About the Airtac MBL Aluminum Alloy Mini Cylinder MBL50X20-CA
The AirTAC MBL50X20-CA is a compact double-acting aluminum mini round cylinder engineered to deliver 981 N of push force at 0.5 MPa within a tight 20 mm stroke. Its CA pivot back cover features a clevis design that swings on a pin, making it the right choice for arcing or angular load trajectories where a rigid flat-end mount would induce binding. The riveted rolling-packed aluminum barrel keeps the body light and small for tight machine spaces, though it is not designed to be disassembled and rebuilt like a tie-rod cylinder.
This SKU lacks the -S magnet suffix, so it cannot accept a CMSG, DMSG, or EMSG position sensor switch. The piston relies on a heterogeneous two-way seal that retains grease for long service life, while the carbon steel rod features 20 um hard-chrome plating for wear and corrosion resistance. End-of-stroke impact is absorbed by a fixed rubber bumper rather than an adjustable air cushion.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL50X20-CA Is Used
Pallet Diverters
Drives short 20 mm push strokes on conveyor pivot arms to deflect pallets onto branch lanes, using the 981 N force to overcome carton drag.
Press Brake Fingers
Swings an angular tooling finger into position via the CA clevis, fitting the compact riveted body into the tight gaps of a sheet metal brake.
Bin Lid Ejection
Pivots heavy bin lids open on packaging lines where the CA back cover accommodates the arcing motion of the hinge without binding.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL50X20-CA the Right Cylinder?
At 0.5 MPa this 50 mm bore generates 981 N push and 881 N pull force. If your mechanism needs less force, step down to the 40 mm bore (628 N push), or if you need more power, step up to the 63 mm bore (1558 N push). Choose the MBLC variant if your application requires adjustable air cushioning for heavier moving masses, or the MSBL/MTBL single-acting versions if you only need spring-return push or pull action. Keep in mind that a plain MBL does not hold its position or load when air pressure is lost or the valve is centred; the rod drifts, so use an external rod lock or pilot-operated check valve if gravity or load holding is a concern.
Replacement match: 50 mm bore, 20 mm stroke, G1/4 port, PT thread form, CA pivot back cover, no magnet. The 20 mm stroke is short enough that side-load bending on the Ø16 mm rod is minimal, but always ensure the CA clevis pin is aligned with the load's arc to prevent bearing wear.
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 MBL50X20-CA FAQ
At 0.5 MPa the push force is 981 N and the pull force is 881 N. At 0.7 MPa the push force reaches 1374 N, with a maximum theoretical force of 200 kgf at 1.0 MPa. The double-acting speed range is 30-800 mm/s.
This specific SKU lacks the -S magnet suffix, so no CMSG, DMSG, or EMSG sensor switch can be fitted. For cushioning, the base MBL uses a fixed rubber bumper; if you need adjustable air cushioning for heavier end-of-stroke impacts, you must switch to the MBLC variant.
