The AirTAC Airtac MBL Aluminum Alloy Mini Cylinder MBL25X800SU is a genuine double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 800mm stroke, 1/8" air ports and a fixed rubber bumper. Its compact riveted body suits push, hold and clamp motion in tight machine spaces.
The AirTAC MBL25X800SU is a compact double-acting aluminum mini round cylinder engineered for an exceptionally long 800mm stroke. This made-to-order stroke exceeds the standard 500mm limit, providing 245N of push force and 206N of pull force at 0.5 MPa. It is built with a riveted rolling-packed barrel where the front and back covers are crimped to the tube, ensuring a lightweight footprint for tight machine spaces. The U flat-end back cover provides a rigid, fixed rear mounting surface for straightforward installation.
Because this SKU includes the -S suffix, it contains a built-in magnet for non-contact position detection using AirTAC CMSG (reed), DMSG, or EMSG (electronic solid-state) sensor switches. The piston relies on a heterogeneous two-way seal that retains grease for long service life, while the Ø10mm carbon steel rod features 20µm hard-chrome plating to resist wear and corrosion. The base MBL design utilizes a fixed rubber bumper to soften end-of-stroke impacts rather than an adjustable air cushion.

Uses the full 800mm stroke to push lightweight cartons across a wide diverter gap on a packaging line, relying on the 245N push force to overcome box friction.
Extends fully to shift a textile beam into a loading cradle where space constraints favor the compact aluminum riveted body over a larger profile cylinder.
Moves large printed circuit board panels down a long linear path, using the -S magnet and a DMSG electronic sensor to confirm full extension.
This 25mm bore cylinder provides 245N push force at 0.5 MPa. If your application requires less force, stepping down to the 20mm bore yields 157N of push force. If you need more power, stepping up to the 32mm bore provides 402N. For this specific 800mm stroke, the Ø10mm piston rod is highly susceptible to bending under side loads; an external guide rail or a pivot mounting accessory is strongly recommended to prevent rod-bearing damage. If end-of-stroke speeds are high, consider the MBLC variant which adds an adjustable air cushion to absorb kinetic energy better than the standard fixed rubber bumper.
A plain MBL cylinder does not hold its position or load when air pressure is lost or the valve is centered, as the rod will drift or drop. The rubber bumper only softens the impact and is not a locking mechanism. If the load must be held without live pressure, an external rod lock or pilot-operated check valve is required. This exact replacement configuration features a 25mm bore, 800mm stroke, G1/8 port size, PT thread form, U flat-end back cover, no mounting accessory, and a built-in magnet (-S).
Quick checklist
At 0.5 MPa, this 25mm bore cylinder provides 245N of push force and 206N of pull force. At 0.7 MPa, the push force increases to 343N, with a theoretical maximum of 50 kgf at 1.0 MPa. The operating speed ranges from 30-800 mm/s.
The base MBL uses a fixed rubber bumper to soften the end-of-stroke impact; it does not have an adjustable cushion screw. If your 800mm stroke results in heavy end-of-stroke kinetic energy, stepping up to the MBLC variant provides an adjustable air cushion to better absorb the shock.
