About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X175U
The AirTAC MBLC40X175U is a compact double-acting aluminum mini cylinder engineered to deliver 628 N of push force and 528 N of pull force at 0.5 MPa. Its 175 mm stroke provides the extended travel needed for mid-range positioning tasks. Unlike the standard MBL bumper variant, this MBLC model incorporates a screw-adjustable pneumatic air cushion at both stroke ends. Tuning the cushion needle allows you to smoothly decelerate the piston, minimizing end-cover impact and vibration during rapid or heavy moves.
This unit features a robust riveted rolling-packed aluminum barrel that keeps the overall body compact and lightweight for tight machine envelopes, rather than relying on a bulky rebuildable tie-rod design. Internally, a heterogeneous two-way grease-retaining piston seal works alongside a 20 um hard-chrome plated carbon-steel rod (Ø16 mm) to ensure consistent lubrication and wear resistance. Because this specific SKU lacks the -S magnet code, it cannot accept a CMSG, DMSG, or EMSG position sensor switch.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X175U Is Used
PCB Handling Conveyor Gate
Actuates a diverter gate on a printed circuit board assembly line, using the 175 mm stroke to route panels smoothly without shocking the lightweight aluminum framing.
Carton Flap Folding Arm
Drives a mechanical arm to fold corrugated carton flaps prior to sealing, relying on the adjustable air cushion to prevent slamming as the 628 N push force completes the fold.
Bottle Sorting Diverter
Pushes plastic bottles into a sorting lane on a packaging conveyor, where the cushioned end-of-stroke deceleration keeps the glass or PET containers from tipping over.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X175U the Right Cylinder?
Select the 40 mm bore when your application requires the 628 N push force at 0.5 MPa, bridging the gap between the 32 mm bore (402 N push) and the larger 50 mm bore (981 N push). The 175 mm stroke suits mechanisms needing moderate extension, but at this length the 16 mm rod has a higher susceptibility to side-load bending; use an external guide rail, a pivot bracket, or an MBLD double-rod cylinder to prevent binding.
Choose the MBLC over the base MBL when your cycle speeds or moved masses outpace the deceleration capacity of a fixed rubber bumper. This configuration uses a G1/4 port, PT thread form, M12x1.25 rod-end thread, and a U flat-end back cover for rigid rear mounting. Note that the adjustable air cushion only decelerates the piston near the stroke ends; it is not a locking brake, so the rod will drift if air pressure is lost or the valve centers.
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 MBLC40X175U FAQ
At 0.5 MPa, this 40 mm bore cylinder provides 628 N of push force and 528 N of pull force. At 0.7 MPa, the push increases to 880 N. The theoretical maximum holding force is 128 kgf at 1.0 MPa. It uses a G1/4 port and an M12x1.25 rod-end thread.
No, this specific SKU does not have the -S code, meaning it lacks a built-in magnet and cannot support CMSG, DMSG, or EMSG sensor switches. If you require electronic or reed switch position detection, you must order the -S magnet variant of this cylinder.
