The AirTAC Airtac SCJ32 Standard Cylinder SCJ32X175-50 is a genuine double-acting SINGLE-ROD air cylinder with a rear-cap ADJUSTING SCREW: the stroke end is field-adjustable within a 50 mm range without swapping the cylinder. Ø32mm bore, 175mm nominal stroke, PT1/8 ports and adjustable end cushioning.
The SCJ32X175-50 is a double-acting, single-rod pneumatic cylinder that puts stroke-end fine-tuning directly into the rear cap. With a 32 mm bore and a 12 mm rod, it delivers 402 N of push force at 0.5 MPa, making it a compact workhorse for light positioning tasks. The integrated adjusting screw provides a full 50 mm of field-adjustable range, so you can dial in the exact stroke end position without adding external hard stops or swapping the cylinder body.
This model uses a PT1/8 port and an M10x1.25 rod thread, with a 21 mm air cushion at each end to quietly decelerate the piston. The tie-rod body length (A dimension) is 182 mm, keeping the overall envelope predictable. Because the stroke is adjustable, it excels in commissioning trials where the final travel needs to be found empirically, or on fixtures that undergo frequent format changes.

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.

The 50 mm screw adjustment lets technicians dial in the exact stroke end during machine bring-up, eliminating the need to machine custom stops or swap cylinders to find the optimal travel.
On packaging lines that run multiple box sizes, the adjustable stroke allows operators to quickly reset the pusher stroke length for a new format without mechanical rework, reducing downtime.
In clamping or pressing fixtures, the screw can be advanced slightly over time to take up mechanical wear in tooling, maintaining consistent clamp force and position without replacing parts.
Choose the SCJ32X175-50 when you need to fine-tune the stroke end on the machine. If your load requires more push force, stepping up to the 40 mm bore provides 628 N at the same 0.5 MPa pressure. For applications where the stroke is fixed and never changes, the standard SC32 series offers the same force and mounting without the adjusting mechanism. This cylinder is a direct replacement for another AirTAC SCJ32 adjustable-stroke unit with a 175 mm nominal stroke, 50 mm adjustment range, PT ports, and basic mounting; verify the magnet option if sensors are in use.
Adjustable-stroke checklist
At the standard 0.5 MPa operating pressure, it generates 402 N of push force and 345 N of pull force. The maximum push force at 0.9 MPa is 724 N. Because it is a single-rod cylinder, the pull force is always lower than the push force due to the rod area.
Yes, if you need the ability to adjust the stroke end. The SCJ32X175-50 shares the same bore, port, and mounting dimensions as the SC32 series, but the rear cap includes the adjusting screw. Ensure the added length of the screw housing fits your machine envelope and that you set the screw to match your required stroke.
