About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X50SCA
The AirTAC MBLC50X50SCA is a double-acting aluminum mini cylinder featuring a 50 mm bore and 50 mm stroke. It generates 981 N of push force and 881 N of pull force at 0.5 MPa, making it well-suited for moderately heavy positioning tasks. Unlike the base MBL series, this variant utilizes a screw-adjustable pneumatic cushion at both ends to smoothly decelerate the piston near stroke limits, effectively minimizing impact shock and vibration on faster moves.
This specific SKU includes a built-in magnet (-S) for compatibility with AirTAC CMSG, DMSG, and EMSG electronic sensor switches to detect rod position. The CA pivot/clevis back cover allows the body to swing on a pin, accommodating arcing angular loads. The hard-chrome plated carbon-steel rod and heterogeneous two-way grease-retaining piston seal are housed within a riveted, rolling-packed aluminum barrel, ensuring a compact, lightweight footprint that fits easily into tight machinery layouts.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X50SCA Is Used
CNC Lathe Bar Feeder
Pushes raw bar stock into the collet with 981 N of force at 0.5 MPa, using the tunable cushion to prevent end-of-stroke impact when cycling rapidly.
Pallet Transfer Pivot
Utilizes the CA clevis back cover to swing a diverter arm between conveyor lanes, absorbing angular momentum during the 50 mm stroke.
Packaging Flap Folder
Folds carton flaps at high speed, relying on the CMSG reed switch to confirm position and the air cushion to protect the end covers from repetitive heavy impacts.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X50SCA the Right Cylinder?
If you need to step down in force, the neighboring 40 mm bore provides 628 N of push at 0.5 MPa, whereas stepping up to the 63 mm bore yields 1558 N of push at 0.5 MPa. Choose the MBLC over the fixed-bumper MBL when your application cycles at high frequency or moves a heavier mass that requires tunable end-of-stroke deceleration. Note that the adjustable cushion only decelerates the piston near the ends; it is not a brake and will not hold a load if air pressure is lost or the valve centers.
As a direct replacement match, this cylinder has a 50 mm bore, 50 mm stroke, G1/4 port, PT thread, CA pivot back cover, and a built-in magnet. For this 50 mm stroke, side-load tolerance is manageable, but always ensure the clevis pin is adequately lubricated to prevent binding during arcing motions.
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 MBLC50X50SCA 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, the push force increases to 1374 N. The maximum theoretical force is 200 kgf at 1.0 MPa.
The cushion is a screw-tunable needle at both ends that traps exhaust air to decelerate the piston smoothly near the stroke limits. You tune the needle to match your load and speed, which cuts impact noise and protects the end covers on fast moves. It is strictly a deceleration device, not a load lock or brake.
