About the Airtac MBL Aluminum Alloy Mini Cylinder MBL50X25-CA
The AirTAC MBL50X25-CA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces where a larger profile body will not fit. It delivers a robust 981 N push force at 0.5 MPa, making this 50mm bore, 25mm stroke unit ideal for short, heavy-duty positioning tasks. The riveted rolling-packed barrel crimps the front and rear covers directly to the tube, ensuring a lightweight, space-saving assembly that is permanently sealed rather than designed for teardown like a tie-rod cylinder.
This specific SKU features a CA pivot back cover, allowing the cylinder body to swing on a fixed pin to absorb arcing or angular loads during motion. Because it lacks the -S suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor. The carbon-steel piston rod is hardened with a 20 um chrome plating for high wear resistance, and the internal heterogeneous two-way piston seal actively retains grease for a long, maintenance-free service life.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL50X25-CA Is Used
Packaging Diverter Arm
Drives a short 25mm stroke pivot arm to route heavy sealed cartons on a packaging conveyor, utilizing the 981 N push force and CA clevis to accommodate the arc of the swinging mechanism.
Injection Mold Ejection
Pushes a localized ejector pin plate out of a tight injection mold cavity, where the compact aluminum body fits within the press platen and the 1374 N force at 0.7 MPa breaks the part loose.
Pallet Lift Gate
Actuates a short pivot gate to lower heavy product totes from a roller conveyor into a palletizing cell, relying on the CA pivot mount to handle the side-loading as the gate rotates.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL50X25-CA the Right Cylinder?
If you need slightly less force, the 40mm bore neighbor provides 628 N push at 0.5 MPa; stepping up to the 63mm bore yields 1558 N for heavier loads. The CA clevis mount is optimal here for angular articulation, but if your load requires holding without live air pressure, note that the fixed rubber bumper only softens end-of-stroke impact—it is not a lock. You must add an external rod lock or pilot-operated check valve to prevent drift. For faster cycle speeds with heavier masses, consider the MBLC variant which adds an adjustable air cushion. This SKU uses a G1/4 port, PT thread form, and an M14x1.5 rod-end thread.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (LB / FA / SDB) and back cover (CA pivot / U flat-end).
- check Installation by qualified personnel per AirTAC docs.
Airtac MBL Aluminum Alloy Mini Cylinder MBL50X25-CA FAQ
This 50mm bore cylinder generates 981 N push and 881 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a maximum theoretical force of 200 kgf at 1.0 MPa.
The base MBL uses a fixed rubber bumper that cannot be adjusted; for adjustable air cushioning, you need the MBLC variant. Additionally, this specific SKU lacks a built-in magnet, so no CMSG, DMSG, or EMSG sensor switch can be fitted for position detection.
