Airtac SCJ32 Standard Cylinder SCJ32X75-75S
The AirTAC SCJ32 Standard Cylinder SCJ32X75-75S is a genuine double-acting DOUBLE-ROD air cylinder whose rear rod carries the stroke ADJUSTER: the stroke end is field-adjustable within a 75 mm range without swapping the cylinder. Ø32mm bore, 75mm nominal stroke, PT1/8 ports and adjustable end cushioning.

About the Airtac SCJ32 Standard Cylinder SCJ32X75-75S
The SCJ32X75-75S is a compact adjustable-stroke air cylinder that puts fine end-position tuning directly into the rear cap. The 75 mm adjustment range lets you shorten the nominal 75 mm stroke on the fly, which is invaluable during commissioning or when a machine needs to handle multiple product sizes without swapping cylinders.
A built-in magnet (the -S suffix) allows CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the tie-rod barrel, giving you reliable, non-contact end-of-stroke or mid-stroke position feedback. The cylinder uses PT1/8 ports, an M10x1.25 rod thread, and a 21 mm air cushion to decelerate the piston quietly at the end of travel. Its body length A is 182 mm, keeping the overall envelope tight for space-constrained automation cells.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 kgf | |
SCJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative), lower than a single-rod SC push of the same bore. Actual usable force is lower than theoretical due to friction and back-pressure; size with a safety margin.

Where the Airtac SCJ32 Standard Cylinder SCJ32X75-75S Is Used
Commissioning & Setup
The 75 mm adjustment screw lets technicians dial in the exact retract or extend end position during machine bring-up without changing hard stops, cutting setup time on packaging and assembly lines.
Multi-Format Diverters
Adjust the stroke end to match different lane widths or product sizes on a conveyor. One cylinder handles multiple formats, reducing changeover parts inventory.
Wear Take-Up
As gripper pads or tooling tips wear, the rear adjusting screw can be advanced to compensate, maintaining consistent clamping force and part contact without replacing the actuator.
Is the Airtac SCJ32 Standard Cylinder SCJ32X75-75S the Right Cylinder?
Choose the SCJ32 when you need a light-duty, field-adjustable stroke in a small footprint. For applications where the stroke is fixed and never changes, the standard SC32 fixed-stroke cylinder is a simpler, more economical choice. This SCJ32X75-75S is a direct replacement for any AirTAC SCJ32 with a 75 mm nominal stroke, 75 mm adjust range, PT ports, and a magnet, provided the mounting style matches.
At a 75 mm stroke, rod buckling is not a concern under normal axial loads, but always align the rod with the load path to prevent side-loading the bearing. If you need to guide the load externally, consider pairing the cylinder with a linear rail rather than relying on the rod bearing alone.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-75)
- ✓ Required force at your working pressure
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Set the rear adjusting screw, then lock it before running.
- check Adjust end cushion screws for smooth stops.
- check Use SCJ mounting accessory (FA / LB / TC / TCM1).
- check Installation by qualified personnel per AirTAC docs.
Airtac SCJ32 Standard Cylinder SCJ32X75-75S FAQ
At 0.5 MPa, the push force is 402 N and the pull force is 345 N (the difference is due to the 12 mm single piston rod). At the maximum operating pressure of 0.9 MPa, the push force reaches 724 N. The adjusting screw does not change the cylinder's force output.
Yes, if the mounting and port configuration match. The SCJ32 body is slightly longer to accommodate the adjusting screw (A length 182 mm). Ensure you have the extra space behind the rear cap. The -S magnet option must also match if you are using barrel-mounted sensors.
