About the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X150-CA
The AirTAC MBL40X150-CA is a double-acting aluminum mini round cylinder engineered for compact machines requiring a 150 mm stroke. It delivers a robust 628 N push force at 0.5 MPa, utilizing a G1/4 port and a Ø16 mm carbon steel rod with hard chrome plating for wear resistance. The riveted rolling-packed barrel keeps the overall footprint small and lightweight, making it ideal for tight assembly zones where space is restricted.
This specific SKU features a CA pivot (clevis) back cover, allowing the cylinder body to swing on a pin to accommodate arcing or angular loads during movement. Because this configuration lacks the -S suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor. The internal end-of-stroke deceleration relies on a fixed rubber bumper, which softens impact but does not lock the rod in place if air pressure is lost.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X150-CA Is Used
Textile Loom Tensioning
Provides 528 N of pull at 0.5 MPa to maintain yarn tension arms on automated weaving looms, using the CA pivot to absorb minor thread alignment shifts.
Bottling Line Diverter
Actuates a 150 mm swing gate to route plastic bottles between packaging lanes, where the compact riveted barrel fits within the 40 mm frame gap of the conveyor.
Carton Flap Folder
Drives a mechanical arm to fold corrugated cardboard flaps at high speed, relying on the fixed rubber bumper to soften the 628 N end-of-stroke impact.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X150-CA the Right Cylinder?
If your application requires less force, stepping down to the 32 mm bore yields 402 N push at 0.5 MPa, while moving up to the 50 mm bore increases output to 981 N. Choose the MBLC variant if your cycle speed demands an adjustable air cushion rather than the fixed rubber bumper found here, or select the MSBL/MTBL models for single-acting push or pull operations.
At 150 mm of stroke, the unsupported Ø16 mm piston rod is susceptible to bending under side loads; utilizing the CA pivot back cover with an SDB bracket helps mitigate angular stress, though an external guide rail is recommended for heavy offset loads. Note that this MBL40X150-CA cannot hold its load position upon exhaust or pressure loss—the rod will drift. For replacement, match the 40 mm bore, 150 mm stroke, G1/4 port, PT thread, CA back cover, and no magnet.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ 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 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (LB / FA / SDB) and back cover (CA pivot / U flat-end).
- check Installation by qualified personnel per AirTAC docs.
Airtac MBL Aluminum Alloy Mini Cylinder MBL40X150-CA FAQ
At 0.5 MPa, this 40 mm bore cylinder provides 628 N of push force and 528 N of pull force. At 0.7 MPa, the push force increases to 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa.
No, this specific SKU lacks the -S suffix, meaning it has no built-in magnet and cannot accept CMSG, DMSG, or EMSG sensor switches. You must order an MBL40X150S-CA variant to enable electronic or reed switch position detection.
