The AirTAC AirTAC MBL63X450SU Mini Cylinder | 63mm Bore 450mm is a genuine double-acting aluminum-barrel mini round cylinder with a Ø63mm bore and 450mm 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 MBL63X450SU is a double-acting aluminum mini round cylinder engineered for heavy-duty clamping and lifting in confined machinery. Delivering 1558 N of push force at 0.5 MPa and 2181 N at 0.7 MPa, this 63 mm bore unit manages substantial loads over its 450 mm stroke. The U flat-end back cover provides a rigid fixed rear mounting for straight-line thrust, while the built-in -S magnet enables CMSG, DMSG, or EMSG sensor switches to track rod position.
Unlike tie-rod bodies, the MBL uses a riveted rolling-packed aluminum barrel that is permanently crimped at the factory, ensuring a lightweight, compact footprint that resists pneumatic leaks. The carbon steel piston rod features a 20 um hard-chrome plating for wear resistance, paired with a heterogeneous two-way piston seal that retains grease for extended operational life. End-of-stroke deceleration relies on a fixed rubber bumper rather than an adjustable cushion.

Provides 1558 N of push force to eject dense plastic parts from tight mold cavities where a larger ISO cylinder cannot fit.
Utilizes the 450 mm stroke and built-in magnet to actuate a heavy diverter gate on a packaging line, confirming arm position via DMSG sensors.
Deploys a rigid U flat-end stop block to arrest heavy 318 kgf loaded pallets on a low-profile gravity roller conveyor.
This 63 mm bore generates 1558 N push and 1457 N pull at 0.5 MPa. If your assembly requires less force, the 50 mm bore offers 981 N push, whereas stepping up is not possible as 63 mm is the largest MBL size. For applications needing softer end-of-stroke deceleration at these high forces, select the MBLC variant which features an adjustable air cushion instead of the standard fixed rubber bumper.
With a 450 mm stroke, the Ø16 mm rod is highly susceptible to bending under side loads; an external guide rail or pivot mount is strongly recommended to prevent premature seal wear. Additionally, this plain double-acting cylinder will drift and drop its load if air pressure is lost or the valve is centered, as the rubber bumper is not a locking brake. Use an external pilot-operated check valve if position holding is required.
Quick checklist
This 63 mm bore cylinder provides 1558 N push and 1457 N pull at 0.5 MPa, 2181 N push at 0.7 MPa, and a maximum theoretical force of 318 kgf at 1.0 MPa. It uses a G1/4 port with a PT thread form, a Ø16 mm rod, and an M14x1.5 rod-end thread.
No, the base MBL63X450SU uses a fixed rubber bumper to soften end-of-stroke impacts and cannot be adjusted. If your application requires tunable cushioning for heavier moving masses, you must switch to the AirTAC MBLC variant which features an adjustable air cushion.
