About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X50U
The AirTAC MBLC32X50U is a double-acting, 32mm bore aluminum mini cylinder with a 50mm stroke. It delivers 402N of push force and 346N of pull force at 0.5 MPa. The U suffix denotes a rigid flat-end back cover for direct mounting. This model lacks a built-in magnet, meaning it cannot support CMSG, DMSG, or EMSG position sensors.
Unlike the base MBL series, this MBLC variant features a screw-adjustable pneumatic cushion at both ends. You tune the needle valve to smoothly decelerate the piston near the stroke limits, absorbing kinetic energy to protect the end covers during fast cycling. The riveted rolling-packed aluminum barrel keeps the body compact for tight spaces, while the 20-micron hard-chrome plating on the carbon-steel rod defends against friction and minor corrosion.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X50U Is Used
PCB Router Spindle
Z-axis positioning for a printed circuit board routing spindle, using the 402N thrust to lower the cutting motor while the air cushion prevents a jarring impact that could damage the precision bearings.
Bottle Divert Gate
Actuating a diverter gate on a 30mm wide packaging conveyor, where the 50mm stroke pushes lightweight cartons off the main belt at high frequency without wearing the rear cover.
Small Part Ejector
Ejecting molded plastic caps from an injection press tooling plate, utilizing the 346N pull force to retract the kicker pin reliably under 0.5 MPa air pressure.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X50U the Right Cylinder?
If you need less force, the 25mm bore offers 245N push at 0.5 MPa, whereas stepping up to the 40mm bore yields 628N. Choose this MBLC version over the fixed-bumper MBL when your cycle speeds are high enough that impact damage is a concern. Since this specific SKU has no -S suffix, it cannot accept a reed or electronic sensor switch. For replacements, match the 32mm bore, 50mm stroke, G1/8 port, M10x1.25 rod thread, PT port thread form, and U flat-end 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 MBLC32X50U FAQ
At 0.5 MPa, this 32mm bore cylinder provides 402N of push force and 346N of pull force. At 0.7 MPa, the push force increases to 563N. The maximum theoretical force is 82 kgf at 1.0 MPa.
A screw-tunable needle valve at both ends traps a pocket of exhaust air to decelerate the piston smoothly before it hits the end cover. You adjust it to match the load and speed, which reduces noise and impact stress. It is strictly an end-of-stroke deceleration device, not a mid-stroke brake or load lock.
