About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X125SU
The AirTAC MBLC32X125SU is a double-acting, 32mm bore mini cylinder engineered with a 125mm stroke. It produces 402 N of push force and 346 N of pull force at 0.5 MPa, making it well-suited for mid-range positioning tasks. The defining feature of this MBLC variant is the screw-adjustable pneumatic cushioning at both stroke ends, which decelerates the piston smoothly to prevent end-cover impact on faster cycles.
This model includes a built-in magnet (indicated by the S code) for compatibility with AirTAC CMSG, DMSG, and EMSG sensor switches to track rod position. The U code specifies a rigid flat-end back cover. Constructed with a riveted rolling-packed aluminum barrel for tight spaces, it relies on a heterogeneous two-way grease-retaining piston seal and a 20 µm hard-chrome plated carbon-steel rod for lasting friction control.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X125SU Is Used
Packaging Carton Flaps
Provides 402 N of push force at 0.5 MPa to reliably fold corrugated cardboard flaps on high-speed packaging lines, utilizing the adjustable cushion to prevent harsh slamming at the 125mm stroke end.
PCB Test Handlers
Moves testing probes into position over printed circuit boards, using the built-in magnet with a DMSG sensor to confirm exact 125mm extension before initiating the electrical test sequence.
Textile Beam Indexing
Shifts weaving beams laterally into loom cradles, relying on the tunable end-of-stroke deceleration to minimize machine vibration during frequent, rapid 125mm indexing moves.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X125SU the Right Cylinder?
If your application requires less force, stepping down to the 25mm bore yields 245 N of push force at 0.5 MPa. Conversely, upgrading to the 40mm bore provides 628 N of push force for heavier loads. Choose this MBLC version over the base MBL when your cycle speeds are too high for a fixed rubber bumper to safely absorb the kinetic energy without causing premature wear.
As a 125mm stroke unit, it is below the 300mm threshold where severe rod bending typically occurs, but the 12mm rod still offers low side-load tolerance, so axial alignment is critical. For drop-in replacements, match the 32mm bore, 125mm stroke, G1/8 port, PT thread, U back cover, and the -S magnet. Note that the adjustable cushion only decelerates the piston near the ends; it is not a brake and will not hold the rod in place if air pressure is lost.
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 MBLC32X125SU FAQ
This 32mm bore cylinder delivers 402 N push and 346 N pull at 0.5 MPa, 563 N push and 484 N pull at 0.7 MPa, with a maximum theoretical output of 82 kgf at 1.0 MPa.
A screw-tunable needle at both ends traps a small pocket of exhaust air to smoothly decelerate the piston near the stroke limits. You adjust the needle to match your specific load and speed, which cuts impact noise and protects the end covers far better than a fixed rubber bumper.
