The AirTAC AirTAC MBL63X25U Mini Cylinder | 63mm Bore 25mm Stroke 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 MBL63X25U is a compact double-acting aluminum mini round cylinder engineered to deliver substantial thrust in tight machine spaces. Operating at 0.5 MPa, it generates 1558 N of push force and 1457 N of pull force, making this 25 mm stroke variant well-suited for heavy-duty clamping or short ejection tasks. The U suffix denotes a rigid flat-end back cover, providing a solid fixed-mount rear footprint for straightforward integration.
Unlike tie-rod bodies, this unit features a riveted rolling-packed barrel that crimps the covers to the tube, ensuring a lightweight yet permanently sealed assembly. The carbon-steel piston rod is hardened with 20 um chrome plating to resist wear and corrosion, while a heterogeneous two-way piston seal retains grease for a long service life. Note that this specific SKU lacks the -S suffix, so it cannot accept a CMSG, DMSG, or EMSG position sensor switch.

Related variants: MBLC (adjustable cushion), MBLD (double rod), MBLJ (adjustable stroke), MSBL/MTBL (single acting).
Provides 1558 N of push force to eject dense plastic parts from tight mold cavities where a larger profile cylinder would exceed the machine footprint.
Acts as a robust diverter arm on packaging lines, using its 25 mm stroke to quickly push heavy cartons onto a secondary belt without occupying valuable floor space.
Delivers up to 318 kgf of clamping force at 1.0 MPa for pressing small bearings or pins into housings within compact bench-top assembly jigs.
As the largest standard bore in the MBL family, stepping down means choosing the 50 mm bore, which yields 981 N of push force at 0.5 MPa. If your application requires even more power, you must switch to a larger ISO 15552 profile cylinder like the AirTAC SAI series. The base MBL uses a fixed rubber bumper to soften end-of-stroke impact; for faster cycling or heavier moving masses, upgrade to the MBLC variant which features an adjustable air cushion.
When ordering a replacement, verify the 63 mm bore, 25 mm stroke, G1/4 port size, PT tapered thread form, and the U flat-end back cover. Keep in mind that a plain double-acting cylinder drifts when air pressure is removed or exhausted; this rubber bumper is not a brake. If the load must be held without live pressure, install an external pilot-operated check valve or a dedicated rod lock.
Quick checklist
At 0.5 MPa, this 63 mm bore cylinder provides 1558 N of push force and 1457 N of pull force. At 0.7 MPa, the push force increases to 2181 N, with a theoretical maximum of 318 kgf at 1.0 MPa. It operates at a speed range of 30-800 mm/s.
No, because this specific SKU lacks the -S suffix, it has no built-in magnet and cannot accept CMSG, DMSG, or EMSG sensor switches. To use solid-state or reed switches for rod position detection, you must order the MBL63X25SU variant.
