Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X75-10
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X75-10 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 75mm 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 JSIJ50X75-10
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore pneumatic actuator brings on-site flexibility to fixed-length installations. Its external adjuster allows you to shorten the extend stroke by up to 10 mm, yielding a usable range of 65-75 mm, while the retract end remains fixed. The hard-anodized aluminum profile barrel keeps the total envelope more compact than a same-bore ISO 15552 unit.
In practical terms it handles a safe working load of roughly 589 N, which equates to lifting about 50 kg vertically with a 2:1 margin. Pneumatically driven through a G1/4 port, the unit relies on adjustable air cushions at both ends to decelerate the load smoothly. Note that this specific SKU lacks a magnet and cannot accept CMSE/DMSE sensors; for the sensing version, an -S variant is required.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X75-10 Is Used
Clamp Stroke Tuning
Dial in the exact 65-75 mm extend reach on a machining fixture to accommodate different part thicknesses without swapping the entire cylinder.
Transfer Gate Adjustment
Fine-tune the diverting arm end position on a packaging line to handle varying carton widths on the fly.
Compact Vertical Lift
Lift approximately 50 kg of stock using the 982 N push force, fitting neatly into tight vertical spaces where ISO 15552 units are too long.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X75-10 the Right Cylinder?
When sizing this actuator, the 50 mm bore sits neatly between the 40 mm option (which provides 628 N push at 0.5 MPa) and the 63 mm option (delivering 1559 N). The 10 mm adjustable window is ideal for sharing a single spare across multiple stroke variants or fine-tuning the end position without remounting the cylinder. Mounting choices include FA, LB, TC, TCM1, and TCM2 brackets. Because this is a non-magnetized model, position sensing is not possible. For any stroke length at or above 300 mm, always use a guide rail to prevent side-load damage to the piston rod.
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 JSIJ50X75-10 FAQ
This 50 mm bore cylinder uses a G1/4 port and generates 982 N push and 825 N pull at 0.5 MPa. At 0.7 MPa, the forces increase to 1374 N push and 1154 N pull. The theoretical maximum force is 200 kgf at 1.0 MPa.
An external stop screw lets you shorten the extend stroke on-site by up to 10 mm, giving a usable extend range of 65-75 mm from the 75 mm nominal maximum. The retract end is fixed. This mechanism only sets the end position; it does not lock the load, so a pilot-operated check valve is needed for holding.
