About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X15SU
The AirTAC MBLC20X15SU is a compact double-acting aluminum mini cylinder engineered for tight spaces. It delivers 157 N of push force and 132 N of pull force at 0.5 MPa. The 15 mm stroke is ideal for very short, precise positioning tasks. Unlike the base MBL, this variant features a screw-adjustable pneumatic cushion at both ends to tame end-of-stroke impact.
The riveted rolling-packed aluminum barrel keeps the body light and compact, fitting where tie-rod cylinders cannot. Inside, a heterogeneous two-way grease-retaining piston seal works alongside a 20-micron hard-chrome-plated carbon-steel rod. The built-in magnet (-S) supports CMSG, DMSG, and EMSG sensor switches for rod position detection.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X15SU Is Used
PCB Depaneling Router
Provides 157 N of push at 0.5 MPa to actuate a precision routing blade on an electronics assembly line, with the 15 mm stroke ensuring rapid cycling.
Sorter Diverter Gate
Snaps a small pneumatic diverter gate for lightweight plastic component sorting, utilizing the tunable air cushion to prevent harsh impact on the 15 mm stroke end.
Micro-Clamp Actuation
Drives a small testing fixture clamp in a laboratory automation cell, where the double-acting operation and compact 20 mm bore fit within tight machine geometry.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X15SU the Right Cylinder?
For slightly less force, the next size down is the 16 mm bore (if available) or you might step up to the 25 mm bore, which provides 245 N push at 0.5 MPa. Choose this MBLC over the base MBL when your cycle speed is high enough that a fixed rubber bumper would wear quickly. The U flat-end back cover provides rigid mounting. Note that the adjustable air cushion only decelerates the piston near the ends; it is not a lock, so the rod will drift if air is lost. Replacement match: 20 mm bore, 15 mm stroke, G1/8 port, PT thread, U back cover, flat-end mounting, with magnet.
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 MBLC20X15SU FAQ
At 0.5 MPa, the push force is 157 N and the pull force is 132 N. At 0.7 MPa, the push force is 220 N. The theoretical maximum force is 32 kgf at 1.0 MPa.
The cushion is a screw-tunable needle valve at both ends that traps exhaust air to decelerate the piston smoothly near the stroke limits. You tune it to match the load and speed, cutting impact noise on fast cycles. It only decelerates; it does not lock or hold the load in place.
