The AirTAC Airtac SCJ32 Standard Cylinder SCJ32X350-30S 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, 350mm nominal stroke, PT1/8 ports and adjustable end cushioning.
The SCJ32X350-30S is a double-acting, single-rod pneumatic cylinder with a rear adjusting screw that provides 30 mm of field-adjustable stroke end control. This allows fine-tuning of the 350 mm nominal stroke without replacing the cylinder, ideal for commissioning and format changes. The built-in magnet enables direct mounting of CMSG/DMSG/EMSG sensors for precise end-of-stroke detection.
At 0.5 MPa, it delivers 402 N of push force and 345 N of pull force, with a 12 mm diameter piston rod and PT1/8 ports. The adjustable air cushion provides smooth deceleration over a 21 mm length, and the body length A(SCJ) is 182 mm. This genuine AirTAC cylinder is a reliable choice for applications requiring stroke flexibility in a compact 32 mm bore package.

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 position of a material stop or pusher during machine commissioning. The 30 mm adjustment range allows operators to dial in the exact stroke without swapping shims or hard stops, saving significant setup time.
Use the adjustable stroke to precisely control the diverting gate position on a conveyor for different product sizes. The built-in magnet provides sensor feedback to the PLC, confirming the gate has reached the adjusted end position.
In clamping or pressing fixtures, the 30 mm adjustment can compensate for tooling wear or material thickness variations over time. This maintains consistent clamping force without reprogramming the machine or replacing the actuator.
Select the SCJ32 when 402 N of push force at 0.5 MPa is sufficient and you need the 30 mm stroke adjustment range. If more force is required, step up to the SCJ40 bore, which provides 628 N of push force at the same pressure. For applications where the stroke is permanently fixed and never needs field adjustment, the standard SC32 fixed-stroke cylinder is a simpler, more cost-effective alternative.
This model is a direct replacement for another AirTAC SCJ32X350-30S cylinder with a magnet, matching the 350 mm nominal stroke, 30 mm adjust range, PT port thread, and basic mounting. For strokes of 300 mm or more, be mindful of side loads on the 12 mm rod; if the load is not guided, add an external guide rail or consider a guided cylinder to prevent rod bending and ensure long seal life.
Adjustable-stroke checklist
At the standard operating pressure of 0.5 MPa, this cylinder provides 402 N of push force and 345 N of pull force. The push force is higher because it acts on the full 32 mm bore area, while the pull force is slightly reduced by the 12 mm piston rod area. The maximum push force at 0.9 MPa is 724 N.
Yes, provided the bore, nominal stroke, port thread, and mounting match. The SCJ32X350-30S has the same body length and mounting dimensions as the SC32, but adds a rear adjusting screw for 30 mm of stroke-end adjustability. Ensure you have clearance for the adjusting screw at the rear cap. The magnet option (-S) must also match if you are using sensors.
