About the Airtac SCJ32 Standard Cylinder SCJ32X500-20S
The SCJ32X500-20S is a 32mm bore double-acting single-rod cylinder with a rear-cap adjusting screw, giving you up to 20 mm of field-adjustable stroke-end control on the nominal 500 mm stroke. This model includes a built-in magnet for direct mounting of CMSG/DMSG/EMSG sensors, making end-of-stroke detection simple without extra brackets. Its 12 mm diameter piston rod delivers 402 N of push force at 0.5 MPa, rising to 724 N at the 0.9 MPa maximum operating pressure.
Designed for commissioning trials, format changeovers, and wear take-up, the adjustable screw lets you dial in the exact stop position without swapping the cylinder. The PT1/8 port and M10x1.25 rod thread keep it compact for light automation tasks. The body length A(SCJ) is 182 mm, and the air cushion absorbs 21 mm of travel at each end to reduce impact noise.
Airtac SCJ32 Standard Cylinder SCJ32X500-20S Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X500-20S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 500 mm |
| Stroke adjustment | Up to 20 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 SCJ32X500-20S Is Used
End-Stop Fine Tuning
The 20 mm adjusting screw lets technicians dial in the exact retract or extend stop position during machine commissioning, compensating for small assembly tolerances without re-machining mounting brackets.
Wear Take-Up on Stops
In repetitive transfer stations where a mechanical stop wears over time, the adjustable stroke can be periodically tweaked to restore the original stopping position, extending the service life of the tooling.
Format Changeovers
When a packaging line switches between product sizes, the stroke end can be quickly adjusted to match the new box or tray dimension, reducing downtime compared to changing the cylinder or adding external hard stops.
Is the Airtac SCJ32 Standard Cylinder SCJ32X500-20S the Right Cylinder?
Choose the SCJ32X500-20S when you need a 500 mm nominal stroke with the ability to shorten the end position by up to 20 mm on the machine. If your force requirement grows, stepping up to the 40 mm bore SCJ40 series provides 628 N of push at 0.5 MPa. For applications where the stroke length is fixed and never needs field adjustment, the standard SC32X500 fixed-stroke cylinder is a simpler alternative. This adjustable-stroke unit is a direct replacement for another AirTAC SCJ32 cylinder with a 500 mm nominal stroke, 20 mm adjust range, PT ports, basic mounting, and the -S magnet option.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-20)
- ✓ 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 SCJ32X500-20S FAQ
The push force is 402 N at 0.5 MPa and 724 N at the maximum operating pressure of 0.9 MPa. The pull force is lower at 345 N at 0.5 MPa because the 12 mm rod reduces the effective piston area on the return stroke.
A screw in the rear cap limits how far the piston can retract, effectively shortening the stroke end by up to 20 mm. You turn the screw to set the desired stop position within that range. It adjusts the mechanical end point, not the air pressure or speed.
