About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X75SU
The AirTAC MBLC32X75SU is a compact, double-acting aluminum mini cylinder engineered for tight spaces. It delivers 402 N of push force and 346 N of pull force at 0.5 MPa. The 75 mm stroke is ideal for short-travel automation tasks. Unlike the base MBL, this variant uses a screw-adjustable pneumatic cushion at both ends to smoothly decelerate the piston near stroke limits, cutting impact noise and end-cover wear on faster cycles.
This SKU includes a built-in magnet (-S) for compatibility with AirTAC CMSG, DMSG, and EMSG sensor switches to track rod position. It features a U flat-end back cover for rigid mounting and a riveted rolling-packed aluminum barrel that keeps the body light. The Ø12 mm carbon-steel rod is plated with 20 µm hard chrome, paired with a heterogeneous two-way grease-retaining piston seal for lasting friction control.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X75SU Is Used
PCB Depaneling Router
Drives a linear blade or saw across a populated circuit board, using the 75 mm stroke to separate panels precisely while the air cushion prevents end-impact vibration that could damage microchips.
Carton Flap Folder
Folds minor corrugated box flaps at 402 N of push force, completing its 75 mm travel quickly without slamming the rear U flat-end cover, ensuring quiet operation on high-speed packaging lines.
Connector Insertion Press
Pushes electronic headers into sockets on an assembly fixture, using the -S magnet to trigger a DMSG solid-state sensor for position confirmation before applying the final 346 N pull force.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X75SU the Right Cylinder?
At 0.5 MPa, this 32 mm bore generates 402 N push and 346 N pull. If your payload is lighter, step down to the 25 mm bore (245 N push), or step up to the 40 mm bore (628 N push) for heavier masses. Choose the MBLC over the fixed-bumper MBL when cycling quickly or moving a heavier load that requires tunable end-of-stroke deceleration. Note that the air cushion only slows the piston near the ends; it is not a brake, so the rod will drift if air is lost.
For replacements, match the 32 mm bore, 75 mm stroke, G1/8 port, M10x1.25 rod thread, PT thread form, U flat-end back cover, and the -S magnet. The 75 mm stroke is short enough that side-load bending is minimal, but the 8-16 mm rod class still has low side-load tolerance, so use a guide for offset loads.
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 MBLC32X75SU 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, push increases to 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa. It uses a G1/8 port, an Ø12 mm rod with an M10x1.25 thread, and operates at speeds of 30-800 mm/s.
The MBLC32X75SU features a screw-tunable pneumatic needle at both ends. You adjust the needle to match your load and speed, trapping a pocket of air to smoothly decelerate the piston before it hits the end cover. This reduces impact noise and wear compared to a fixed rubber bumper, but it does not lock or hold the rod position when air is removed.
