About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X75U
The AirTAC MBLC50X75U is a double-acting aluminum mini cylinder with a 50 mm bore and 75 mm stroke. It generates 981 N of push force and 881 N of pull force at 0.5 MPa. Unlike the base MBL series, this variant uses a screw-adjustable pneumatic cushion at both stroke ends. You tune the needle to decelerate the piston smoothly, cutting end-cover impact and vibration on faster or heavier moves.
The U suffix denotes a rigid flat-end rear cover for straightforward inline mounting. The riveted rolling-packed aluminum barrel keeps the body compact, while the Ø16 mm carbon-steel rod features 20 µm hard-chrome plating to resist wear. Note that this specific SKU lacks a built-in magnet, so it cannot host a CMSG, DMSG, or EMSG position sensor.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X75U Is Used
Injection Mold Ejection
Provides 981 N of push force to eject plastic parts from molds, using the adjustable air cushion to prevent harsh impacts during high-speed ejection.
Package Diverting
Powers a diverting arm on packaging lines, where the 75 mm stroke and tunable end-of-travel cushioning halt the load smoothly without bouncing.
Pallet Stopper
Acts as a compact stopper for medium-sized pallets, using its 881 N pull force to retract the rod clear of the conveyor path.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X75U the Right Cylinder?
This 50 mm bore yields 981 N push at 0.5 MPa. If your application requires less force, step down to the 40 mm bore (628 N push); if you need more power, the 63 mm bore provides 1558 N. Choose this MBLC cushioned model over the fixed-bumper MBL when your cycle speeds exceed the limits of rubber absorption. Because this is a U-type flat-end cylinder, it does not pivot—use an FA flange or SDB bracket for arcing loads.
For a direct replacement, match the 50 mm bore, 75 mm stroke, G1/4 port, PT thread, U flat-end back cover, and no magnet. Since this SKU lacks the -S suffix, adding position sensing requires switching to an MBLC50X75SU model. A plain double-acting cylinder drifts when air is removed; the air cushion only decelerates near the ends and does not lock the rod.
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 MBLC50X75U FAQ
At 0.5 MPa, it provides 981 N of push force and 881 N of pull force. At 0.7 MPa, the push force reaches 1374 N. The theoretical maximum force is 200 kgf at 1.0 MPa.
No, this specific SKU lacks the -S suffix, meaning it has no built-in magnet and cannot host CMSG, DMSG, or EMSG sensor switches. You would need the MBLC50X75SU model for position detection.
