The AirTAC AirTAC MBL63X75SU Mini Cylinder | 63mm Bore 75mm is a genuine double-acting aluminum-barrel mini round cylinder with a Ø63mm bore and 75mm 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 MBL63X75SU is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces where high force is still required. Operating at 0.5 MPa, it delivers a push force of 1558 N and a pull force of 1457 N across its 75 mm stroke. This genuine pneumatic component features a built-in magnet for position detection.
Unlike tie-rod bodies, the MBL utilizes a riveted rolling-packed aluminum barrel where the covers are crimped to the tube, creating an exceptionally light yet durable housing that is not designed to be disassembled. The 16 mm carbon-steel piston rod is treated with 20 um hard-chrome plating for superior wear and corrosion resistance. This specific SKU includes an S suffix for a built-in magnet, allowing seamless integration with AirTAC CMSG (reed) or DMSG and EMSG (electronic) sensor switches to track rod position. The U flat-end back cover provides a rigid, fixed rear mounting surface.

Provides the robust 1558 N push force required to eject dense plastic parts from tight injection molding tooling spaces where larger profile cylinders cannot fit.
Drives a heavy-duty diverter arm on a packaging line, utilizing the 75 mm stroke and DMSG electronic sensors to rapidly sort dense parcels.
Secures thick printed circuit board assemblies during automated functional testing, applying precise 1457 N pull force via the rigid U flat-end mount.
Selecting this 63 mm bore cylinder makes sense when your application demands substantial thrust within a compact footprint. If you need to step down in force, the neighboring 50 mm bore offers 981 N of push force at 0.5 MPa. Conversely, if you require even more power, the 63 mm is the largest bore in the MBL mini round series, meaning you would need to transition to a larger profile cylinder like the SAI ISO 15552 line for higher capacity.
This model features a G1/4 port, an M14x1.5 rod-end thread, and a PT port thread form. Because the base MBL relies on a fixed rubber bumper rather than an adjustable air cushion, you should choose the MBLC variant if your system requires end-of-stroke speed tuning for heavier moving loads. Furthermore, a plain MBL does not hold its position or load when air pressure is lost or the valve is centered; the rod will drift or drop. If load holding is critical without live pressure, you must incorporate an external rod lock or a pilot-operated check valve into your circuit.
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 force of 318 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
No, the base MBL63X75SU uses a fixed rubber bumper to soften end-of-stroke impacts, not an adjustable air cushion or cushion screw. If your application requires adjustable end-of-stroke deceleration for heavier loads, you should select the MBLC variant.
