About the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X175SU
The AirTAC MBL25X175SU is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers 245 N of push force and 206 N of pull force at 0.5 MPa, making it well-suited for 175 mm linear positioning tasks in light assembly machinery. The riveted rolling-packed barrel permanently crimps the front and rear covers to the tube, yielding a lightweight footprint that is not designed to be disassembled like a tie-rod cylinder. This SKU includes a built-in magnet (-S) for rod position detection and a U flat-end back cover for rigid fixed mounting.
Inside, a heterogeneous two-way piston seal retains grease for long service life, while the Ø10 mm carbon-steel piston rod features 20 μm hard-chrome plating to resist wear and corrosion. The base MBL relies on a fixed rubber bumper to soften end-of-stroke impact rather than an adjustable air cushion. Because the U back cover provides a rigid rear mount, it is ideal for straightforward in-line pushing rather than arcing or angular loads.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X175SU Is Used
PCB Shuttle Conveyance
Drives a 175 mm shuttle stroke for pushing bare PCBs between inspection stations, utilizing the 245 N push force to overcome carrier friction without overwhelming delicate electronic assemblies.
Carton Flap Folding
Executes a 175 mm stroke to fold minor carton flaps on a continuous packaging line, where the compact aluminum body fits into tight transfer gaps between conveyor belts.
Lab Tube Ejection
Pushes centrifuge tube racks out of a centrifuge housing using the 206 N pull force for safe retraction, while the -S magnet triggers a DMSG electronic sensor to confirm rack clearance.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X175SU the Right Cylinder?
If you need less force, step down to the MBL20X175SU, which provides 157 N push at 0.5 MPa. If your application requires more thrust, step up to the MBL32X175SU, which delivers 402 N push at 0.5 MPa. For faster or heavier moves where end-of-stroke impact is a concern, select the MBLC variant, which replaces the fixed rubber bumper with an adjustable air cushion. If you need a spring-return function rather than double-acting air control, consider the MSBL (push) or MTBL (pull) single-acting variants.
At 175 mm of stroke, the Ø10 mm rod has a relatively low side-load tolerance. To prevent rod-bearing bending under offset loads, use an external guide rail, switch to a CA pivot back cover for arcing motions, or choose the MBLD double-rod cylinder for anti-rotation support. Note that this plain MBL cylinder does not hold its position or load when air pressure is lost, exhausted, or the valve is centred; the rod drifts or drops. Use an external rod lock or a pilot-operated check valve if the load must be held without live pressure. This SKU features a G1/8 port, PT thread form, U flat-end back cover, and a built-in magnet (-S) compatible with CMSG, DMSG, and EMSG sensor switches.

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 MBL25X175SU FAQ
This 25 mm bore cylinder provides a push force of 245 N and a pull force of 206 N at 0.5 MPa. At 0.7 MPa, the push force increases to 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa.
The base MBL uses a fixed rubber bumper to soften end-of-stroke impact and does not have an adjustable cushion screw; for adjustable air cushioning, you need the MBLC variant. This specific MBL25X175SU model includes a built-in magnet (-S), allowing you to mount AirTAC CMSG (reed), DMSG, or EMSG (electronic) sensor switches directly on the body for rod position detection.
