About the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X175SU
The AirTAC MBL40X175SU is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. Operating with a 40mm bore and 175mm stroke, it generates 628N of push force and 528N of pull force at 0.5 MPa. The U suffix denotes a rigid flat-end rear cover, providing a stable fixed mounting footprint for straightforward linear actuation tasks.
Built with a riveted rolling-packed aluminum barrel, this unit is lightweight and permanently crimped rather than tie-rod assembled. The carbon steel piston rod features 20 um hard-chrome plating for wear resistance, while a heterogeneous two-way piston seal retains grease for extended cycle life. This specific SKU includes a built-in magnet (-S) for non-contact position detection using AirTAC CMSG reed or DMSG and EMSG solid-state sensor switches. End-of-stroke deceleration relies on a fixed rubber bumper, which softens impact without acting as an adjustable air cushion.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X175SU Is Used
Packaging Conveyor Diverter
Actuates a routing gate at 628N push force to redirect small cartons between packaging lanes without occupying excessive frame width.
PCB Test Socket Clamping
Utilizes the built-in magnet and DMSG solid-state sensor to confirm 175mm extension for securing delicate circuit boards during automated functional testing.
Textile Yarn Tensioner
Maintains precise dynamic tension on yarn guides using the 528N pull force, with the rigid U flat-end cover ensuring stable mounting on the loom frame.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X175SU the Right Cylinder?
Stepping down to the 32mm bore yields 402N of push force at 0.5 MPa, whereas stepping up to the 50mm bore provides 981N, allowing precise scaling for your load requirements. If your application demands faster cycling with heavier loads, the MBLC variant offers adjustable air cushioning to absorb kinetic energy. For simple push or pull operations without continuous air supply, consider the single-acting MSBL or MTBL models.
Because this 175mm stroke exceeds 300mm, the 16mm rod is susceptible to bending under lateral stress; utilize an external guide rail or select the MBLD double-rod anti-rotation type to manage side loads. Note that the fixed rubber bumper softens end-of-stroke impact but does not lock the rod; a standard MBL cylinder will drift and drop its load if air pressure is lost or the valve is centered. Use an external pilot-operated check valve if position holding is mandatory. Replacement matching requires a 40mm bore, 175mm stroke, G1/4 port, PT thread form, U flat-end back cover, and the -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 MBL40X175SU FAQ
At 0.5 MPa, this 40mm bore cylinder outputs 628N of push force and 528N of pull force. At 0.7 MPa, the push force increases to 880N, with a theoretical maximum of 128 kgf at 1.0 MPa. The operational speed ranges from 30-800 mm/s.
No, the base MBL40X175SU uses a fixed rubber bumper to soften end-of-stroke impact, which cannot be adjusted like a cushion screw. If your application requires adjustable air cushioning for heavier or faster moving loads, you must upgrade to the MBLC variant.
