The AirTAC Airtac SCJ80 Standard Cylinder SCJ80X150-100H 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. Ø80mm bore, 150mm nominal stroke, PT3/8 ports and adjustable end cushioning.
The SCJ80X150-100H is a double-acting, single-rod pneumatic cylinder with a field-adjustable stroke end, delivering 2513 N of push force at 0.5 MPa. Its rear-cap adjusting screw provides up to 100 mm of stroke shortening, enabling precise end-position tuning for commissioning or format changes without replacing the cylinder. The 25 mm diameter piston rod and PT3/8 ports handle demanding industrial tasks.
Built with a tie-rod construction and a 239 mm body length, this model is fitted with Viton (FKM) seals, extending its operating temperature range to 0–150 °C for high-heat environments. The adjustable air cushion decelerates the piston smoothly at the stroke end, protecting the end cap from impact. This is a genuine AirTAC unit, ready for integration into automated machinery requiring robust, heat-resistant actuation.

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 | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 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 pusher arm on a new assembly line by up to 100 mm to dial in the exact stop point without machining new brackets or swapping cylinders.
Adjust a part stop on a conveyor running through a curing oven. The Viton seals withstand the 0–150 °C ambient temperature, and the stroke can be tweaked for different product lengths.
Compensate for the gradual wear of friction pads in a high-cycle clamping fixture. The 100 mm adjustment screw lets operators restore the full clamp force position over the tool's lifetime.
Choose the SCJ80X150-100H when you need to fine-tune the stroke end point by up to 100 mm on the machine, a capability a fixed-stroke SC cylinder cannot offer. If your force requirement is lower, stepping down to a 63 mm bore reduces push force to 1559 N at 0.5 MPa. For higher force, the 100 mm bore provides 3927 N. If your application does not require stroke adjustment, a standard SC80X150 fixed-stroke cylinder is a simpler, more cost-effective choice.
For replacement, match this model with another AirTAC SCJ adjustable-stroke cylinder of 80 mm bore, 150 mm nominal stroke, a 100 mm adjustment range, PT port thread, and Viton seals. The 150 mm stroke is well within the 1500 mm maximum standard stroke for this bore, ensuring stable rod guidance. If side loads are present, consider an external guide rail or a guided cylinder to prevent rod bending and seal wear.
Adjustable-stroke checklist
At the standard 0.5 MPa operating pressure, the push force is 2513 N and the pull force is 2268 N. The push force is higher because the single rod reduces the effective piston area on the retract side. At the maximum operating pressure of 1.0 MPa, the theoretical push force reaches 5026 N.
Only if your mounting allows for the slightly longer body length of the SCJ series (239 mm for the 80 bore). The adjustable stroke is a bonus feature. For a direct dimensional drop-in without the adjustment screw, the fixed-stroke SC80X150 is the correct match. Ensure the port size (PT3/8) and mounting style are identical.
