About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X500U
The AirTAC MBLC50X500U is a double-acting aluminum mini cylinder with a 50 mm bore and 500 mm stroke, delivering 981 N of push force at 0.5 MPa. It uses a U flat-end back cover for rigid mounting. Because this specific SKU lacks the -S suffix, it has no built-in magnet and cannot accept CMSG, DMSG, or EMSG position sensors. A screw-adjustable air cushion at both ends decelerates the piston smoothly near stroke extremes, which is critical for managing the momentum of a 500 mm travel distance.
This cylinder features a riveted rolling-packed aluminum barrel for a compact, lightweight profile that fits tight spaces, unlike bulky tie-rod bodies. The Ø16 carbon-steel rod is protected by 20 µm hard-chrome plating, and a heterogeneous two-way grease-retaining piston seal ensures consistent lubrication over long cycles. Operating pressure ranges from 0.15 to 1.0 MPa, with a speed range of 30-800 mm/s.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X500U Is Used
Pallet Diverters
Drives long-stroke diverting arms on packaging lines, using the adjustable cushion to softly stop a 981 N push force without slamming into the end cap.
Injection Mold Ejection
Extends 500 mm to push heavy molded parts clear of the press, relying on the hard-chrome plated Ø16 rod to resist wear during repetitive ejection.
Vertical Tray Lifters
Lifts stacked component trays in tight machine cells where the compact riveted aluminum barrel saves space, requiring an external guide to manage side loads.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X500U the Right Cylinder?
Choose this 50 mm bore when you need 981 N push at 0.5 MPa over a long 500 mm stroke. If your application requires less force, step down to the 40 mm bore, which provides 628 N push at 0.5 MPa. If you need more power, the 63 mm bore offers 1558 N push at 0.5 MPa. Select the MBLC over the fixed-bumper MBL when moving heavier masses at high speeds, as the tunable needle protects the end covers from impact. Note that a plain MBLC does not hold position when air is lost; use an external rod lock for pilot-operated check for vertical holding.
At 500 mm, this stroke reaches the maximum standard limit before special orders are required. The Ø16 rod has low side-load tolerance over this distance, so an external guide, a CA/SDB pivot bracket, or an MBLD double-rod cylinder is recommended to prevent rod bending. This SKU uses a G1/4 port, M14x1.5 rod-end thread, PT port thread, and a U flat-end back cover.
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 MBLC Aluminum Alloy Mini Air Cylinder MBLC50X500U FAQ
This 50 mm bore cylinder uses a Ø16 mm rod with an M14x1.5 rod-end thread and a G1/4 port. It 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.
No, this specific SKU lacks the -S suffix, meaning it has no built-in magnet and cannot support CMSG, DMSG, or EMSG sensor switches. You would need the MBLC50X500SU variant to enable electronic or reed switch position detection.
