About the Airtac SCJ32 Standard Cylinder SCJ32X500-10
The SCJ32X500-10 is a double-acting, single-rod pneumatic cylinder that adds a rear-cap adjusting screw to the proven SC platform. With a 32 mm bore and a 12 mm rod, it delivers 402 N of push force at 0.5 MPa, rising to 724 N at the maximum operating pressure of 0.9 MPa. The -10 suffix means the screw can shorten the effective stroke end by up to 10 mm, letting you dial in the exact stop position during commissioning or after wear without replacing the cylinder.
This model has a 500 mm nominal stroke, which is the maximum standard stroke for the 32 mm bore. The body length A(SCJ) is 182 mm plus the stroke, making it a compact solution for end-stop tuning. It uses a PT1/8 port, an M10x1.25 rod thread, and a 21 mm air cushion to decelerate the piston smoothly. The default seal is TPU for a -20 to +70 °C working range.
Airtac SCJ32 Standard Cylinder SCJ32X500-10 Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X500-10 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 500 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 SCJ32X500-10 Is Used
Commissioning Fine-Tuning
During machine setup, use the 10 mm rear screw to micro-adjust the retract stop position for perfect alignment with fixtures or sensors, eliminating the need for shims or custom end-stops.
Wear Compensation on Stops
On a packaging line, a mechanical stop can wear over thousands of cycles. The adjustable stroke lets an operator quickly take up 1-10 mm of play, maintaining precise placement without downtime for a cylinder swap.
Format Changeover
When a light-duty assembly cell switches between product sizes, the SCJ32X500-10 allows a technician to adjust the stroke end in seconds to match the new component length, rather than changing the actuator.
Is the Airtac SCJ32 Standard Cylinder SCJ32X500-10 the Right Cylinder?
Choose the SCJ32X500-10 when you need to fine-tune a 500 mm stroke end by up to 10 mm on the machine. If you require more push force, step up to the 40 mm bore, which provides 628 N at 0.5 MPa. For applications that do not need field adjustment, the fixed-stroke SC32X500 is a simpler alternative. A direct replacement must match the 32 mm bore, 500 mm nominal stroke, -10 adjust range, PT port thread, and basic mounting.
At a 500 mm stroke, the 12 mm rod is slender. Evaluate any side-loading carefully; 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.
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 SCJ32X500-10 FAQ
The adjusting screw only sets the stroke end position; it does not alter the cylinder's force. At 0.5 MPa, this single-rod cylinder provides 402 N pushing and 345 N pulling. The maximum push force at 0.9 MPa is 724 N.
Yes, if you need the adjustable stroke feature. The SCJ32X500-10 has the same 32 mm bore, 500 mm nominal stroke, and PT1/8 port, but its body is slightly longer to house the rear adjusting screw. Ensure your mounting space can accommodate the SCJ's body length A of 182 mm plus stroke.
