About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X300U
The AirTAC MBLC32X300U is a double-acting, single-rod mini cylinder engineered with a screw-adjustable pneumatic cushion at both stroke ends. Delivering 402 N of push force and 346 N of pull force at 0.5 MPa, it is built around a riveted, rolling-packed aluminum barrel that keeps the body compact and lightweight rather than relying on a heavy, rebuildable tie-rod assembly. The 300 mm stroke provides ample travel for positioning tasks, while the U flat-end back cover offers a rigid, straightforward mounting interface.
This variant uses a Ø12 mm carbon-steel piston rod plated with 20 µm of hard chrome to resist wear and corrosion. Inside, a heterogeneous two-way grease-retaining piston seal maintains lubrication over long cycles. Because this specific SKU lacks the -S magnet code, it cannot accept a CMSG, DMSG, or EMSG position sensor. The adjustable air cushion allows you to tune the end-of-stroke deceleration to match your load and speed, absorbing kinetic energy to protect the end covers on fast, heavy moves.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X300U Is Used
CNC Lathe Bar Feeder
Pushes raw bar stock through a spinning collet with 402 N of force, using the 300 mm stroke to index material precisely while the tuned air cushion prevents end-of-stroke impact from damaging the feeder tube.
Pallet Divert Arm
Actuates a routing flap on a packaging conveyor over a 300 mm travel distance, relying on the adjustable cushion to smoothly decelerate the arm and avoid jarring the adjacent product flow.
Vertical Lift Gate
Raises a lightweight access gate on a testing machine, using the U flat-end back cover for rigid mounting and the pneumatic cushion to bring the gate to a gentle stop at the top of its travel.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X300U the Right Cylinder?
With a 402 N push at 0.5 MPa, this 32 mm bore sits right in the middle of the mini cylinder range. If your application requires less force, stepping down to the 25 mm bore yields 245 N of push force. If you need to move a heavier payload, stepping up to the 40 mm bore provides 628 N. Choose this MBLC cushioned version over the base MBL when your cycle speeds are high enough that a fixed rubber bumper would transmit excessive shock to the machine frame.
For position sensing, note that this specific U-flat-end configuration is shipped without a magnet and cannot host a CMSG, DMSG, or EMSG switch. Because the 300 mm stroke is relatively long for a Ø12 mm rod, side-load tolerance is low. You should use an external guide rail to prevent rod bending, or pivot to a CA clevis or SDB pivot bracket to accommodate arcing loads. A plain double-acting cylinder will drift if air is lost, so add an external rod lock if you need fail-safe holding.
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 MBLC32X300U FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 346 N of pull force. At 0.7 MPa, the push increases to 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa.
A screw-tunable needle at both ends of the cylinder traps a pocket of exhaust air to decelerate the piston smoothly before it hits the end cover. You adjust the needle to match your specific load and speed, which cuts noise and vibration on fast cycles. It only decelerates near the stroke ends and does not lock or hold the load in place.
