About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X450SU
The AirTAC MBLC32X450SU is a double-acting aluminum mini cylinder engineered for compact spaces requiring a long 450 mm stroke. It delivers 402 N of push force at 0.5 MPa and utilizes a screw-adjustable pneumatic cushion at both stroke ends. Unlike the base MBL with its fixed rubber bumper, this cushion lets you fine-tune end-of-stroke deceleration to match your load and speed, cutting impact shock and vibration on heavier or faster moves.
This configuration includes a built-in magnet (-S) for CMSG, DMSG, or EMSG sensor switches, and a U flat-end back cover for rigid rear mounting. The riveted rolling-packed aluminum barrel keeps the body light, while the Ø12 mm carbon-steel rod features 20 µm hard-chrome plating to resist wear. A heterogeneous two-way grease-retaining piston seal ensures consistent lubrication across the 30-800 mm/s speed range.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X450SU Is Used
Carton Flap Folding
Drives a 450 mm arm to fold large corrugated carton flaps on a packaging line, using the 402 N force and tuned cushion to prevent end-cover slamming on fast strokes.
PCB Edge Pusher
Transfers long printed circuit boards between conveyor belts in electronics assembly, where the built-in magnet confirms full extension and the compact barrel fits tight machine gaps.
Textile Roll Diverting
Actuates a diverter arm to sort fabric rolls on a material handling line, relying on the adjustable air cushion to smoothly stop the 450 mm stroke under a heavy dynamic load.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X450SU the Right Cylinder?
At 0.5 MPa, this 32 mm bore generates 402 N push and 346 N pull force. If you need less force, step down to the 25 mm bore (245 N push); if your load requires more thrust, step up to the 40 mm bore (628 N push). Choose this MBLC variant over the standard MBL when your application cycles quickly or moves enough mass that a fixed rubber bumper would wear out prematurely. The adjustable needle decelerates the piston smoothly near the ends but does not lock the rod; for position holding without air, use an external rod lock.
With a 450 mm stroke on a Ø12 mm rod, side-load tolerance is low and the risk of rod bending increases. To manage this, use an external guide rail, select a CA or SDB pivot bracket to absorb arcing loads, or switch to an MBLD double-rod cylinder. This exact replacement matches: 32 mm bore, 450 mm stroke, G1/8 port, PT thread, U flat-end cover, and an -S magnet.

- ✓ 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 MBLC32X450SU FAQ
This 32 mm bore cylinder has a G1/8 port and generates 402 N push / 346 N pull at 0.5 MPa, 563 N push / 484 N pull at 0.7 MPa, and a maximum theoretical force of 82 kgf at 1.0 MPa.
A screw-tunable needle at both ends traps exhaust air to decelerate the piston smoothly before it hits the end cover. You adjust it to match your specific load and speed, which reduces impact noise and wear compared to the fixed rubber bumper found on the base MBL series.
