The AirTAC AirTAC MBL63X150SU Mini Cylinder | 63mm Bore 150mm Stroke is a genuine double-acting aluminum-barrel mini round cylinder with a Ø63mm bore and 150mm 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 MBL63X150SU is a double-acting aluminum mini round cylinder engineered for tight machinery spaces where high thrust is still required. At 0.5 MPa it generates 1558 N of push force and 1457 N of pull force, making this 150 mm stroke variant well-suited for moving heavy jigs or robust clamping arms. The riveted rolling-packed barrel crimps the front and rear covers directly to the tube, yielding a lightweight, compact body that is not designed to be disassembled like a traditional tie-rod cylinder.
This specific SKU includes a U flat-end back cover for rigid rear mounting and a built-in magnet (-S) for non-contact position detection. The Ø16 mm carbon-steel piston rod features 20 um hard-chrome plating for wear resistance, while a heterogeneous two-way piston seal retains grease for a long service life. It operates at 30-800 mm/s and uses a G1/4 port with an M14x1.5 rod-end thread.

Provides the 1558 N push force needed to eject dense plastic parts from tight mold cavities, while the built-in magnet confirms full ejection stroke to the PLC.
Drives a heavy mechanical diverter gate on a packaging conveyor where the 150 mm stroke provides sufficient travel to redirect filled boxes.
Secures thick, multi-layer PCB test fixtures with 1457 N of pull force, using the rigid U flat-end mount to maintain perpendicular clamping pressure.
This 63 mm bore provides the highest standard thrust in the MBL family, delivering 1558 N push at 0.5 MPa. If your application requires less force, step down to the 50 mm bore, which offers 981 N of push force. As the largest available size, there is no larger standard MBL option for higher loads. The base MBL uses a fixed rubber bumper to soften end-of-stroke impact; if your machine needs adjustable air cushioning for heavier moving masses, select the MBLC variant instead.
Because the U flat-end cover mounts rigidly, lateral misalignment will stress the rod bearing. For this 150 mm stroke, ensure an external linear guide supports the load to prevent rod bending. Note that a plain MBL cannot hold a load if air pressure drops—the rod will drift. Use an external pilot-operated check valve for position holding. This configuration uses a PT tapered port thread, a U flat-end back cover, and a -S magnet compatible with CMSG (reed) and DMSG/EMSG (electronic) switches.
Quick checklist
This double-acting 63 mm bore cylinder generates 1558 N push and 1457 N pull at 0.5 MPa, and 2181 N push at 0.7 MPa, with a maximum theoretical force of 318 kgf at 1.0 MPa. It operates at 30-800 mm/s, uses a G1/4 port, and accepts a pressure range of 0.15-1.0 MPa.
No, the base MBL uses a fixed rubber bumper to absorb impact at the end of the stroke, not an adjustable cushion screw. If your application moves heavy loads at high speeds and requires adjustable pneumatic cushioning, you should select the MBLC variant instead.
