The AirTAC AirTAC MBL63X400SCA Mini Cylinder | 63mm Bore 400mm is a genuine double-acting aluminum-barrel mini round cylinder with a Ø63mm bore and 400mm 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 MBL63X400SCA is a double-acting aluminum mini round cylinder engineered for heavy-duty compact automation. Delivering a robust 1558 N push force at 0.5 MPa (and up to 318 kgf at 1.0 MPa), this 63 mm bore, 400 mm stroke unit excels in demanding tight-space machinery. The riveted rolling-packed aluminum barrel keeps the body light and small, though it is not designed to be disassembled and rebuilt like a tie-rod cylinder.
This specific SKU includes a built-in magnet (-S) for compatibility with AirTAC CMSG reed and DMSG or EMSG electronic sensor switches to track rod position. It features a CA pivot back cover that swings on a pin to accommodate arcing and angular loads. End-of-stroke impact is absorbed by a fixed rubber bumper rather than an adjustable air cushion.

Drives the 400 mm reach of a secondary robotic pick arm in packaging lines, utilizing the 1558 N push force to lift dense product trays.
Actuates a heavy pivot gate on a parcel conveyor, where the CA clevis back cover absorbs the angular load as the 400 mm rod deflects packages.
Ejects loaded pallets from a compact wrapping cell, relying on the 318 kgf maximum force and the DMSG sensor to confirm full ejection.
For lower force needs in compact spaces, step down to the 50 mm bore, which provides 981 N push at 0.5 MPa. If you require even greater thrust, note that 63 mm is the largest available bore in this mini series. If your application demands faster cycling with heavier loads, consider the MBLC variant, which offers adjustable air cushioning to tame end-of-stroke kinetic energy.
Because this is a 400 mm stroke, the unsupported Ø16 mm carbon-steel rod is highly susceptible to side-load bending; the CA pivot back cover is essential here to prevent rod-bearing damage. Remember that a plain MBL does not hold its load when air pressure is lost or exhausted—the rod will drift. For safety, install an external pilot-operated check valve or a dedicated rod lock. Replacement match: 63 mm bore, 400 mm stroke, G1/4 port, PT thread, CA pivot cover, magnet included.
Quick checklist
At 0.5 MPa it provides 1558 N push and 1457 N pull. At 0.7 MPa push increases to 2181 N. The maximum theoretical force is 318 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa.
No, the base MBL uses a fixed rubber bumper to soften end-of-stroke impact. For adjustable air cushioning, you must select the MBLC variant. This SKU does include a magnet for CMSG, DMSG, or EMSG sensor switches.
