About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X15U
The AirTAC MBLC20X15U is a compact double-acting aluminum mini cylinder with a 20 mm bore and 15 mm stroke. It generates 157 N of push force and 132 N of pull force at 0.5 MPa. Unlike the base MBL, this variant features a screw-adjustable pneumatic cushion at both ends, allowing you to tune the end-of-stroke deceleration to match the load and speed. This protects the end covers and reduces noise on fast, repetitive moves. The U suffix denotes a rigid flat-end back cover for straightforward inline mounting.
Built around a riveted rolling-packed aluminum barrel, the body remains light and fits into tight machine cavities where tie-rod cylinders cannot. The Ø8 mm carbon-steel rod features 20 µm hard-chrome plating for wear resistance, paired with a heterogeneous two-way grease-retaining piston seal. Note that this specific SKU lacks a built-in magnet, so it cannot host a CMSG, DMSG, or EMSG position sensor without modification.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X15U Is Used
PCB Edge-Guide Deflection
Provides 157 N of push at 0.5 MPa to nudge circuit boards laterally on a conveyor, using the 15 mm stroke to clear guide rails before routing.
IC Test Socket Ejection
Uses the short 15 mm stroke to eject packaged integrated circuits from a test socket, relying on the adjustable air cushion to prevent chip damage at cycle end.
Small Parts Sorting Gate
Actuates a diverter gate on a high-speed pharmaceutical blister pack line, where the compact 20 mm barrel fits within the tight sorting head clearance.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X15U the Right Cylinder?
Select this 20 mm bore when you need precise, short 15 mm movements and roughly 157 N of push force at 0.5 MPa. If your application requires even less force, the next size down does not exist in this mini series, making 20 mm the most compact option available. If you need more power, stepping up to the 25 mm bore yields 245 N of push force at 0.5 MPa. Choose the MBLC over the fixed-bumper MBL when cycling speeds are high enough that a rubber bumper cannot adequately absorb the impact. Because this is a double-acting cylinder, it does not hold position if air pressure drops; for fail-safe holding, add an external rod lock. Replacement parts must match the G1/8 port, M8x1.25 rod thread, PT thread form, and U flat-end back cover.
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 MBLC20X15U FAQ
At 0.5 MPa, the MBLC20X15U provides 157 N of push force and 132 N of pull force. At 0.7 MPa, it delivers 220 N of push force. The theoretical maximum force is 32 kgf at 1.0 MPa.
The MBLC20X15U has a screw-tunable pneumatic cushion at both ends. You adjust the needle valve to trap exhaust air, decelerating the piston smoothly near the stroke end. This reduces impact and vibration on fast moves, but it is not a load lock or brake.
