The AirTAC AirTAC MBL63X25SCA Mini Cylinder | 63mm Bore 25mm is a genuine double-acting aluminum-barrel mini round cylinder with a Ø63mm bore and 25mm stroke, G1/4 air ports and a fixed rubber bumper. Its compact riveted body suits push, hold and clamp motion in tight machine spaces.
The AirTAC MBL63X25SCA is a double-acting aluminum mini round cylinder engineered for high-force actuation in constrained machine footprints. Operating at 0.5 MPa, it generates 1558 N of push force and 1457 N of pull force across its 25 mm stroke, making it highly effective for short, powerful clamping or ejecting tasks. The cylinder features a G1/4 port and a robust Ø16 mm carbon steel piston rod plated with 20 µm hard chrome for superior wear and corrosion resistance.
This specific SKU includes a built-in magnet (-S) for compatibility with AirTAC CMSG, DMSG, and EMSG sensor switches to confirm end-of-stroke positioning. It is fitted with a CA pivot back cover, allowing the body to swing on a pin to safely absorb angular arcing loads. The riveted rolling-packed barrel keeps the assembly lightweight and compact, while the internal fixed rubber bumper softens end-of-stroke impacts without acting as a position lock. For applications needing adjustable end-cushioning to dissipate higher kinetic energy, the MBLC variant is recommended.

Uses the 1558 N push force at 0.5 MPa to reliably knock heavy metal stampings out of a die in a confined press bed.
The CA pivot back cover allows the cylinder to swing a heavy diverter arm on packaging conveyor lines, absorbing angular side loads.
Provides the high push force needed to fold thick cardboard flaps on high-speed beverage packaging lines where space is highly restricted.
Choosing this 63 mm bore provides 1558 N of thrust at 0.5 MPa, which is ideal when the next size down (50 mm bore, 981 N push) lacks the necessary power for heavy pressing. If your application requires less force and a smaller physical envelope, stepping down to the 50 mm bore is advised. Conversely, if your machine layout cannot accommodate the 63 mm body diameter, dropping to the 50 mm size is the only viable option, as 63 mm is the largest standard bore in the MBL series.
The CA pivot back cover is explicitly designed for arcing or pivotal movements, pairing well with an SDB pivot bracket. Because the base MBL uses a fixed rubber bumper rather than an adjustable air cushion, heavier or faster moving loads should be upgraded to the MBLC variant. Furthermore, a plain MBL cannot hold a load if air pressure is lost or exhausted; the rod will drift. If position holding is critical without live air pressure, incorporate an external pilot-operated check valve or a dedicated rod lock.
Quick checklist
At 0.5 MPa, the push force is 1558 N and the pull force is 1457 N. At 0.7 MPa, the push force increases to 2181 N. The maximum theoretical force is 318 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa.
Yes, the -S suffix indicates a built-in magnet, allowing you to mount AirTAC CMSG (reed), DMSG, or EMSG (electronic) sensor switches directly to the body for position detection. For cushioning, the base MBL uses a fixed rubber bumper to soften end-of-stroke impacts; it is not an adjustable air cushion. If you need adjustable cushioning for heavier loads, choose the MBLC variant.
