About the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X150SU
The AirTAC MBL40X150SU is a double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers a robust 628 N push and 528 N pull force at 0.5 MPa, making it ideal for mid-range actuation over its 150 mm stroke. The riveted rolling-packed barrel crimps the front and rear covers directly to the tube, yielding a lightweight footprint that is not designed to be disassembled like a traditional tie-rod body.
This specific SKU features a built-in magnet (-S) for rod position detection via CMSG reed or DMSG and EMSG electronic switches. It uses a G1/4 port paired with a Ø16 mm carbon-steel rod plated with 20 µm hard chrome for high wear resistance. The U flat-end back cover provides a rigid, fixed rear mounting face. End-of-stroke deceleration is handled by 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 MBL40X150SU Is Used
PCB Depaneling Saw
Provides the 628 N push force needed to advance a depaneling saw blade through a rigid FR4 circuit board array over the full 150 mm stroke.
Carton Flap Folder
Uses the integrated DMSG electronic sensor to confirm rod extension for folding secondary packaging flaps before a sealing head applies tape.
Pallet Diverter Gate
Actuates a routing gate on a compact conveyor line, utilizing the rigid U flat-end back cover to anchor firmly against shifting lateral loads.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X150SU the Right Cylinder?
Stepping down to the 32 mm bore drops the 0.5 MPa push force to 402 N, while stepping up to the 50 mm bore raises it to 981 N. Because this 150 mm stroke is substantial for a mini cylinder, the relatively small Ø16 mm rod has limited side-load tolerance; an external guide or a pivot bracket is recommended to prevent rod-bearing bending under lateral stress. If your process requires adjustable end-of-stroke cushioning for heavier moving masses, select the MBLC variant instead of the base MBL. For exact replacement, match the 40 mm bore, 150 mm stroke, G1/4 port, PT thread, U flat-end cover, and the -S magnet. Note that this cylinder drifts when air is exhausted, so an external rod lock is required to hold loads safely.
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 MBL40X150SU 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, with a theoretical maximum of 128 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
No, the base MBL uses a fixed rubber bumper to soften end-of-stroke impact, not an adjustable cushion screw. If you need adjustable air cushioning for heavier or faster moving loads, you must step up to the MBLC variant.
