About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X40U
The AirTAC MBLC40X40U is a double-acting aluminum mini cylinder with a 40 mm bore and 40 mm stroke. It generates 628 N of push force and 528 N of pull force at 0.5 MPa. The U suffix denotes a rigid flat-end back cover for straightforward inline mounting. Because this specific SKU lacks the -S magnet suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor.
Unlike the base MBL which relies on a fixed rubber bumper, this MBLC variant features a screw-adjustable pneumatic cushion at both ends. You tune the needle valve to smoothly decelerate the 16 mm hard-chrome carbon-steel piston rod near the stroke limits, absorbing kinetic energy on faster moves. The riveted rolling-packed aluminum barrel keeps the overall body compact and lightweight for tight machine envelopes.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X40U Is Used
CNC Lathe Tool Turret
Indexes a small tooling carousel with 628 N of push force, utilizing the adjustable cushion to prevent shock damage to the precision turret mechanism.
Bottle Divert Gate
Actuates a routing flap on a packaging line where the 40 mm stroke provides rapid redirection, while the cushioned ends minimize impact vibration.
PCB Test Socket Clamp
Secures an electronic test fixture with 528 N of pull force, using the tunable deceleration to protect fragile circuit boards from sudden end-stop jolts.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X40U the Right Cylinder?
At 0.5 MPa, this 40 mm bore yields 628 N push and 528 N pull. If your payload is lighter, stepping down to the 32 mm bore reduces the footprint and yields 402 N push / 346 N pull. If you are moving heavier masses, stepping up to the 50 mm bore provides 981 N push / 881 N pull. Choose this MBLC over the fixed-bumper MBL when your cycle speeds are high enough that impact shock would damage the end covers. The adjustable air cushion only decelerates the rod near the ends; it is not a brake and will not hold the load if air pressure drops. For exact replacement, match the 40 mm bore, 40 mm stroke, G1/4 port, M12x1.25 rod thread, PT port thread, and the U flat-end back cover.
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 MBLC40X40U FAQ
The 40 mm bore uses a G1/4 port and a Ø16 mm rod with an M12x1.25 rod-end thread. At 0.5 MPa it provides 628 N push and 528 N pull. At 0.7 MPa it provides 880 N push and 739 N pull. The maximum theoretical force is 128 kgf at 1.0 MPa.
No. Because this specific SKU lacks the -S suffix, it has no built-in magnet and cannot accept CMSG, DMSG, or EMSG sensor switches. If you need position feedback, select the MBLC40X40SU model instead.
