About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X20SU
The AirTAC MBLC63X20SU is a double-acting aluminum mini cylinder engineered for high-force, short-travel tasks. It generates 1558 N of push force and 1457 N of pull force at 0.5 MPa, making this 63 mm bore, 20 mm stroke unit ideal for tight-space pressing. Unlike the base MBL, this variant features a screw-adjustable pneumatic cushion at both ends. You can tune the needle to smoothly decelerate the heavy 318 kgf-capable piston, preventing end-cover impact on rapid cycles.
This SKU includes a built-in magnet (S) for CMSG, DMSG, or EMSG sensor switches, enabling precise end-of-stroke detection. The U flat-end back cover provides rigid rear mounting, while the riveted rolling-packed aluminum barrel keeps the assembly light. Inside, a heterogeneous two-way grease-retaining piston seal runs against a 20 µm hard-chrome plated carbon-steel rod, ensuring lasting lubrication for millions of actuations.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X20SU Is Used
PCB Staking Press
Drives a 20 mm stroke to seat connectors onto printed circuit boards, using the 1558 N push force to firmly embed pins without damaging the fiberglass substrate.
Bearing Insertion
Pushes bushings into aluminum housings on an assembly carousel, relying on the adjustable air cushion to stop the 318 kgf-capable piston softly before it bottoms out.
Connector Latching
Snaps rigid locking tabs into electronic enclosures, using the DMSG sensor signal to confirm the 20 mm extension before the robotic handler retracts.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X20SU the Right Cylinder?
Select this 63 mm bore when a compact footprint must deliver substantial thrust. If you need less force, stepping down to the 50 mm bore yields 981 N of push at 0.5 MPa; stepping up is not possible as 63 mm is the largest MBL/MBLC size. Choose the MBLC over the fixed-bumper MBL when cycling heavy loads quickly and needing tunable end-of-stroke deceleration. The adjustable cushion only decelerates the piston near the ends—it is not a lock. The cylinder will drift if air is lost, so fit an external rod lock for position holding without live air. This exact replacement matches: 63 mm bore, 20 mm stroke, G1/4 port, PT thread, U flat-end cover, and an S magnet.

- ✓ 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 MBLC63X20SU FAQ
At 0.5 MPa it provides 1558 N push and 1457 N pull. At 0.7 MPa it outputs 2181 N push. The maximum theoretical force is 318 kgf at 1.0 MPa.
A screw-tunable needle traps exhaust air at both stroke ends to decelerate the heavy 63 mm piston. You dial it in to match the load speed, cutting impact noise and vibration. It only decelerates near the ends and does not lock the rod in place.
