About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X60SU
The AirTAC MBLC40X60SU is a double-acting aluminum mini cylinder with a 40 mm bore and 60 mm stroke. It generates 628 N of push force and 528 N of pull force at 0.5 MPa. The built-in magnet (-S) supports CMSG, DMSG, and EMSG sensor switches for precise rod position detection. A 60 mm stroke is optimal for short, rapid positioning tasks where stopping smoothness directly impacts product quality.
Unlike the base MBL series which relies on a fixed rubber bumper, this MBLC variant features a screw-adjustable pneumatic air cushion at both ends. You tune the exhaust needle to match the load and velocity, smoothly decelerating the piston to protect the end covers from impact on high-frequency cycles. The riveted rolling-packed aluminum barrel keeps the body compact for tight machine layouts, while the 20 µm hard-chrome plated carbon-steel rod resists wear against the heterogeneous two-way grease-retaining piston seal.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X60SU Is Used
Spindle Loading Arm
Drives a short-stroke robotic arm to load raw metal billets into a CNC lathe chuck, using the 628 N thrust to seat the part firmly before clamping.
Pallet Diverters
Actuates a routing gate on a 60 mm stroke to divert packaged electronics boxes on a high-speed conveyor, relying on the air cushion to prevent gate slam.
Tray Stacker Lifter
Raises small component trays inside a tight electronics assembly cell, where the compact riveted barrel fits restricted vertical spaces and the magnet confirms the lift stroke.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X60SU the Right Cylinder?
At 0.5 MPa, this 40 mm bore yields 628 N push and 528 N pull force. If your payload is lighter, stepping down to the 32 mm bore reduces the footprint while still providing 402 N push and 346 N pull. If your mechanism requires more thrust, the 50 mm bore offers 981 N push and 881 N pull. Choose the MBLC over the standard MBL when your cycle speed or moved mass causes harsh end-of-stroke collisions that a fixed rubber bumper cannot absorb. The U flat-end back cover provides rigid axial mounting. Note that the adjustable air cushion only decelerates the piston near the stroke ends; it is not a brake. A plain pneumatic cylinder will drift if air is lost or the valve centers, so fit an external rod lock if you need true fail-safe position holding. Replacement matches: 40 mm bore, 60 mm stroke, G1/4 port, PT thread, U back cover, magnet included.
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 MBLC40X60SU FAQ
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At 0.7 MPa, the push force increases to 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa.
The MBLC40X60SU uses a screw-tunable pneumatic needle at both ends instead of a fixed rubber bumper. By adjusting the needle, you control the exhaust air flow to smoothly decelerate the piston near the end of the 60 mm stroke, reducing impact noise and protecting the end covers on fast cycles.
