About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X175U
The AirTAC MBLC20X175U is a compact double-acting aluminum mini cylinder engineered with a screw-adjustable pneumatic cushion at both stroke ends. Delivering 157 N of push force and 132 N of pull force at 0.5 MPa, it is tailored for fast, light-load cycling where fixed rubber bumpers would wear prematurely. The 175 mm stroke suits longer-travel pick-and-place arms or thin-sheet indexing tasks. Its riveted rolling-packed aluminum barrel keeps the overall envelope small and lightweight for tight machine cavities.
This SKU features a rigid U flat-end back cover and a PT-threaded G1/8 port. The Ø8 mm carbon-steel rod carries a 20 μm hard-chrome plating to resist scoring, while the heterogeneous two-way grease-retaining piston seal maintains lubrication over high-frequency cycles. Because this specific configuration lacks the -S magnet code, it cannot host a CMSG, DMSG, or EMSG position sensor switch.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X175U Is Used
PCB Depaneling Router
Drives a routing blade across 175 mm to singulate populated circuit boards, using the adjustable air cushion to prevent end-cover shock on fast indexing moves.
IC Tray Ejection
Pushes empty matrix trays out of a test handler with 157 N of thrust at 0.5 MPa, relying on the compact riveted barrel to fit the dense ejector station.
Pharma Carton Flap Folding
Folds small carton flaps over a 175 mm travel path, where the hard-chrome plated Ø8 mm rod withstands thousands of repetitive actuations without scoring.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X175U the Right Cylinder?
Select this 20 mm bore when a compact footprint and 157 N thrust at 0.5 MPa meet your payload needs. If you require less force, the smaller 16 mm bore is not available in the MBL series, making the 20 mm the smallest option. If your load demands greater thrust, step up to the 25 mm bore, which provides 245 N push at 0.5 MPa. Choose the MBLC over the base MBL when your cycle speeds exceed the limits of a fixed rubber bumper. For replacement matching, confirm the 175 mm stroke, G1/8 port, PT thread, U back cover, and no magnet. Because the stroke is 175 mm, the small Ø8 mm rod has lower side-load tolerance; use an external guide rail to prevent rod bending on long moves. Note that this plain double-acting cylinder does not hold position if air is lost—the cushion only decelerates near the ends, it is not a lock.
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 MBLC20X175U FAQ
This double-acting cylinder generates 157 N push and 132 N pull at 0.5 MPa, 220 N push at 0.7 MPa, and a maximum theoretical force of 32 kgf at 1.0 MPa. It uses a screw-adjustable pneumatic air cushion at both ends to decelerate the piston smoothly near the stroke extremes.
No, this specific SKU lacks the built-in magnet (the -S code) and therefore cannot accept AirTAC CMSG reed or DMSG/EMSG electronic sensor switches. If you need position feedback, select the MBLC20X175S variant instead.
