About the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X175SCA
The AirTAC MBL40X175SCA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers a robust 628 N push force at 0.5 MPa, making it well-suited for 175 mm stroke actuation tasks that require substantial push and pull power. The riveted rolling-packed barrel keeps the body light and sealed permanently, meaning it is not designed to be disassembled or rebuilt like a heavy tie-rod cylinder.
This specific SKU includes a built-in -S magnet for CMSG, DMSG, or EMSG sensor switches, allowing precise end-of-stroke detection. It also features a CA pivot back cover, allowing the cylinder to swing on a pin to accommodate arcing or angular loads. The carbon-steel piston rod features a 20 um hard-chrome plating for high wear and corrosion resistance, paired with a heterogeneous two-way piston seal that retains grease for a long service life.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X175SCA Is Used
Textile Loom Tensioning
Leverages the 628 N push force and CA pivot back cover to maintain consistent fabric tension on a weaving loom, absorbing angular movement during high-speed operation.
Package Sorting Diverter
Uses the 175 mm stroke to push parcels onto adjacent chutes, relying on the -S magnet and DMSG electronic sensor to confirm diversion before the belt advances.
Palletizing Stop Gate
Acts as a compact 40 mm bore stopper on a packaging line, using its 528 N pull force to retract the gate and allow pallet flow without occupying excessive frame space.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X175SCA the Right Cylinder?
Selecting this 40 mm bore model provides 628 N push at 0.5 MPa. If you need less force, stepping down to the 32 mm bore yields 402 N push; if your application demands more power, the 50 mm bore provides 981 N push. Because this 175 mm stroke is substantial for a mini cylinder, the relatively small Ø16 rod has limited side-load tolerance—an external guide or the CA pivot back cover on this SKU is essential to prevent rod-bearing bending under lateral stress.
Note that the base MBL uses a fixed rubber bumper to soften end-of-stroke impact, not an adjustable air cushion (for adjustable cushioning, choose the MBLC variant). Furthermore, this cylinder does not hold its position if air pressure is lost; the rod will drift or drop. If load holding is required without live pressure, integrate an external rod lock or a pilot-operated check valve. This exact replacement matches: 40 mm bore, 175 mm stroke, G1/4 port, PT thread, CA pivot back cover, and an -S 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 MBL40X175SCA FAQ
This 40 mm bore cylinder provides a push force of 628 N and a pull force of 528 N at 0.5 MPa. At 0.7 MPa, the push force increases to 880 N, with a maximum theoretical force of 128 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
This model includes a -S magnet for mounting CMSG (reed) or DMSG/EMSG (electronic) sensor switches. However, it uses a fixed rubber bumper for end-of-stroke cushioning, which is not adjustable. If your application requires adjustable air cushioning to absorb heavier kinetic energy, you should select the MBLC variant instead.
