About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X150SCA
The AirTAC MBLC40X150SCA is a double-acting aluminum mini cylinder with a 40 mm bore and 150 mm stroke. It generates 628 N of push force and 528 N of pull force at 0.5 MPa. A built-in magnet (-S) allows CMSG, DMSG or EMSG sensor switches to track rod position. The CA pivot clevis back cover swings on a pin to accommodate arcing loads. A screw-adjustable pneumatic cushion at both ends decelerates the piston smoothly near stroke limits. This protects the end covers from impact on fast or heavy moves. It is a compact riveted rolling-packed body, not a rebuildable tie-rod design.
The 16 mm carbon-steel rod features 20 µm hard-chrome plating for wear resistance. A heterogeneous two-way grease-retaining piston seal maintains lubrication over a 30-800 mm/s speed range. The G1/4 port matches the 40 mm bore's flow requirements. The cushion needle is tunable to match your specific load and velocity, reducing noise and vibration. This cylinder is ideal for compact spaces needing precise end-of-stroke control without ISO 15552 bulk.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X150SCA Is Used
Textile Loom Beat-Up
Drives the reed mechanism at high frequency, using the tunable cushion to silence end-of-stroke impact and protect the aluminum end covers from 628 N of shock force.
Pallet Transfer Pivot
Leverages the CA clevis pin to swing a diverter arm on a packaging line, smoothly decelerating the 150 mm stroke to prevent jarring pallet jumps.
Board Stacking Flap
Actuates a cardboard flap guide on a corrugated box machine, using the -S magnet and DMSG sensor to confirm retraction before the next sheet drops.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X150SCA the Right Cylinder?
Step down to the 32 mm bore if your load requires only 402 N of push force at 0.5 MPa. Step up to the 50 mm bore if you need 981 N to move heavier assemblies. Choose this MBLC over the base MBL when your cycle speeds are high or the moved mass is substantial, as the fixed rubber bumper on the MBL cannot absorb higher kinetic energy. The CA pivot clevis on this unit is essential for arcing loads, preventing side-load binding. The -S magnet enables position detection via CMSG reed or DMSG/EMSG electronic switches. The PT threaded port and M12x1.25 rod thread are standard for this 40 mm bore. A plain air cushion only decelerates the piston near the ends; it does not lock the rod. If you need position holding without live air, add an external rod lock or pilot-operated check valve.
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 MBLC40X150SCA FAQ
At 0.5 MPa, it provides 628 N of push force and 528 N of pull force. At 0.7 MPa, push increases to 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa.
A screw-tunable needle at both ends traps exhaust air to decelerate the piston smoothly, preventing end-cover damage on fast moves. The -S built-in magnet works with CMSG reed or DMSG/EMSG electronic switches for non-contact position detection.
