About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X250CA
The AirTAC MBLC50X250CA is a double-acting aluminum mini cylinder with a 50 mm bore and 250 mm stroke. It delivers 981 N of push force and 881 N of pull force at 0.5 MPa, making it well-suited for moving heavier masses over longer distances. The riveted rolling-packed aluminum barrel keeps the body compact and lightweight rather than relying on bulky tie-rods.
This variant uses a CA pivot (clevis) back cover that swings on a pin to accommodate arcing or angular loads. Unlike the base MBL which relies on a fixed rubber bumper, this MBLC model features a screw-adjustable pneumatic air cushion at both ends. You tune the needle to smoothly decelerate the piston near the stroke limits, cutting impact shock and vibration on high-speed moves. Note that this specific SKU lacks a built-in magnet (-S), so it cannot support a CMSG, DMSG, or EMSG position sensor.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X250CA Is Used
Packaging Conveyor Diverter
Swings a heavy routing gate on a packaging line, using the 981 N push force at 0.5 MPa to redirect filled cartons while the air cushion absorbs the 250 mm stroke's end-of-travel momentum.
Textile Loom Tensioning
Arms a heavy guide bar on a textile machine; the CA clevis accommodates the angular rod path while the cushion needle damps vibration on fast, repetitive stroking.
Palletizer Load Push-Off
Pushes stacked goods off a low-profile palletizer station, relying on the tunable air cushion to prevent hard end-cover impacts when shifting significant mass over 250 mm.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X250CA the Right Cylinder?
If you need to step down, the 40 mm bore provides 628 N of push force at 0.5 MPa; stepping up to the 63 mm bore yields 1558 N. Choose the MBLC over the base MBL when your application runs at high speeds or high cycle frequencies where a fixed bumper would degrade. Because this 250 mm stroke is substantial, the 16 mm carbon-steel rod has limited side-load tolerance; you must use an external guide, the CA pivot mount, or a double-rod MBLCD to prevent rod bending. For replacement matching, verify the 50 mm bore, 250 mm stroke, G1/4 port, PT thread, CA pivot back cover, and 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 MBLC50X250CA FAQ
At 0.5 MPa, this 50 mm bore cylinder provides 981 N of push force and 881 N of pull force. At 0.7 MPa, it provides 1374 N of push force. The maximum theoretical force is 200 kgf at 1.0 MPa.
The MBLC50X250CA has a screw-tunable pneumatic cushion at both ends. You adjust the needle to match your load and speed, smoothly decelerating the piston near the stroke limits to protect the end covers. It only decelerates near the ends and is not a load lock or brake.
