About the Airtac SCJ32 Standard Cylinder SCJ32X450-10
The SCJ32X450-10 is a double-acting, single-rod pneumatic cylinder that puts stroke-end fine-tuning at your fingertips. With a 32 mm bore and a 12 mm piston rod, it delivers 402 N of push force at 0.5 MPa, while the rear adjusting screw lets you shorten the stroke end by up to 10 mm without dismounting the cylinder or adding external hard stops.
This model uses a PT1/8 port and an M10x1.25 rod thread, with a21 mm air cushion at each end for smooth deceleration. The tie-rod body length (A dimension) is 182 mm, making it compact enough for inline placement where a fixed-stroke cylinder would require shimming during commissioning.
Airtac SCJ32 Standard Cylinder SCJ32X450-10 Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X450-10 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 450 mm |
| Stroke adjustment | Up to 10 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 SCJ32X450-10 Is Used
Commissioning & Setup
Dial in the exact stroke end position during machine bring-up without swapping cylinders. The 10 mm adjuster lets technicians fine-tune the stop point for a pick-and-place or clamp in seconds.
Wear Take-Up
Compensate for gripper jaw wear or belt stretch over time. A quick turn of the rear screw restores the correct end position, extending service intervals on packaging or assembly lines.
Format Changeovers
Switch between product sizes on a single machine by adjusting the stroke end. The SCJ32X450-10 allows operators to set a new stop for a different box height or part thickness without mechanical rework.
Is the Airtac SCJ32 Standard Cylinder SCJ32X450-10 the Right Cylinder?
Choose the SCJ32X450-10 when your machine needs a repeatable but field-tunable end position, such as dialing in a gripper close point or a dispense height. If you need more force, step up to the 40 mm bore SCJ40 series, which provides 628 N push at 0.5 MPa. For applications where the stroke is permanently fixed and never needs adjustment, the standard SC32X450 is a simpler, lower-cost alternative.
At 450 mm of stroke, be mindful of side loading on the 12 mm rod. If the load is not guided externally, consider adding a guide rail or switching to a guided cylinder to prevent rod bending and premature seal wear. A direct replacement must match the 32 mm bore, 450 mm nominal stroke, 10 mm adjust range, PT1/8 ports, and basic mounting.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-10)
- ✓ 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 SCJ32X450-10 FAQ
At 0.5 MPa, the cylinder generates 402 N of push force and 345 N of pull force. The push force is higher because the single rod reduces the piston area on the return side. Maximum push force at the 0.9 MPa operating limit is 724 N.
Yes, this is a direct form-and-function replacement for any AirTAC SCJ32 cylinder with a 450 mm nominal stroke and a 10 mm adjustable range. Ensure the port thread (PT1/8), mounting style (basic), and magnet option (none) match your original to guarantee identical performance and fit.
