About the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X225SU
The AirTAC MBL32X225SU is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces where a larger profile body cannot fit. Operating at 0.5 MPa, it generates 402 N of push force and 346 N of pull force, making it well-suited for mid-range stroke tasks requiring a 225 mm extension. The U flat-end back cover provides a rigid, fixed rear mounting surface for secure attachment.
Unlike tie-rod cylinders, this unit features a riveted rolling-packed barrel that cannot be disassembled for rebuilding, ensuring a permanently sealed, lightweight profile. End-of-stroke deceleration relies on a fixed rubber bumper rather than an adjustable cushion. Because this SKU includes the -S suffix, it has a built-in magnet compatible with AirTAC CMSG (reed), DMSG, and EMSG (solid-state) sensor switches for non-contact rod position detection.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X225SU Is Used
Spindle Load/Unload
Drives a 225 mm stroke to push raw bar stock into a lathe collet, utilizing its 402 N push force at 0.5 MPa to overcome chuck insertion resistance.
Pallet Diverter Arm
Extends a narrow profile diverter flap between conveyor rollers, using the U flat-end cover for rigid mounting and the -S magnet to confirm stroke completion.
Packaging Flap Folder
Folds cardboard carton flaps at high speed, where the fixed rubber bumper absorbs the mechanical end-of-stroke impact without requiring adjustment.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X225SU the Right Cylinder?
When sizing this actuator, consider stepping down to the MBL25 bore if your load requires less than 245 N of push force at 0.5 MPa, or stepping up to the MBL40 bore if you need greater thrust (628 N push at 0.5 MPa). If your application demands softer end-of-stroke deceleration for faster cycling, select the MBLC variant which features an adjustable air cushion instead of the standard fixed rubber bumper.
The 225 mm stroke on this Ø12 mm piston rod creates an unsupported length that is highly susceptible to bending under side loads. To prevent premature rod-bearing wear, use an external guide rail, pair the cylinder with a pivot mount, or switch to the MBLD double-rod anti-rotation type. Note that a standard MBL cannot hold a load if air pressure is lost or exhausted; the rubber bumper softens impact but does not lock the rod. Use an external pilot-operated check valve if position holding is required. Replacement requires matching the 32 mm bore, 225 mm stroke, G1/8 port, PT thread, U flat-end cover, and -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 MBL32X225SU FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 346 N of pull force. At 0.7 MPa, the push force increases to 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa.
The base MBL32X225SU uses a fixed rubber bumper and does not have an adjustable cushion screw; for adjustable air cushioning, you must switch to the MBLC variant. This specific SKU includes a built-in magnet (-S) designed to work with AirTAC CMSG (reed), DMSG, and EMSG (electronic) sensor switches for position detection.
