About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X350SU
The AirTAC MBLC32X350SU is a double-acting, single-rod aluminum mini cylinder engineered for compact actuation over a 350 mm stroke. It integrates a built-in magnet (-S) for non-contact position detection using CMSG reed or DMSG and EMSG electronic sensor switches. The U suffix designates a rigid flat-end rear cover, providing a straightforward threaded mounting interface for stationary equipment frames. Generating 402 N of push force and 346 N of pull force at 0.5 MPa, it is tailored for mid-range linear tasks.
Unlike the standard MBL series which relies on a fixed rubber bumper, this MBLC variant features a screw-adjustable pneumatic air cushion at both stroke ends. Tuning the cushion needle allows you to smoothly decelerate the piston near the end caps, mitigating impact shock and vibration on faster or heavier traverses. The riveted rolling-packed aluminum barrel keeps the overall body compact and lightweight, while the 20 µm hard-chrome plated carbon-steel rod resists wear against the heterogeneous two-way grease-retaining piston seal.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X350SU Is Used
CNC Lathe Bar Feeder
Pushes raw bar stock through a spindle feeder tube; the 350 mm stroke handles long stock lengths while the 402 N force at 0.5 MPa advances the material reliably against cutting resistance.
Packaging Reject Diverter
Extends a paddle arm to knock defective cartons off a high-speed main conveyor line, utilizing the tunable air cushion to halt the 350 mm extension smoothly without slamming the frame.
PCB Panel Transfer
Moves populated electronics panels from a test fixture to a buffer station, using the -S magnet and DMSG electronic sensor to confirm the full 350 mm transfer stroke completed before the robot unloads.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X350SU the Right Cylinder?
When sizing this 32 mm bore actuator, consider stepping down to the 25 mm bore if your load requires less force (it yields 245 N push at 0.5 MPa), or stepping up to the 40 mm bore for heavier payloads (providing 628 N push at 0.5 MPa). Choose this MBLC cushioned model over the base MBL when your application cycles rapidly or moves enough mass that a fixed rubber bumper would degrade or cause unacceptable end-of-stroke noise.
With a 350 mm stroke, the 12 mm rod is highly susceptible to bending under lateral loads; always guide the payload externally or utilize a pivot mounting style to prevent rod damage. Furthermore, a plain double-acting cylinder does not hold position if air pressure drops or the valve centers—the rod will drift. The adjustable air cushion only decelerates the piston near the stroke ends and functions as a speed damper, not as a mechanical lock or brake. For position holding without live air, specify an external rod lock. This specific configuration features a G1/8 port, M10x1.25 rod-end thread, and default PT (tapered) threading.

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 MBLC32X350SU FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 346 N of pull force. If you increase the operating pressure to 0.7 MPa, the output rises to 563 N push and 484 N pull. The maximum theoretical force is 82 kgf at the 1.0 MPa operating pressure limit.
The MBLC32X350SU uses a screw-tunable pneumatic needle at both ends to trap and bleed exhaust air, decelerating the piston smoothly before it contacts the end cover. You adjust the needle to match your specific load and speed, which prevents the hard, repetitive impact and noise of a fixed rubber bumper on long, fast 350 mm strokes.
