The AirTAC Airtac SCJ32 Standard Cylinder SCJ32X500-100S 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, 500mm nominal stroke, PT1/8 ports and adjustable end cushioning.
The SCJ32X500-100S is a double-acting, single-rod pneumatic cylinder with a 100 mm field-adjustable stroke range, letting you fine-tune the end position without swapping the unit. Its 32 mm bore delivers 402 N of push force at 0.5 MPa and up to 724 N at 0.9 MPa, making it suitable for light-duty positioning and clamping tasks.
This model includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise end-of-stroke detection. The 12 mm diameter piston rod and M10x1.25 rod thread provide solid mechanical connection, while the 21 mm air cushion at each end ensures smooth deceleration across the full 500 mm nominal stroke.

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 adjustment screw allows technicians to quickly dial in the exact stroke end position during machine commissioning, eliminating the need for custom-length cylinders or hard stops.
On packaging lines, the adjustable stroke lets operators reset the pusher or diverter stroke length in minutes when switching between different product sizes, reducing downtime.
In clamping fixtures, the stroke can be incrementally extended over time to compensate for pad or tooling wear, maintaining consistent clamping force without replacing the actuator.
Choose the SCJ32 when you need a compact, adjustable-stroke actuator for light automation. If you require more force, step up to the SCJ40, which provides 628 N of push at 0.5 MPa. For applications where the stroke is fixed and never needs field adjustment, the standard SC32 series offers a simpler, cost-effective alternative.
As a direct replacement, this cylinder matches any AirTAC SCJ32 with a 500 mm nominal stroke, 100 mm adjust range, PT ports, and a built-in magnet. For strokes of this length, ensure the rod is guided externally if significant side loads are present, or consider a guided cylinder to prevent rod bending and premature seal wear.
Adjustable-stroke checklist
At the standard 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. The maximum push force at 0.9 MPa is 724 N.
A rear-cap adjusting screw limits the piston's retraction stroke end. By turning the screw, you can shorten the effective stroke by up to 100 mm from the 500 mm nominal maximum, providing a precise, mechanical end-stop that is set once and remains fixed during operation.
