The AirTAC AirTAC MBL63X225SU Mini Cylinder | 63mm Bore 225mm Stroke is a genuine double-acting aluminum-barrel mini round cylinder with a Ø63mm bore and 225mm 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 MBL63X225SU is a double-acting aluminum mini round cylinder engineered for heavy-duty clamping in spatially constrained machinery. Delivering a robust 1558 N of push force at 0.5 MPa, this 63 mm bore unit executes a 225 mm stroke via a Ø16 mm carbon-steel rod plated with 20 µm hard chrome for superior wear resistance. The riveted rolling-packed barrel keeps the overall footprint and weight to a minimum, making it far more compact than an ISO 15552 profile cylinder of equivalent power. This specific SKU features a U flat-end back cover for rigid fixed mounting and an integrated -S magnet for position detection.
Because this model includes the -S magnet, it directly supports AirTAC CMSG reed switches alongside DMSG and EMSG solid-state electronic sensors to confirm end-of-stroke positioning. Instead of an adjustable cushion, the base MBL relies on a fixed rubber bumper to soften end-of-stroke impacts. A heterogeneous two-way piston seal permanently retains internal grease, ensuring long-lasting lubrication even under high cyclic load.

Supplies the 1558 N push force needed to knock out heavy automotive plastic moldings, fitting neatly within the tight ejector plate cavities of standard molding presses.
Drives a 225 mm stroke routing mechanism to push heavy timber pallets onto a secondary packaging line, where the U flat-end back cover provides a rigid, zero-play mount.
Actuates a high-force bed-of-nails testing fixture for server motherboards, using the integrated -S magnet with a DMSG solid-state sensor to verify test head contact.
This 63 mm bore provides the maximum thrust available in the MBL family, yielding 318 kgf of theoretical force at 1.0 MPa. If your application does not require that much power, stepping down to the 50 mm bore drops the 0.5 MPa push force to 981 N while saving valuable mounting space. Since 63 mm is the largest available MBL size, there is no larger mini round option to step up to. For tasks needing softer end-of-stroke deceleration at these high forces, consider the MBLC variant which replaces the fixed rubber bumper with an adjustable air cushion.
With a 225 mm stroke driven by a Ø16 mm rod, the unsupported span is significant; mini cylinders have inherently low side-load tolerance, so an external guide rail is strongly recommended to prevent rod-bearing bending. Furthermore, this standard double-acting cylinder will not hold its load if air pressure is lost or the valve is centered—the rod will drift and drop. If gravitational load retention is required without live air pressure, install an external rod lock or a pilot-operated check valve. This SKU uses a G1/4 port with PT thread form, a U flat-end back cover, and includes the -S magnet.
Quick checklist
At 0.5 MPa it provides 1558 N push and 1457 N pull force. At 0.7 MPa push increases to 2181 N, with a theoretical maximum of 318 kgf at 1.0 MPa. The operating speed range is 30-800 mm/s.
No, the base MBL uses a fixed rubber bumper to absorb end-of-stroke impact, not an adjustable cushion screw. If your heavy 63 mm bore application requires adjustable pneumatic cushioning, you must switch to the MBLC variant.
