Airtac MSBL Aluminum Alloy Mini Cylinder MSBL40X75CA
The AirTAC Airtac MSBL Aluminum Alloy Mini Cylinder MSBL40X75CA is a genuine single acting, push (spring return) aluminum-barrel mini round cylinder with a Ø40mm bore and 75mm stroke, G1/4 air ports and a fixed rubber bumper. Air drives the push (work) stroke and the spring returns the rod — it rests retracted on air loss.

About the Airtac MSBL Aluminum Alloy Mini Cylinder MSBL40X75CA
The AirTAC MSBL40X75CA is a compact, single-acting push-type mini cylinder with a 40 mm bore and 75 mm stroke. Air extends the rod, while an internal spring retracts it, ensuring a fail-safe home position on air loss. It delivers a usable push force of 439.6 N at 0.5 MPa and 690.8 N at 0.7 MPa. The CA back cover provides a pivot/clevis mount for arcing loads.
This model uses a G1/4 port and a 16 mm carbon-steel rod with 20 um hard-chrome plating. It has a fixed rubber bumper, not an adjustable air cushion. Because this SKU lacks the -S suffix, it has no built-in magnet and cannot accept CMSG, DMSG, or EMSG position sensors. The riveted rolling-packed aluminum barrel keeps the body light for tight spaces.
Airtac MSBL Aluminum Alloy Mini Cylinder MSBL40X75CA Technical Specifications
| Model | Airtac MSBL Aluminum Alloy Mini Cylinder MSBL40X75CA |

| Stroke | 75 mm |
| Acting type | Single acting, push (spring return) |
| Port size | G1/4 |
| Rod thread | M12×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.2 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 50 – 800 mm/s |
| Cushion | Fixed rubber bumper |
| Max standard stroke | Up to 150 mm |
Single-acting minimum working pressure is 0.2 MPa (the air must overcome the return spring). Do not apply an external load during the spring return stroke. Thread options: PT / G / NPT.
Usable Push Force (Ø40mm)
| Pressure | Push force (net of spring) |
|---|---|
| 0.5 MPa | 439.6 N |
| 0.7 MPa | 690.8 N |
These are the usable single-acting forces after the return spring — lower than a same-bore double-acting MBL. Size with a margin.

Where the Airtac MSBL Aluminum Alloy Mini Cylinder MSBL40X75CA Is Used
Stamping Ejector
Ejects small stamped parts from a press die using 439.6 N at 0.5 MPa; the spring ensures the pin retracts clear of the tool on air loss.
Pivoted Clamp
Holds a curved tube for welding; the CA clevis allows the clamp arm to swing and follow the part's arc during the 75 mm stroke.
Packaging Flap
Pushes a carton flap closed on a packaging line; the single-acting design uses one 3/2 valve and returns the flap via spring when air stops.
Is the Airtac MSBL Aluminum Alloy Mini Cylinder MSBL40X75CA the Right Cylinder?
The 40 mm bore yields 439.6 N of push force at 0.5 MPa. If you need less force, step down to the 32 mm bore (281.3 N at 0.5 MPa). If you need force in both directions, use the double-acting MBL. The MSBL requires at least 0.2 MPa to overcome the return spring. The CA pivot bracket suits angular loads; apply no external load during the spring return stroke.
For a 75 mm stroke on this bore, manage side-load with an external guide. To replace this unit, match the 40 mm bore, 75 mm stroke, G1/4 port, PT thread, CA pivot back cover, and no magnet. If you need position feedback, switch to an MSBL40X75SCA and add a solid-state DMSG or EMSG switch.
Quick checklist
- ✓ Usable push force at your pressure (min 0.2 MPa)
- ✓ Fail-safe rest position (retracted)
- ✓ No external load on the spring return stroke
- ✓ Magnet (S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.2 – 1.0 MPa (min 0.2 to overcome the spring).
- check Apply no external load on the spring return stroke.
- check Avoid side load on the piston rod.
- check Use the correct mounting accessory (LB / FA / SDB) and back cover (CA / U).
- check Installation by qualified personnel per AirTAC docs.
Airtac MSBL Aluminum Alloy Mini Cylinder MSBL40X75CA FAQ
The usable push force (net of spring) is 439.6 N at 0.5 MPa and 690.8 N at 0.7 MPa. The minimum operating pressure is 0.2 MPa because the air must first overcome the internal return spring.
No. This SKU lacks the -S magnet suffix, so it cannot accept CMSG, DMSG, or EMSG switches. You must select an MSBL40X75SCA model for solid-state or reed switch position detection.
