About the Airtac SCJ32 Standard Cylinder SCJ32X100-75S
The SCJ32X100-75S is a double-acting, single-rod pneumatic cylinder that puts field-adjustable stroke control into a compact 32 mm bore package. Its rear-cap adjusting screw lets you shorten the stroke end by up to 75 mm, making it ideal for commissioning trials, format changeovers, and wear take-up on light automation cells. The 12 mm diameter piston rod and PT1/8 port deliver a push force of 402 N at 0.5 MPa, rising to 724 N at the maximum operating pressure of 0.9 MPa.
This model includes a built-in magnet (-S suffix), so standard CMSG, DMSG, or EMSG reed and solid-state sensors clamp directly onto the tie-rod barrel for reliable end-of-stroke detection. The body length (A dimension) is 182 mm, and the adjustable air cushion decelerates the piston smoothly at both ends. As a genuine AirTAC component, it matches the original SCJ32X100-75S in bore, nominal stroke, adjust range, PT port, and basic mounting configuration.
Airtac SCJ32 Standard Cylinder SCJ32X100-75S Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X100-75S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 100 mm |
| Stroke adjustment | Up to 75 mm (rear adjusting screw) |
| Acting type | Double acting (single rod) |
| Port size | PT1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Adjustable, 21 mm |
| Max stroke | Up to 1000 mm |
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.
Theoretical Output Force (Ø32mm)
| 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.

Where the Airtac SCJ32 Standard Cylinder SCJ32X100-75S Is Used
Commissioning Fine-Tuning
During machine setup, the 75 mm adjustment screw allows engineers to precisely set the end-of-arm tooling position without fabricating custom hard stops, speeding up the debug phase.
Small-Part Sorting Gates
The adjustable stroke lets operators quickly change the opening width of a diverter gate on a conveyor line to handle different product sizes, all without mechanical modifications.
Wear Compensation in Clamping
In light-duty clamping fixtures, the stroke can be periodically adjusted to take up for jaw or pad wear, maintaining consistent clamping force over the tooling's service life.
Is the Airtac SCJ32 Standard Cylinder SCJ32X100-75S the Right Cylinder?
Choose the SCJ32X100-75S when you need to dial in a precise stroke end position within a 75 mm window without swapping cylinders. If the 402 N push force at 0.5 MPa is marginal, stepping up to the SCJ40 series provides 628 N of push force in a similar body length. For applications that do not require stroke adjustability, the fixed-stroke SC32X100 is a simpler, cost-effective alternative. When replacing this unit, match it with another AirTAC SCJ32X100-75S to ensure identical bore, nominal stroke, adjust range, PT port, and the integrated magnet for sensor compatibility.
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 SCJ32X100-75S FAQ
This 32 mm bore cylinder generates 402 N of push force and 345 N of pull force at 0.5 MPa. At the maximum operating pressure of 0.9 MPa, the push force increases to 724 N.
You can, if the application benefits from field-adjustable stroke. The SCJ32X100-75S has a slightly longer body to house the adjusting screw but shares the same 12 mm rod, PT1/8 port, and basic mounting footprint. Ensure the 75 mm adjustment range does not interfere with your machine's cycle.
