About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X60SU
The AirTAC MBLC20X60SU is a compact double-acting mini cylinder engineered for tight spaces. It produces 157 N push and 132 N pull force at 0.5 MPa, making the 60 mm stroke well suited for short, rapid positioning tasks. Unlike the base MBL, this variant features a screw-adjustable pneumatic cushion at both ends. You can tune the needle to smoothly decelerate the piston near stroke limits, cutting end-cover impact and vibration on fast moves.
This unit includes a built-in magnet for CMSG, DMSG, or EMSG sensor switches. The riveted rolling-packed aluminum barrel keeps the body light and compact, while the Ø8 carbon-steel rod features 20 µm hard-chrome plating for wear resistance. The U flat-end back cover provides a rigid rear mount for straightforward in-line installation.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X60SU Is Used
PCB Depaneling Saw
Feeds a circular saw blade in 60 mm increments. The tuned air cushion halts the 157 N push stroke smoothly to prevent blade chatter on the cut edge.
Chip Test Handler
Actuates a small reject gate on a semiconductor test line. The compact 20 mm barrel fits the tight cluster, and the DMSG sensor tracks the gate position.
Pharmacy Vial Sorting
Pushes lightweight plastic vials into a divert channel. The adjustable cushion decelerates the rod quietly, protecting the small parts from impact cracks.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X60SU the Right Cylinder?
At 0.5 MPa, this 20 mm bore yields 157 N of push force. If your payload requires less thrust, the series stops here as the smallest size. If you need more power, stepping up to the 25 mm bore provides 245 N push at 0.5 MPa. Choose the MBLC over the base MBL when cycle frequency or moving mass makes the fixed rubber bumper insufficient for end-of-stroke deceleration.
For replacement matching, verify the 20 mm bore, 60 mm stroke, G1/8 port, M8x1.25 rod thread, PT thread form, U flat-end back cover, and the -S magnet. Note that a plain MBLC does not hold position if air is lost; the cushion only decelerates near the ends and acts as no brake. For position holding without live air, use an external rod 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 MBLC20X60SU FAQ
At 0.5 MPa, the 20 mm bore provides 157 N push and 132 N pull force. At 0.7 MPa, it yields 220 N push. The maximum theoretical force is 32 kgf at 1.0 MPa.
A screw needle at each end traps exhaust air to decelerate the piston smoothly near the stroke limits. You tune the needle to match the load and speed, reducing impact on the end covers. It is a deceleration device, not a load lock or brake.
