About the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X75U
The AirTAC MBL25X75U is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. Operating at 0.5 MPa, it provides 245 N of push force and 206 N of pull force over a 75 mm stroke, making it well-suited for short-distance positioning tasks. Its small footprint and lightweight riveted barrel design allow it to fit where larger ISO 15552 profile cylinders cannot.
This specific SKU features a U flat-end back cover for rigid, fixed mounting. The piston utilizes a heterogeneous two-way seal that retains grease for long service life, while the carbon steel rod features 20 um hard-chrome plating to resist wear and corrosion. Because this configuration lacks the -S suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor. The base MBL relies on a fixed rubber bumper to soften end-of-stroke impacts rather than an adjustable air cushion.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X75U Is Used
PCB Routing Station
Provides 245 N of push force at 0.5 MPa to actuate a routing gate on a printed circuit board assembly line, fitting neatly within the dense 75 mm stroke envelope.
Carton Flap Folder
Drives a compact folding arm to tuck minor flaps on small packaging boxes, utilizing its rigid U flat-end rear mount to maintain precise alignment without arcing.
Lab Tube Ejector
Pushes capped test tubes out of a sorting carousel using its 75 mm stroke, where the fixed rubber bumper adequately absorbs the light impact without needing adjustment.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X75U the Right Cylinder?
When sizing this 25 mm bore actuator, consider stepping down to the 20 mm bore if your application requires less than 157 N of push force at 0.5 MPa, or moving up to the 32 mm bore if you need a higher output of 402 N. If your cycle speed creates severe end-of-stroke shock, the MBLC variant offers an adjustable air cushion to absorb heavier kinetic energy. For tasks requiring the rod to stay put after a valve centers or air pressure drops, note that the fixed rubber bumper on this standard MBL is not a locking device; you will need an external pilot-operated check valve or rod lock to hold a suspended load. This exact replacement match features a 25 mm bore, 75 mm stroke, G1/8 port size, PT thread form, U flat-end back cover, and no built-in 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 MBL25X75U FAQ
This 25 mm bore cylinder delivers 245 N push and 206 N pull at 0.5 MPa, and 343 N push at 0.7 MPa, with a theoretical maximum force of 50 kgf at 1.0 MPa. It operates at speeds between 30-800 mm/s within a 0.15-1.0 MPa pressure range.
No, because this specific SKU lacks the -S suffix for a built-in magnet, it cannot accept CMSG, DMSG, or EMSG sensor switches. If electronic or reed position detection is required, you must select the MBL25X75SU variant.
