-Length Diverter
Fine-tune the pusher end position by up to 75 mm to accommodate different package sizes on a sorting line.
Compact Lift Station
Lift roughly 50 kg vertically using the shorter JIS profile body to save valuable machine envelope space.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X175-75 the Right Cylinder?
When sizing this 50 mm bore, stepping down to a 40 mm bore drops the 0.5 MPa push force to 628 N, while stepping up to a 63 mm bore raises it to 1559 N. The 75 mm adjuster is ideal when you need to fine-tune the extend end position on-site or want a single shared spare across slightly different stroke variants. You can mount it using the basic body, FA, LB, TC, TCM1, or TCM2 foot and clevis brackets. Because the stroke is 175 mm, ensure adequate guidance to prevent side-loading damage to the rod seal. This plain version has no magnet, so position sensing is not possible without switching to the -S model.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ 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 Set cushions to minimum, then release gradually.
- check Use correct mounting accessory (LB/FA/FB/CA/CB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X175-75 FAQ
At 0.5 MPa it provides 982 N push and 825 N pull. At 0.7 MPa it provides 1374 N push and 1154 N pull. The theoretical maximum force is 200 kgf at 1.0 MPa. The air port is G1/4.
The 175 mm stroke is the maximum extend length. An external stop screw lets you shorten the extend stroke on-site by up to 75 mm, giving a usable range of 100 to 175 mm. The retract end is fixed, and the cushion only decelerates the piston; it does not hold the load.
