About the Airtac SCJ32 Standard Cylinder SCJ32X275-75
The SCJ32X275-75 is a double-acting, single-rod tie-rod cylinder that puts precise stroke-end tuning at your fingertips. Its rear adjusting screw provides up to 75 mm of field-adjustable range on the 275 mm nominal stroke, eliminating the need for hard stops during commissioning or format changes. With a 12 mm diameter piston rod and PT1/8 ports, it delivers a push force of 402 N at 0.5 MPa, scaling to 724 N at the maximum operating pressure of 0.9 MPa.
This 32 mm bore cylinder is built for flexible integration, featuring an adjustable air cushion to decelerate the piston smoothly. The body length A measures 182 mm, making it a compact choice for space-constrained applications. As a genuine AirTAC product, it is backed by the quality and support expected from an authorized distributor, ensuring reliable performance in your pneumatic systems.
Airtac SCJ32 Standard Cylinder SCJ32X275-75 Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X275-75 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 275 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 SCJ32X275-75 Is Used
Commissioning & Setup
The 75 mm adjustment range allows engineers to dial in the exact stroke end position during machine setup, compensating for assembly tolerances without machining custom stops.
Wear Compensation
In clamping or pressing fixtures, the stroke can be gradually extended over time to compensate for tooling or pad wear, maintaining consistent clamping force without reprogramming.
Multi-Product Lines
Quickly adjust the stop position for different product sizes on a conveyor diverter or stopper, enabling rapid changeover between batches with a simple screw adjustment.
Is the Airtac SCJ32 Standard Cylinder SCJ32X275-75 the Right Cylinder?
Select the SCJ32X275-75 when you need to fine-tune the end position of a 275 mm stroke without swapping the cylinder. If the 402 N push force at 0.5 MPa is insufficient, stepping up to the 40 mm bore provides 628 N of push force. For applications requiring a fixed, non-adjustable stroke, the standard SC series is a more economical alternative. This model is a direct replacement for any AirTAC SCJ32X275-75 with PT ports and basic mounting.
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 SCJ32X275-75 FAQ
At the standard 0.5 MPa operating pressure, it generates 402 N of push force and 345 N of pull force due to the 12 mm rod. The push force increases to 724 N at the maximum operating pressure of 0.9 MPa.
Yes, the SCJ32X275-75 is a drop-in replacement for any AirTAC SCJ32X275-75 with basic mounting and PT ports. It matches the same body length and mounting footprint, adding the benefit of a 75 mm rear stroke adjustment.
