About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X100U
The AirTAC MBLC50X100U is a double-acting aluminum mini cylinder with a 50 mm bore and 100 mm stroke, delivering 981 N of push force at 0.5 MPa. It features a screw-adjustable pneumatic cushion at both ends, letting you tune the end-of-stroke deceleration to match heavier loads and faster cycle speeds. This protects the end covers from impact, unlike the fixed rubber bumper found on the base MBL series.
This U-coded variant uses a rigid flat-end back cover for straightforward inline mounting. The riveted rolling-packed aluminum barrel keeps the body compact and lightweight for tight spaces. Inside, a heterogeneous two-way grease-retaining piston seal and a 20 µm hard-chrome plated carbon-steel rod ensure smooth, low-friction operation. Note that this specific SKU lacks a built-in magnet, so it cannot support CMSG, DMSG, or EMSG position sensors.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X100U Is Used
Injection Mold Extraction
Pulls heavy plastic parts from injection molds at high speed, using the tuned air cushion to prevent the 881 N pull force from slamming the rear cover.
Packaging Diverter Arm
Actuates a heavy diverter gate on a packaging line, where the 100 mm stroke and 981 N push force reliably redirect filled cartons without impact shock.
PCB Pressing Station
Applies controlled downward pressure on electronic connectors, relying on the adjustable cushion to gently seat components before the stroke ends.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X100U the Right Cylinder?
At 0.5 MPa, this 50 mm bore generates 981 N push and 881 N pull. If your application requires less force, the 40 mm bore neighbor provides 628 N push, while stepping up to the 63 mm bore yields 1558 N. Choose this MBLC cushioned version over the standard MBL when your 100 mm move runs at high speeds or shifts a heavy mass that would overwhelm a fixed rubber bumper. The adjustable air cushion only decelerates the piston near the stroke ends; it is not a load lock or brake, and the rod will drift if air is lost or the valve centers. For position holding without live air, install an external rod lock or pilot-operated check valve.
Replacement match: 50 mm bore, 100 mm stroke, G1/4 port, PT thread, U flat-end back cover, no magnet (non-S).
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 MBLC50X100U FAQ
This 50 mm bore cylinder provides 981 N push and 881 N pull at 0.5 MPa, 1374 N push and 1233 N pull at 0.7 MPa, and a maximum theoretical force of 200 kgf at 1.0 MPa.
A screw-tunable needle at both ends traps a pocket of exhaust air to decelerate the piston smoothly near the stroke limits. You adjust it to match your load and speed, reducing impact and noise. It only decelerates near the ends and does not lock the load.
