About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X500SU
The AirTAC MBLC63X500SU is a double-acting aluminum mini cylinder engineered for substantial thrust, delivering 1558 N push and 1457 N pull at 0.5 MPa. A 500 mm stroke suits extended traverse or lifting movements in machinery. Unlike the base MBL, this MBLC variant incorporates a screw-adjustable pneumatic cushion at both ends. You tune the needle to smoothly decelerate the piston near stroke extremes, mitigating end-cover impact on fast, heavy loads.
This SKU includes a built-in magnet (-S) for compatibility with AirTAC CMSG, DMSG, and EMSG sensor switches to track rod position. It features a U flat-end back cover for rigid mounting and a G1/4 port. The riveted rolling-packed aluminum barrel keeps the body compact, while the 20 µm hard-chrome plated carbon-steel rod resists wear. Heterogeneous two-way grease-retaining piston seals maintain lubrication across the 30-800 mm/s speed range.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X500SU Is Used
Palletizer Strapper Arm
Drives a 500 mm strapping head feed arm on an end-of-line palletizer, using the adjustable cushion to arrest the 1558 N thrust smoothly without shocking the frame.
Vertical Lift Gate
Actuates a 500 mm vertical lift gate on a heavy-duty packaging conveyor, relying on the DMSG electronic sensor to confirm gate open/close positions.
Board Stacking Reject
Pushes oriented strand boards out of a stacking line, using the full 500 mm stroke to clear the conveyor path while the pneumatic cushion softens the heavy retraction stop.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X500SU the Right Cylinder?
At 500 mm stroke, the Ø16 rod is highly susceptible to side-load bending and buckling under off-center loads. For this length, guide the load externally, use a CA or SDB pivot bracket to absorb arcing forces, or switch to an MBLD double-rod cylinder to prevent rod drift. If you need to step down, the 50 mm bore provides 981 N push at 0.5 MPa; if you require more force, this 63 mm bore is the largest available in the series, peaking at 318 kgf theoretical at 1.0 MPa. Choose the MBLC over the base MBL when cycling high masses at high frequency, as the fixed rubber bumper of the MBL cannot absorb the kinetic energy this bore generates.
Replacement match: bore 63, stroke 500, port G1/4, rod thread M14x1.5, PT port thread, U flat-end back cover, built-in magnet (-S). Note that a plain MBLC does not hold position when air is lost or the valve centers; the rod drifts. The air cushion only decelerates near the ends and is not a load lock or brake.
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 MBLC63X500SU FAQ
The cylinder operates at 0.15-1.0 MPa. At 0.5 MPa it pushes with 1558 N and pulls with 1457 N. At 0.7 MPa it pushes with 2181 N. The maximum theoretical force is 318 kgf at 1.0 MPa.
A screw-tunable needle at both ends traps a pocket of exhaust air to decelerate the piston smoothly near the stroke extremes. You adjust it to match the load and speed, reducing impact and noise on high-frequency heavy moves. It is not a load lock or brake; the rod will drift if air is lost.
