About the Airtac SCJ32 Standard Cylinder SCJ32X80-100
The SCJ32X80-100 brings field-adjustable stroke to compact pneumatic tasks, letting you dial the stroke end back by up to 100 mm without swapping the cylinder. With a 12 mm rod and PT1/8 ports, it delivers 402 N of push force at 0.5 MPa, ideal for light clamping, sorting, or feeding mechanisms where space is tight.
The rear adjusting screw shortens the nominal 80 mm stroke end, making commissioning and format changes fast. Its 21 mm air cushion at each end decelerates the piston quietly, and the 182 mm body length keeps the assembly compact for tight machine envelopes.
Airtac SCJ32 Standard Cylinder SCJ32X80-100 Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X80-100 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 80 mm |
| Stroke adjustment | Up to 100 mm (rear adjusting screw) |
| Acting type | Double acting (single rod) |
| Port size | PT1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Adjustable, 21 mm |
| Max stroke | Up to 1000 mm |
Specifications follow the official AirTAC SCJ (adjustable-stroke) datasheet. The rear adjusting screw sets the stroke end position; force is the same as the equivalent single-rod SC bore. Confirm against the product label before installation. Thread options: PT (standard) / G.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
SCJ is single-rod, so force matches the equivalent SC bore: push uses the full bore area, pull subtracts the rod area. Actual usable force is lower than theoretical due to friction and back-pressure; size with a safety margin.

Where the Airtac SCJ32 Standard Cylinder SCJ32X80-100 Is Used
Commissioning Fine-Tuning
Dial in the exact end-stop position during machine setup without machining hard stops or swapping cylinders, speeding up line start.
Part Feeding
Adjust the push stroke on a feeder to accommodate slight variations in part length or position without reprogramming the controller.
Wear Compensation
Take up mechanical play in linkages or tooling over time by advancing the stroke end screw, maintaining consistent contact pressure.
Is the Airtac SCJ32 Standard Cylinder SCJ32X80-100 the Right Cylinder?
Choose the SCJ32X80-100 when you need to dial in a precise stroke end on a 32 mm bore platform. If you need more push force, step up to the SCJ40 series, which provides 628 N at 0.5 MPa. For fixed-stroke applications, the standard SC32 is a simpler alternative. To replace this unit, match the 32 mm bore, 80 mm nominal stroke, 100 mm adjust range, PT1/8 thread, and basic mounting. The adjustable stroke eliminates the need for external hard stops in many setups.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-100)
- ✓ Required force at your working pressure
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Set the rear adjusting screw, then lock it before running.
- check Adjust end cushion screws for smooth stops.
- check Use SCJ mounting accessory (FA / LB / TC / TCM1).
- check Installation by qualified personnel per AirTAC docs.
Airtac SCJ32 Standard Cylinder SCJ32X80-100 FAQ
A rear-cap screw limits the piston's retract stroke end. You can shorten the effective stroke by up to 100 mm from the nominal 80 mm, adjusting it in the field without disassembling the cylinder.
Yes, if you need adjustable stroke. It matches the 32 mm bore, PT1/8 ports, and basic mount. Ensure the 100 mm adjust range covers your stroke reduction needs and that the slightly longer body fits your space.
