The AirTAC AirTAC MBL63X250CA Mini Cylinder | 63mm Bore 250mm is a genuine double-acting aluminum-barrel mini round cylinder with a Ø63mm bore and 250mm 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 MBL63X250CA is a double-acting aluminum mini round cylinder engineered for heavy-duty clamping in confined machinery spaces. Operating at 0.5 MPa, it delivers a substantial 1558 N of push force and 1457 N of pull force, scaling up to a maximum theoretical output of 318 kgf at 1.0 MPa. The 250 mm stroke provides ample travel for deep-reaching actuators, while the G1/4 port and Ø16 carbon-steel rod handle the high airflow and structural demands of this 63 mm bore class.
This specific SKU features a CA pivot back cover that swings on a pin to accommodate arcing or angular loads, distinguishing it from rigid flat-end U models. The body utilizes a riveted rolling-packed aluminum barrel that cannot be disassembled for rebuilds, ensuring a permanently compact footprint. End-of-stroke deceleration relies on a fixed rubber bumper rather than an adjustable cushion. Note that because this configuration lacks the -S suffix, a position sensor cannot be fitted to this cylinder.

Drives a 250 mm reaching arm to eject heavy molded plastic parts from deep cavities, utilizing the 1558 N push force to overcome ejection friction.
Uses the CA pivot back cover to swing a diverter blade across a conveyor line, absorbing angular momentum while routing heavy pallets.
Applies 1457 N of pull force to seat large edge connectors onto printed circuit boards within a compact electronics assembly fixture.
Selecting this 63 mm bore provides 1558 N of thrust at 0.5 MPa; if your fixture requires less force, stepping down to the 50 mm bore yields 981 N of push, whereas moving up is unnecessary as 63 mm is the largest standard MBL size. For applications needing single-direction spring return, consider the MSBL or MTBL single-acting variants (available in 20-40 mm bores). If your machine cycle demands precise end-of-stroke deceleration for heavier moving masses, upgrade to the MBLC variant which replaces the fixed rubber bumper with an adjustable air cushion.
Because this model features a 250 mm stroke, the unsupported Ø16 rod is highly susceptible to bending under side loads—pairing the CA pivot cover with an external guide rail or switching to an MBLD double-rod cylinder is strongly recommended to prevent premature seal wear. Additionally, this cylinder cannot hold its load if air pressure is lost; the rubber bumper only softens end impacts and acts as no brake, so integrate an external pilot-operated check valve if gravity or drift poses a hazard. This SKU uses a PT port thread, M14x1.5 rod-end thread, and no magnet.
Quick checklist
At 0.5 MPa, this 63 mm bore cylinder provides 1558 N of push force and 1457 N of pull force. When operating at 0.7 MPa, the push force increases to 2181 N. The absolute maximum theoretical force is 318 kgf when pressurized to 1.0 MPa.
No, this specific SKU lacks the -S suffix, meaning no internal magnet is present and CMSG, DMSG, or EMSG sensor switches cannot be fitted. Additionally, it uses a fixed rubber bumper for end-of-stroke impact absorption; for adjustable air cushioning, you must specify the MBLC variant.
