The AirTAC Airtac SCJ32 Standard Cylinder SCJ32X100-40S is a genuine double-acting SINGLE-ROD air cylinder with a rear-cap ADJUSTING SCREW: the stroke end is field-adjustable within a 40 mm range without swapping the cylinder. Ø32mm bore, 100mm nominal stroke, PT1/8 ports and adjustable end cushioning.
The SCJ32X100-40S delivers precise, field-adjustable stroke control in a compact 32mm bore package. With a rear-cap screw offering up to 40mm of stroke-end adjustment, it allows fine-tuning of the piston stop position without replacing the cylinder or adding external hard stops. The 12mm diameter rod and M10x1.25 rod thread provide a robust connection for light automation tasks.
At 0.5 MPa, this double-acting, single-rod cylinder generates 402 N of push force and 345 N on the pull stroke, making it suitable for applications where the extend force is the primary work stroke. The built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors for reliable end-of-stroke detection, simplifying integration into sequenced pneumatic circuits.

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.
| 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.

Related types: SC (single rod, fixed stroke), SCD (double rod), SCT (multi-position). SCJ mounting: Basic, FA, LB, TC, TCM1. Seals: TPU standard / H = Viton / N = NBR. Thread: blank = PT, G = G thread.
Fine-tune the end-of-stroke position during initial machine setup without swapping cylinders, perfect for aligning tooling or setting precise stop points on new equipment.
Adjust the stroke end to precisely control the ejection distance of small components on a conveyor, accommodating different part sizes with a simple screw adjustment.
Take up mechanical play or wear in linkages and tooling over time by extending the effective stroke, maintaining consistent clamping or pressing force without reprogramming.
Choose the SCJ32X100-40S when your application requires a stroke that can be reduced by up to 40mm from the 100mm nominal maximum for commissioning or format changes. If you need more force, stepping up to the 40mm bore provides 628 N of push force at the same pressure. For applications requiring a fixed, non-adjustable stroke, the standard SC series is a more cost-effective choice. This model is a direct dimensional and functional replacement for another AirTAC SCJ32X100-40S with a PT port, basic mount, and magnet.
Adjustable-stroke checklist
At the standard operating pressure of 0.5 MPa, this cylinder provides a push force of 402 N and a pull force of 345 N. The push force is higher because it acts on the full 32mm bore area, while the pull force is reduced by the 12mm rod cross-section.
A rear-cap screw limits the piston's extend stroke by up to 40mm, allowing you to set a precise mechanical stop. It is a direct replacement for another SCJ32X100-40S, but it cannot replace a fixed-stroke SC model without verifying that the longer body length and adjusting screw will fit in your available space.
