The AirTAC Airtac SCJ80 Standard Cylinder SCJ80X150-100TC 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 SCJ80X150-100TC is an 80 mm bore, double-acting single-rod cylinder offering a field-adjustable stroke end via a rear-cap screw. With a nominal 150 mm stroke and a 100 mm adjustment range, it delivers a push force of 2513 N at 0.5 MPa, making it a robust solution for applications requiring on-machine fine-tuning.
This model includes a centre trunnion (TC) mount for pivoting loads, supplied with the TCM1 bracket. The 25 mm diameter rod, PT3/8 ports, and 28 mm air cushion provide reliable deceleration, while the tie-rod construction ensures serviceability in demanding industrial environments.

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.
Adjust the stroke end by up to 100 mm to accommodate different box or pallet sizes on a packaging line without changing the cylinder or adding mechanical stops.
Fine-tune the clamp position as tooling or workpieces wear down over time, maintaining consistent clamping force without reprogramming the machine.
Set the precise end point of a diverter arm on a conveyor system during commissioning, allowing quick adjustments for smooth product transfer.
Choose this 80 mm bore when the 63 mm model's 1559 N push force at 0.5 MPa is insufficient, but step up to the 100 mm bore if you require 3927 N. The 100 mm adjustment range is ideal for processes with multiple product heights or significant wear take-up. For fixed-stroke applications, consider the standard SC series.
Direct replacement requires an AirTAC SCJ80 cylinder with a 150 mm nominal stroke, 100 mm adjust range, PT ports, and TC mounting (F-SC80TC). At this 150 mm stroke, side-loading is typically not a primary concern, but always ensure the rod is aligned with the load path to prevent premature seal wear.
Adjustable-stroke checklist
A screw in the rear cap limits the piston's retraction stroke end. Turning the screw shortens the effective stroke by up to 100 mm from the 150 mm nominal maximum, allowing you to dial in the exact position needed on the machine.
At 0.5 MPa, it provides 2513 N of push force and 2268 N of pull force. The push force is higher because the single rod reduces the effective piston area on the return side.
