About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X300SCA
The AirTAC MBLC50X300SCA is a double-acting, 50mm bore aluminum mini cylinder with a 300mm 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 fixtures through longer travel distances. The riveted rolling-packed aluminum barrel keeps the body compact and lightweight rather than relying on bulky tie-rods. Inside, a heterogeneous two-way grease-retaining piston seal works alongside a 20 µm hard-chrome plated carbon-steel rod to ensure smooth, low-friction cycling.
This SKU includes a built-in magnet (-S) for compatibility with AirTAC CMSG, DMSG, and EMSG sensor switches to track rod position along its 300mm travel. The CA back cover provides a pivot/clevis mount that allows the cylinder to swing on a pin, absorbing angular misalignment during arcing motions. Because this is the MBLC variant, it features a screw-adjustable pneumatic air cushion at both ends instead of a fixed rubber bumper, allowing you to tune the end-of-stroke deceleration to protect the end covers on faster, heavier moves.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X300SCA Is Used
Robotic Palletizing Arm
Drives a 300mm reach extension on a packaging robot, using the 981 N thrust to push cartons while the CA clevis absorbs angular rod misalignment during arcing movements.
Bottle Divert Gate
Actuates a heavy stainless steel diverting gate on a high-speed beverage line, where the adjustable air cushion prevents hard end-cover impacts during rapid 300mm strokes.
Warehouse Sorter Pusher
Ejects heavier totes from a sorting conveyor, relying on the built-in magnet to trigger an AirTAC DMSG electronic sensor at full 300mm extension before retracting.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X300SCA the Right Cylinder?
Stepping down in bore size, the 40mm neighbor provides 628 N of push force at 0.5 MPa, while stepping up to the 63mm bore yields 1558 N—choose the 50mm when your load requires 981 N of thrust. Select the MBLC over the base MBL when your cycle speeds or moving mass exceed what a fixed rubber bumper can safely absorb. Note that the adjustable air cushion only decelerates the piston near the stroke ends; it is not a brake and will not hold the load if air pressure is lost or the valve centers.
With a 300mm stroke, the Ø16 mm rod is highly susceptible to bending under side loads. For this CA pivot model, ensure the clevis pin is perfectly lubricated and consider an external guide rail to support the load, or switch to an MBLD double-rod cylinder if rotational resistance is needed. Replacement requires matching the 50mm bore, 300mm stroke, G1/4 port, PT thread, CA pivot cover, and the magnetic -S option.
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 MBLC50X300SCA FAQ
At 0.5 MPa, this 50mm bore cylinder provides 981 N of push force and 881 N of pull force. At 0.7 MPa, push increases to 1374 N. The maximum theoretical force is 200 kgf at 1.0 MPa.
A screw-tunable needle at both stroke ends bleeds trapped air to smoothly decelerate the piston before contact. You adjust it to match your specific load and speed, which reduces vibration, noise, and end-cover wear compared to a fixed rubber bumper.
