About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X75SU
The AirTAC MBLC20X75SU is a compact double-acting aluminum mini cylinder engineered for tight spaces where precise end-of-stroke control is essential. It generates 157 N of push force and 132 N of pull force at 0.5 MPa across its 75 mm stroke. Unlike the standard bumper version, this model features a screw-adjustable pneumatic air cushion at both ends, allowing you to tune the deceleration profile to match your load and speed, thereby reducing impact noise and end-cover stress during rapid cycling.
Built with a riveted rolling-packed aluminum barrel for a lightweight yet rigid structure, it houses an Ø8 mm carbon-steel rod with 20 µm hard-chrome plating to resist wear. The heterogeneous two-way grease-retaining piston seal maintains consistent lubrication over the 30-800 mm/s speed range. The built-in magnet (-S) supports position detection via AirTAC CMSG, DMSG, or EMSG sensor switches, while the U flat-end back cover provides a rigid, flush rear mounting face.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X75SU Is Used
PCB Depaneling Saw Feed
Drives a small cutting blade carriage across a 75 mm travel. The adjustable air cushion ensures the 8 mm rod decelerates smoothly before the end cap, preventing jarring stops that could snap fragile printed circuit board edges.
Pharmacy Pill Dispenser
Pushes a metering gate to drop exact tablet quantities. The 157 N thrust at 0.5 MPa easily shifts the light gate, while the compact 20 mm barrel fits neatly inside the dense dispensing cabinet.
Connector Pin Insertion
Presses delicate electronic pins into housings. The tunable cushion allows the stroke to end with a soft landing, protecting the pin tips from damage during high-frequency assembly cycles.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X75SU the Right Cylinder?
Select this 20 mm bore when an application demands exactly 157 N of thrust at 0.5 MPa within a compact footprint. If your load requires less force, stepping down is not possible as 20 mm is the smallest available size in this series; however, if you need significantly more power, the 25 mm bore provides 245 N of push force at 0.5 MPa. Choose the MBLC over the base MBL when operating at higher speeds or moving heavier masses that would overwhelm a fixed rubber bumper. The adjustable cushion needle decelerates the piston near the stroke ends but does not lock the rod; if position holding without continuous air pressure is required, an external rod lock or pilot-operated check valve must be fitted.
This specific configuration uses a PT tapered port thread, an M8x1.25 rod-end thread, and a U flat-end back cover. The -S designation confirms the internal magnet is fitted for CMSG (reed) or DMSG/EMSG (electronic) switches. If your mechanism involves arcing loads rather than straight-line motion, you would pivot to a CA back cover instead of this rigid U type.
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 MBLC20X75SU FAQ
At 0.5 MPa, this 20 mm bore cylinder provides 157 N of push force and 132 N of pull force. At 0.7 MPa, the push increases to 220 N. The theoretical maximum force is 32 kgf at 1.0 MPa. It features an Ø8 mm rod, an M8x1.25 rod-end thread, and a G1/8 port.
The integrated air cushion at both ends uses a screw-adjustable needle to trap and bleed exhaust air, decelerating the piston smoothly near the stroke ends to protect the end covers on fast moves. It is strictly a deceleration device, not a brake; the cylinder cannot hold a load in place if air pressure is lost or the valve is centered.
