The AirTAC Airtac SCJ32 Standard Cylinder SCJ32X300-100 is a genuine double-acting SINGLE-ROD air cylinder with a rear-cap ADJUSTING SCREW: the stroke end is field-adjustable within a 100 mm range without swapping the cylinder. Ø32mm bore, 300mm nominal stroke, PT1/8 ports and adjustable end cushioning.
The SCJ32X300-100 is a double-acting, single-rod pneumatic cylinder that puts stroke-end fine-tuning directly in your hands via a rear-cap adjusting screw. With a 100 mm adjustment range, you can dial in the exact stroke length on the machine without swapping cylinders or adding external hard stops, making it ideal for commissioning trials and format changeovers. The 12 mm diameter piston rod and 21 mm air cushion deliver reliable deceleration across the 300 mm nominal stroke.
At 0.5 MPa, this bore 32 cylinder generates 402 N of push force and 345 N on the pull stroke, stepping up to 724 N at the 0.9 MPa maximum operating pressure. The PT1/8 port and M10x1.25 rod thread keep it compact for light automation tasks. Body length A measures 182 mm, and the standard stroke ceiling for this bore is 1000 mm, so the 300 mm stroke is well within standard production limits.

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.
The 100 mm rear-screw adjustment lets technicians fine-tune the stroke end during initial machine bring-up, eliminating the need to stock multiple fixed-stroke cylinders for trial-and-error positioning.
On packaging or sorting lines, quickly adjust the cylinder stroke to accommodate different product sizes without mechanical rework, reducing downtime between batches.
As tooling or gripper pads wear over time, the adjustable stroke can be extended slightly to maintain precise contact, extending the service life of the end-of-arm tooling.
Choose the SCJ32X300-100 when you need to fine-tune the stroke end position across a 100 mm window during setup or production changes. If the 402 N push force at 0.5 MPa is slightly low, the SCJ40 series offers 628 N at the same pressure; if the 300 mm stroke is more than you need, a shorter standard stroke like 200 mm reduces the envelope. For fixed-stroke applications where adjustment is never required, the standard SC32X300 is a simpler, cost-effective alternative.
For a drop-in replacement, match the SCJ32 bore, 300 mm nominal stroke, 100 mm adjust range, PT1/8 ports, and basic mounting style. At 300 mm, the rod is fully supported by the front bushing, but if the load applies significant side force, consider an external guide rail or a guided cylinder to protect the rod bearing from premature wear.
Adjustable-stroke checklist
At the standard 0.5 MPa operating pressure, it delivers 402 N pushing force and 345 N pulling force. At the maximum 0.9 MPa, the push force increases to 724 N. The pull force is always lower because the rod reduces the effective piston area on the return stroke.
Yes, provided the port thread (PT1/8), mounting style, and 300 mm nominal stroke match. The SCJ adds a rear adjusting screw that shortens the stroke by up to 100 mm, so ensure you have clearance behind the cylinder for the screw mechanism. The body is slightly longer than the fixed-stroke SC equivalent.
