The AirTAC AirTAC MBL63X25CA Mini Cylinder | 63mm Bore 25mm Stroke is a genuine double-acting aluminum-barrel mini round cylinder with a Ø63mm bore and 25mm 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 MBL63X25CA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces where high thrust is required. Operating at 0.5 MPa, it delivers 1558 N of push force and 1457 N of pull force across its 25 mm stroke. The 63 mm bore is paired with a G1/4 port and a robust Ø16 mm carbon steel rod plated with 20 µm hard chrome for superior wear and corrosion resistance.
This specific SKU features a CA pivot (clevis) back cover, allowing the cylinder body to swing freely on a pin to accommodate arcing or angular loads during operation. Unlike tie-rod bodies, the MBL uses a riveted rolling-packed aluminum barrel that is permanently crimped to the front and rear covers, minimizing weight and footprint. Note that because this configuration lacks the -S suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor. End-of-stroke deceleration is handled by a fixed rubber bumper, not an adjustable cushion screw.

Delivers 1558 N of push force at 0.5 MPa to seat bearings or pins into housings on automated machining lines without requiring a full-size profile cylinder.
The CA clevis back cover swings smoothly on a mounting pin, making it ideal for actuating a heavy diverter gate that must follow an arcing path across a packaging conveyor.
Uses 1457 N of retraction force to pull a heavy stopper blade out of the way on a roller conveyor, freeing up valuable space within the tight frame envelope.
Selecting this 63 mm bore model makes sense when your application requires substantial force in a compact envelope. If you need to step down, the 50 mm bore neighbor provides 981 N of push force at 0.5 MPa, which may suffice for lighter duties. Stepping up is not possible within the MBL range as 63 mm is the largest available bore; for even greater thrust, an ISO 15552 profile cylinder like the AirTAC SAI series would be required. Keep in mind the base MBL does not hold its position if air pressure is lost; the rod will drift. Use an external pilot-operated check valve if load holding is critical. For applications needing faster cycle speeds with heavier masses, consider the MBLC variant, which replaces the fixed rubber bumper with an adjustable air cushion.
Quick checklist
This 63 mm bore cylinder uses a Ø16 mm rod with an M14x1.5 rod-end thread and a G1/4 port. At 0.5 MPa it outputs 1558 N push and 1457 N pull. At 0.7 MPa the push force increases to 2181 N, and the maximum theoretical force is 318 kgf at 1.0 MPa.
This specific SKU does not have the -S magnet suffix, so it cannot accept CMSG, DMSG, or EMSG electronic or reed sensor switches. Additionally, the base MBL uses a fixed rubber bumper for end-of-stroke impact absorption rather than an adjustable cushion; if you need adjustable air cushioning, look at the MBLC variant.
