The AirTAC AirTAC MBL63X175U Mini Cylinder | 63mm Bore 175mm is a genuine double-acting aluminum-barrel mini round cylinder with a Ø63mm bore and 175mm 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 MBL63X175U is a double-acting aluminum mini round cylinder engineered for high-force output within a compact footprint. It generates 1558 N of push force and 1457 N of pull force at 0.5 MPa, making it well-suited for moving heavy jigs or actuating robust clamps over its 175 mm stroke. The U suffix designates a flat-end rigid back cover for straightforward fixed mounting. As a genuine AirTAC component, it features a riveted rolling-packed barrel that crimps the covers to the tube, ensuring a lightweight yet durable assembly that is not designed to be disassembled like a tie-rod cylinder.
This SKU lacks the -S magnet suffix, meaning it cannot accept a CMSG, DMSG, or EMSG position sensor switch. To handle end-of-stroke impacts, the base MBL relies on a fixed rubber bumper rather than an adjustable air cushion. Internal longevity is supported by a heterogeneous two-way piston seal that retains grease, paired with a carbon-steel piston rod plated with 20 µm of hard chrome to resist wear and corrosion.

Provides the 1558 N push force at 0.5 MPa needed to eject heavy plastic parts from stationary injection mold tooling, utilizing the 175 mm stroke to clear the mold cavity fully.
Drives a heavy mechanical diverter arm on a packaging conveyor, where the flat-end U back cover mounts rigidly to the machine frame to redirect loaded pallets.
Actuates a gripper slide to feed sheet metal blanks into a small stamping press, relying on the high 318 kgf maximum theoretical force to overcome mechanical friction.
At 63 mm, this bore provides the maximum standard thrust in the MBL family (318 kgf at 1.0 MPa). If your application requires less force, stepping down to the 50 mm bore yields 981 N of push at 0.5 MPa, which may suffice for lighter loads. Because 63 mm is the largest standard MBL bore, there is no larger step-up within this mini series. If you need faster cycling with heavy loads, consider the MBLC variant, which adds an adjustable air cushion to absorb kinetic energy more effectively than the fixed rubber bumper.
With a 175 mm stroke, the Ø16 mm piston rod is unsupported for a significant distance, making it highly susceptible to bending under side loads. To prevent premature seal failure, use an external guide rail or pivot the load. Remember that a plain double-acting MBL does not hold its position if air pressure is lost or the valve is centered; the rod will drift. For safety-critical drop loads, install an external pilot-operated check valve or a dedicated rod lock. Replacement parts must match the 63 mm bore, 175 mm stroke, G1/4 port, PT thread, and U flat-end back cover.
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. The maximum theoretical force is 318 kgf at 1.0 MPa. The operating speed ranges from 30-800 mm/s.
No. Because this SKU lacks the -S suffix, it has no built-in magnet and cannot accept CMSG, DMSG, or EMSG sensor switches. Additionally, the base MBL uses a fixed rubber bumper to soften end-of-stroke impacts; it does not have an adjustable cushion screw. If you need adjustable end-cushioning, choose the MBLC variant.
