The AirTAC Airtac SCJ32 Standard Cylinder SCJ32X175-30S is a genuine double-acting SINGLE-ROD air cylinder with a rear-cap ADJUSTING SCREW: the stroke end is field-adjustable within a 30 mm range without swapping the cylinder. Ø32mm bore, 175mm nominal stroke, PT1/8 ports and adjustable end cushioning.
The SCJ32X175-30S is a double-acting, single-rod pneumatic cylinder with a 32 mm bore and a nominal 175 mm stroke, equipped with a rear-cap adjusting screw that provides a 30 mm field-adjustable range for fine-tuning the stroke end position. This model includes a built-in magnet (-S), enabling direct mounting of CMSG/DMSG/EMSG sensors for precise, non-contact position feedback. With a 12 mm diameter piston rod and PT1/8 ports, it delivers 402 N of push force at 0.5 MPa, scaling up to 724 N at the maximum operating pressure of 0.9 MPa.
Designed for dynamic applications requiring flexible commissioning and changeover, the tie-rod construction and adjustable air cushion ensure reliable deceleration. The body length A for this SCJ series is 182 mm, providing a compact envelope for the 32 mm bore class. This genuine AirTAC unit is a direct replacement for any SCJ32X175-30S cylinder, matching bore, nominal stroke, 30 mm adjust range, PT thread, and the integrated magnet for sensor-ready operation.

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 30 mm adjustment screw allows technicians to dial in the perfect end-stop position during initial machine setup without swapping cylinders or fabricating external hard stops.
In clamping or pressing fixtures, the adjustable stroke can be extended over time to compensate for tooling or pad wear, maintaining consistent contact force without mechanical shimming.
Quickly adapt the cylinder's stroke for different product sizes on a packaging or assembly line by adjusting the rear screw, minimizing downtime between production runs.
Choose the SCJ32X175-30S when your application demands a 175 mm maximum stroke with the ability to shorten the end position by up to 30 mm without replacing the cylinder, a common need during machine commissioning or format changes. If the 402 N push force at 0.5 MPa is insufficient, stepping up to the 40 mm bore SCJ series provides 628 N of push force, while a step down is not available below the 32 mm bore. For applications with a fixed, unchanging stroke, the standard SC32X175-S offers the same force and mounting without the adjusting mechanism.
This cylinder is a direct form-and-function replacement for an existing AirTAC SCJ32X175-30S, matching the 32 mm bore, 175 mm nominal stroke, 30 mm adjustment, PT port, basic mounting, and the -S magnet. The 175 mm stroke is well within the 1000 mm maximum standard stroke for this bore, ensuring standard availability. For strokes of this length, always ensure the load is guided to prevent excessive side-loading and premature rod bearing wear.
Adjustable-stroke checklist
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 due to the single 12 mm rod, providing 345 N at 0.5 MPa.
A rear-cap screw mechanically limits the piston's stroke end within a 30 mm range, shortening the nominal 175 mm stroke. This SCJ32X175-30S is a direct drop-in replacement for any AirTAC cylinder with the same 32 mm bore, 175 mm nominal stroke, 30 mm adjust range, PT port, and -S magnet option.
