About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X150CA
The AirTAC MBLC50X150CA is a double-acting aluminum mini cylinder featuring a 50 mm bore and 150 mm stroke, engineered to deliver 981 N of push force at 0.5 MPa. Unlike the standard base MBL which relies on a fixed rubber bumper, this variant incorporates a screw-adjustable pneumatic air cushion at both stroke ends. This allows you to precisely tune the end-of-stroke deceleration, effectively minimizing impact shock and vibration when moving heavier masses at high cycling frequencies.
The riveted rolling-packed aluminum barrel keeps the overall body compact and lightweight for tight spaces, while the 20 µm hard-chrome plated carbon-steel rod pairs with a heterogeneous two-way grease-retaining piston seal to ensure lasting friction control. This specific SKU is configured with a CA pivot/clevis back cover, allowing the cylinder to swing on a pin to accommodate arcing loads. Note that it lacks a built-in magnet, meaning it cannot support CMSG, DMSG, or EMSG electronic position sensors.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X150CA Is Used
Bottling Line Diverter
Drives a 150 mm swing arm to route filled 2-liter beverage containers between labeling and capping stations, utilizing the 981 N push force and CA clevis to manage the arcing trajectory smoothly.
Textile Loom Take-Up
Actuates a fabric tensioning guide on high-speed weaving equipment, where the tunable air cushion absorbs the kinetic energy of the 50 mm bore piston to prevent end-cover damage during rapid 150 mm strokes.
Palletizing Box Pusher
Transfers heavy corrugated cardboard cartons onto a descending pallet tier, relying on the double-acting 881 N pull force to retract the arm while the pivot bracket absorbs lateral stress.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X150CA the Right Cylinder?
When sizing this actuator, consider stepping down to the 40 mm bore if your application requires only 628 N of push force at 0.5 MPa, or stepping up to the 63 mm bore if you need a substantial 1558 N to overcome higher friction or heavier payloads. The 50 mm bore utilizes a G1/4 port and an M14x1.5 rod-end thread. Choose this MBLC variant over the fixed-bumper MBL specifically when operating speeds are high or the moved mass is heavy enough that a standard rubber bumper would degrade prematurely.
Because this configuration uses a CA pivot back cover, it is specifically suited for kinetic arcing or side-loaded movements where a rigid flat-end U cover would induce binding. Remember that the adjustable air cushion only decelerates the piston near the end of its travel; it is not a mechanical lock. If the air supply is lost or the directional valve centers, the rod will drift and drop, so an external pilot-operated check valve or rod lock is required to hold a load safely in place.
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 MBLC50X150CA FAQ
At a 0.5 MPa operating pressure, this 50 mm bore cylinder provides 981 N of push force and 881 N of pull force. If you increase the supply to 0.7 MPa, the push force rises to 1374 N. The maximum theoretical force is 200 kgf at 1.0 MPa.
The MBLC50X150CA features a screw-tunable needle valve at both ends that traps and bleeds exhaust air to decelerate the piston smoothly near the stroke ends. You tune the needle to match the load and speed, cutting impact noise and vibration. It is strictly a deceleration device and does not lock or hold the rod position when air is removed.
