About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X500CA
The AirTAC MBLC40X500CA is a double-acting aluminum mini cylinder engineered for demanding 500 mm strokes. It generates 628 N of push force and 528 N of pull force at 0.5 MPa. A built-in adjustable air cushion at both ends allows you to screw-tune the end-of-stroke deceleration, absorbing kinetic energy to prevent end-cover impact on long, fast moves.
This SKU features a CA pivot clevis back cover that swings on a pin to accommodate arcing loads. It uses a G1/4 port and a Ø16 mm carbon-steel rod with 20 µm hard-chrome plating. Because this model lacks the -S suffix, it has no internal magnet and cannot accept CMSG, DMSG, or EMSG position sensors. The riveted rolling-packed aluminum barrel keeps the body compact while surviving high-cycle operations.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X500CA Is Used
Robotic Arm Extension
Drives a 500 mm reach on a secondary pick-and-place arm, utilizing the CA pivot to absorb angular misalignment while the air cushion prevents shock at full extension.
Pallet Transfer Pusher
Shifts heavy pallets between roller conveyors, using the 628 N push force to overcome inertia while the cushioning softens the 500 mm travel stop.
Vertical Lift Gate
Actuates a 500 mm vertical material lift gate where the clevis mount accommodates lateral swing and the tunable cushion protects the gate mechanism from slamming.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X500CA the Right Cylinder?
At 0.5 MPa, this 40 mm bore yields 628 N push and 528 N pull. If your application requires less force, step down to the 32 mm bore (402 N push); if you need more power, step up to the 50 mm bore (981 N push). Choose this MBLC variant over the base MBL when your 500 mm stroke runs at high speed or high frequency, as the fixed rubber bumper on the MBL cannot adequately absorb the kinetic energy.
A 500 mm stroke generates significant leverage on the Ø16 mm rod, meaning side loads can cause premature wear or bending. The CA pivot clevis on this unit helps by self-aligning angular loads, but for rigid radial loads you should add an external guide rail, use an SDB pivot bracket, or switch to an MBLD double-rod cylinder. Note that the adjustable air cushion only decelerates the piston near the ends; it is not a brake and will not hold the load if air pressure is lost or the valve centers.
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 MBLC40X500CA FAQ
This 40 mm bore cylinder provides 628 N push and 528 N pull at 0.5 MPa, 880 N push and 739 N pull at 0.7 MPa, and a maximum theoretical output of 128 kgf at 1.0 MPa.
A screw-tunable needle at both stroke ends releases trapped air to smoothly decelerate the piston, preventing end-cover impact on fast 500 mm moves. It is strictly a deceleration device, not a load lock or brake.
