Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL40X10U
The AirTAC Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL40X10U is a genuine single acting, pull (spring extend) aluminum-barrel mini round cylinder with a Ø40mm bore and 10mm stroke, G1/4 air ports and a fixed rubber bumper. Air drives the pull (work) stroke and the spring returns the rod — it rests extended on air loss.

About the Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL40X10U
The AirTAC MTBL40X10U is a compact single-acting pull-type mini cylinder with a 40mm bore and 10mm stroke. Air retracts the rod while an internal spring extends it, yielding a fail-safe extended home position on air loss. It develops 339.1 N of usable pull force at 0.5 MPa and 550.1 N at 0.7 MPa. The U code denotes a flat-end back cover for rigid mounting.
This unit features a riveted rolling-packed aluminum barrel and a 20 µm hard-chrome plated carbon-steel rod. It lacks a built-in magnet, so it cannot accept CMSG, DMSG, or EMSG position sensors. A fixed rubber bumper absorbs end-of-stroke impact, and its overall length equals A plus twice the stroke.

| 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 100 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 Pull Force (Ø40mm)
| Pressure | Pull force (net of spring) |
|---|---|
| 0.5 MPa | 339.1 N |
| 0.7 MPa | 550.1 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 MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL40X10U Is Used
Press Die Stripping
Pulls a stripper plate inward during press retraction, using the 339.1 N pull force to clear stamped blanks before the spring extends the rod back out.
Vacuum Gate Seating
Draws a vacuum chamber door closed against atmospheric pressure, relying on the fail-safe extended home to mechanically lock the gate open on air loss.
Brake Caliper Release
Retracts a holding caliper in a light packaging machine, with the fixed rubber bumper handling the abrupt 10mm stroke impact without adjustable cushions.
Is the Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL40X10U the Right Cylinder?
Choose the 40mm bore when substantial pulling force is needed; if less is required, the 32mm bore yields 224.8 N at 0.5 MPa. For higher force, 40mm is the largest single-acting pull option available. The MTBL provides a fail-safe extended rest, unlike the MSBL which fails safe retracted. A double-acting MBL offers higher net force but lacks an automatic spring return. Minimum working pressure is 0.2 MPa. Apply no external load during the spring return stroke. Replacement match: 40mm bore, 10mm stroke, G1/4 port, PT thread, U flat-end cover, no magnet.
Quick checklist
- ✓ Usable pull force at your pressure (min 0.2 MPa)
- ✓ Fail-safe rest position (extended)
- ✓ 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 MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL40X10U FAQ
It requires 0.2-1.0 MPa operating pressure (minimum 0.2 MPa to overcome the spring). Usable pull force, net of the spring, is 22.6 N at 0.2 MPa, 233.6 N at 0.4 MPa, 339.1 N at 0.5 MPa, and 550.1 N at 0.7 MPa.
No. Because the model code lacks an 'S' suffix, this specific SKU has no built-in magnet and cannot accept CMSG reed or DMSG/EMSG electronic sensors. It also uses a fixed rubber bumper instead of an adjustable air cushion.
