Airtac MSBL Aluminum Alloy Mini Cylinder MSBL40X60U
The AirTAC Airtac MSBL Aluminum Alloy Mini Cylinder MSBL40X60U is a genuine single acting, push (spring return) aluminum-barrel mini round cylinder with a Ø40mm bore and 60mm 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 MSBL40X60U
The AirTAC MSBL40X60U is a 40mm bore, 60mm stroke single-acting push-type mini cylinder. Air extends the rod, while an internal spring retracts it to a fail-safe home. It yields a usable push force of 439.6 N at 0.5 MPa and 690.8 N at 0.7 MPa. The 60mm stroke suits short ejection or clamping tasks.
This U-coded SKU features a rigid flat-end back cover. It uses a G1/4 port and an M12x1.25 rod-end thread. A riveted rolling-packed aluminum barrel and a 20 um hard-chrome plated carbon-steel rod ensure durability. Lacking the -S suffix, this specific SKU cannot host CMSG or DMSG position sensors. End-of-stroke impact is absorbed by a fixed rubber bumper, not an adjustable air cushion.

| 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 MSBL40X60U Is Used
Injection Mold Ejection
Uses 439.6 N at 0.5 MPa to push finished plastic parts out of an injection mold cavity, relying on the spring to safely retract the pin when air is cut.
Packaging Flap Folding
Applies 690.8 N at 0.7 MPa to fold cardboard carton flaps on a packaging line, with the spring ensuring the folder retracts clear of the product flow.
Woodworking Press
Delivers 60mm of stroke to press thin veneer sheets onto MDF panels, utilizing the fixed rubber bumper to soften the end impact during rapid cycling.
Is the Airtac MSBL Aluminum Alloy Mini Cylinder MSBL40X60U the Right Cylinder?
For sizing, the MSBL40X60U delivers 439.6 N at 0.5 MPa. Stepping down, the 32mm bore provides 281.3 N at 0.5 MPa; stepping up is unavailable as 40mm is the largest single-acting MSBL bore. Minimum operating pressure is 0.2 MPa to overcome the return spring. Choose this over an MTBL when you need air to push, not pull. Unlike a double-acting MBL, it only needs a 3/2 valve and one air line. Never apply external load during the spring return stroke; the small return spring is only meant to retract the rod itself. For 60mm strokes, side-load risk is moderate, so guide the load externally and use a U flat-end back cover for rigid alignment.
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 MSBL40X60U FAQ
The usable push force is 439.6 N at 0.5 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 return spring.
No. Because this SKU lacks the -S suffix for a built-in magnet, it cannot host CMSG reed or DMSG electronic sensors. You must select an MSBL40X60S variant for position detection.
