The AirTAC Airtac AIRTAC SCJ63 Standard Cylinder SCJ63X500-100S 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. Ø63mm bore, 500mm nominal stroke, PT1/4 ports and adjustable end cushioning.
The SCJ63X500-100S is a double-acting, single-rod pneumatic cylinder that puts a 100 mm field-adjustable stroke range at your fingertips, letting you dial in the exact end position on a 500 mm nominal body without swapping hardware. Its 20 mm rod and 28 mm air cushion handle 1559 N of push force at 0.5 MPa, rising to 2805 N at the 0.9 MPa maximum operating pressure.
A built-in magnet is factory-installed, so CMSG, DMSG, or EMSG sensors clamp directly onto the tie-rod barrel for non-contact position sensing. The cylinder uses PT1/4 ports and an M16x1.5 rod thread, with a body length A of 197 mm plus stroke, making it a drop-in adjustable solution for format changes or commissioning fine-tuning on packaging and assembly machinery.

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 | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 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.
Adjust the stroke end by up to 100 mm when switching between box sizes, eliminating mechanical stop changes and reducing changeover time on case erectors and cartoners.
Fine-tune the actuator end position during machine commissioning and wear take-up without draining the air system or removing the cylinder from its mounting.
Set the precise gate opening for different product lanes on a conveyor. The rear screw lets operators quickly match the stroke to product width.
Step up to an SCJ80 bore if you need more than 1559 N push at 0.5 MPa—the 80 mm bore delivers 2513 N. For a simpler fixed-stroke design where the end position never changes, the SC63 is the direct alternative. This SCJ63X500-100S replaces another AirTAC SCJ63 with a 500 mm nominal stroke, 100 mm adjust range, PT ports, basic mounting, and a magnet-equipped barrel. At 500 mm, rod bending under side load becomes a real concern; if the load is not guided externally, add a linear guide or switch to a guided cylinder to protect the rod and bearing.
Adjustable-stroke checklist
At 0.5 MPa, it generates 1559 N pushing and 1402 N pulling (the pull force is lower because of the single 20 mm rod). At the maximum operating pressure of 0.9 MPa, push force reaches 2805 N.
Yes, if you need the 100 mm adjustable stroke end. The SCJ63 shares the same bore, rod, and port dimensions as the SC63. Ensure the slightly longer body length fits your space and match the magnet option (S) and PT port thread.
