About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X150U
The AirTAC MBLC50X150U is a double-acting aluminum mini cylinder engineered with a screw-adjustable pneumatic cushion at both stroke ends. Generating 981 N of push force and 881 N of pull force at 0.5 MPa, this 50 mm bore unit is tailored for rapid, heavier mass transitions where a fixed rubber bumper would fail. The 150 mm stroke provides ample travel for intermediate indexing tasks.
Unlike tie-rod rebuildable bodies, this actuator features a riveted rolling-packed aluminum barrel for compact, lightweight integration into tight machine envelopes. It utilizes a heterogeneous two-way grease-retaining piston seal alongside a 20 um hard-chrome plated carbon-steel rod to sustain lubrication and resist wear across high cycle counts. The U flat-end back cover provides a rigid rear mounting interface, and because this specific SKU lacks the -S magnet code, it cannot support CMSG, DMSG, or EMSG position sensing.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X150U Is Used
Bottling Line Diverter
Routes heavy 2-liter PET bottle traffic on a 150 mm stroke at high frequency, using the tuned pneumatic cushion to halt the 981 N thrust gently without jarring the conveyor frame.
CNC Lathe Chip Conveyor
Indexes a metal scrap conveyor drawer with 881 N of pull force, relying on adjustable end-deceleration to prevent impact shock from fracturing the cast aluminum end covers.
Palletizing Stop Gate
Acts as a rigid U-mounted stop for inbound pallets, absorbing kinetic energy via the needle-adjustable cushion rather than transferring destructive vibration into the surrounding machine structure.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X150U the Right Cylinder?
When sizing this 50 mm bore actuator, step down to the 40 mm variant if your load requires less than 628 N of push force at 0.5 MPa, or step up to the 63 mm bore to acquire 1558 N of push force for heavier displacement. Choose this MBLC cushioned version over the base MBL when your cycle speeds exceed the absorption capacity of a standard rubber bumper, protecting the end covers from impact damage. For position verification, note that this exact U-cover configuration ships without a magnet; you must select an -S coded variant to mount CMSG reed or DMSG/EMSG solid-state sensors. Replacement match: 50 mm bore, 150 mm stroke, G1/4 port, PT thread, U back cover, no magnet.
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 MBLC50X150U FAQ
At 0.5 MPa, the push force is 981 N and the pull force is 881 N. At 0.7 MPa, the push increases to 1374 N. The maximum theoretical force is 200 kgf at 1.0 MPa operating pressure.
A screw-tunable needle valve at each end traps a pocket of exhaust air to decelerate the piston smoothly before contact. You adjust the needle to match your load and speed, which reduces end-cover impact, noise, and vibration. It only decelerates near the stroke ends; it is not a brake and does not hold position if air pressure is lost.
