The AirTAC AirTAC MBL63X20CA Mini Cylinder | 63mm Bore 20mm Stroke is a genuine double-acting aluminum-barrel mini round cylinder with a Ø63mm bore and 20mm 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 MBL63X20CA is a double-acting aluminum mini round cylinder engineered for tight machine spaces where high force is needed. Operating at 0.5 MPa, it generates 1558 N of push force and 1457 N of pull force. The short 20 mm stroke is ideal for high-impact pressing or short clamping duties. This specific SKU features a CA back cover, meaning it is a pivot or clevis type that swings on a pin to accommodate arcing or angular loads during movement.
Unlike tie-rod cylinders, this unit uses a riveted rolling-packed aluminum barrel where the front and rear covers are crimped to the tube, making it exceptionally light but not designed to be disassembled. The Ø16 mm carbon-steel piston rod features 20 um hard-chrome plating for high wear and corrosion resistance. Because this specific code lacks the -S suffix, it has no built-in magnet and cannot support a CMSG, DMSG, or EMSG position sensor.

Uses the 1558 N push force at 0.5 MPa to knock stamped small metal parts out of a progressive die in a confined mechanical press setup.
Provides 1457 N of pull force to hold a PCB panel securely against a fixture while a router bit cuts individual circuit boards.
Leverages the CA pivot back cover to swing a short diverter gate on a packaging conveyor, accommodating the arcing load path.
If you need slightly less force, the MBL50 bore offers 981 N push at 0.5 MPa; if you need more, the 63 mm bore here is the largest available in the MBL series. For applications requiring end-of-stroke deceleration for heavier moving masses, step up to the MBLC variant which features an adjustable air cushion instead of this model's fixed rubber bumper. If you need a spring-return function, consider the MSBL or MTBL single-acting versions (available in 20-40 mm bores).
Replacement parts must match the 63 mm bore, 20 mm stroke, G1/4 port size, PT thread form, and CA pivot back cover. Note that a plain MBL does not hold its position or load when air pressure is lost or the valve is centred, as the rod will drift. The rubber bumper only softens end-of-stroke impact and is not a locking brake.
Quick checklist
At 0.5 MPa, the MBL63X20CA generates 1558 N of push force and 1457 N of pull force. At 0.7 MPa, the push force increases to 2181 N. The maximum theoretical force is 318 kgf at 1.0 MPa.
This base MBL model uses a fixed rubber bumper to soften end-of-stroke impact and does not have an adjustable cushion screw (you would need the MBLC variant for adjustable air cushioning). Additionally, because this SKU lacks the -S suffix for a built-in magnet, you cannot mount a CMSG, DMSG, or EMSG sensor switch to detect rod position.
