The AirTAC Airtac SCJ100 Standard Cylinder SCJ100X400-10S is a genuine double-acting SINGLE-ROD air cylinder with a rear-cap ADJUSTING SCREW: the stroke end is field-adjustable within a 10 mm range without swapping the cylinder. Ø100mm bore, 400mm nominal stroke, PT1/2 ports and adjustable end cushioning.
The SCJ100X400-10S delivers substantial force in a field-tunable package, generating 3927 N of push and 3681 N of pull at 0.5 MPa. Its rear-cap adjusting screw provides a precise 10 mm stroke-end reduction range, letting commissioning engineers dial in the exact stop position for a 400 mm nominal stroke without swapping the cylinder or machining external hard stops.
This 100 mm bore tie-rod cylinder uses a 25 mm diameter piston rod and PT1/2 ports, with an adjustable air cushion that decelerates the load over the final 29 mm of travel. The built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors along the barrel for reliable, non-contact end-of-stroke detection, simplifying integration into automated sequences.

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 | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 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.

Fine-tune the diverter gate's end position to perfectly align with different product widths, eliminating jams during format changeovers on packaging lines.
Set the exact clamp closure point for a family of parts, using the 10 mm screw adjustment to accommodate minor thickness variations without reprogramming the machine.
Dial in the final press depth during prototype runs or after tooling wear, using the adjustable stroke end to maintain consistent assembly force and part quality.
Choose the SCJ100X400-10S when you need the 3927 N push force of a 100 mm bore but require on-machine stroke-end fine-tuning within a 10 mm window. If your application demands more force, stepping up to the 125 mm bore provides 6136 N of push at the same pressure. For fixed-stroke applications where adjustability is not required, the standard SC100X400 is a simpler alternative. When replacing this unit, match the 100 mm bore, 400 mm nominal stroke, 10 mm adjust range, PT port thread, and the integrated magnet; the basic mounting style accepts foot (LB) or flange (FA) accessories if needed later. At this 400 mm stroke, be mindful of side loads—if the rod is not guided externally, consider adding a guide rail or switching to a guided cylinder to prevent rod bending and premature seal wear.
Adjustable-stroke checklist
At the standard 0.5 MPa operating pressure, this single-rod cylinder generates 3927 N of push force (using the full 100 mm bore area) and 3681 N of pull force (subtracting the 25 mm rod area). At the maximum operating pressure of 1.0 MPa, the theoretical push force reaches 7854 N.
Yes, the SCJ100X400-10S shares the identical 100 mm bore, PT1/2 ports, and SC-family mounting accessories. It is a direct dimensional replacement that adds a 10 mm rear stroke-end adjustment screw, giving you the ability to fine-tune the stop position without changing the cylinder's overall envelope.
