Airtac MSBL Aluminum Alloy Mini Cylinder MSBL40X150CA
The AirTAC Airtac MSBL Aluminum Alloy Mini Cylinder MSBL40X150CA is a genuine single acting, push (spring return) aluminum-barrel mini round cylinder with a Ø40mm bore and 150mm 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 MSBL40X150CA
The AirTAC MSBL40X150CA is a compact, single-acting push-type mini cylinder with a 40mm bore and 150mm stroke. Air extends the rod to drive the work stroke, while an internal spring retracts it when air is released, providing a fail-safe retracted home position. It delivers a usable push force of 439.6 N at 0.5 MPa and 690.8 N at 0.7 MPa. The 150mm stroke is the maximum standard length for this series, making it ideal for deep ejection or long-travel clamping tasks.
This SKU features a CA pivot/clevis back cover, allowing the cylinder body to swing on a pin to absorb arcing and angular loads during motion. It uses a G1/4 port and a 16mm hard-chrome carbon-steel rod. Because this configuration lacks the -S magnet code, it cannot accept CMSG, DMSG, or EMSG position sensors. The riveted rolling-packed aluminum barrel and heterogeneous grease-retaining piston seal ensure durable, leak-free operation in tight spaces.

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 |

Where the Airtac MSBL Aluminum Alloy Mini Cylinder MSBL40X150CA Is Used
Stamping Press Ejector
Ejects deep-drawn metal cups from a stamping die. The 150mm stroke reaches deep into the die, and the 690.8 N push force at 0.7 MPa reliably frees the part before the spring safely retracts the rod clear of the tooling.
Automated Welding Clamp
Clamps heavy chassis frames in a robotic welding cell. The CA pivot cover accommodates frame misalignment, while the spring-return design guarantees the clamp opens to a safe home position if compressed air is lost.
Woodworking Gate Diverter
Pushes a diverter gate to route long timber boards on a conveyor. The 40mm bore provides the force needed to move the heavy wood gate, and the CA clevis allows the mechanism to swing freely without binding.
Is the Airtac MSBL Aluminum Alloy Mini Cylinder MSBL40X150CA the Right Cylinder?
At the maximum standard stroke of 150mm on a 40mm bore, side-load and rod bending become critical factors. Use external guides or linear rails to support the load, and rely on the CA pivot back cover to prevent rod binding. If 439.6 N at 0.5 MPa is insufficient, step up to a double-acting MBL40 for force in both directions, or consider a larger ISO 15552 cylinder. If you need less force, step down to the 32mm bore, which provides 281.3 N at 0.5 MPa.
Remember that the return spring opposes the air stroke, so the usable push force is lower than a same-bore double-acting MBL. A minimum working pressure of 0.2 MPa is required to overcome the spring. Apply NO external load during the spring return stroke, as the return force is small and only meant to retract the rod itself. The fixed rubber bumper softens end impact but is not an adjustable air cushion or a locking device.
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 MSBL40X150CA FAQ
The usable push force (net of the return spring) is 62.8 N at 0.2 MPa, 188.4 N at 0.3 MPa, 314.0 N at 0.4 MPa, 439.6 N at 0.5 MPa, 565.2 N at 0.6 MPa, and 690.8 N at 0.7 MPa. The operating pressure range is 0.2-1.0 MPa, with a 0.2 MPa minimum required to overcome the internal spring.
No. This specific SKU lacks the -S code, meaning it has no built-in magnet. To use AirTAC CMSG (reed), DMSG, or EMSG (electronic) sensor switches for end-of-stroke detection, you must select a model with the -S suffix, such as MSBL40X150SCA.
