About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X20CA
The AirTAC MBLC50X20CA is a compact double-acting aluminum mini cylinder engineered for short 20 mm strokes where high force and smooth deceleration are critical. It delivers a robust 981 N of push force at 0.5 MPa, utilizing a Ø16 hard-chrome carbon-steel rod and a heterogeneous two-way grease-retaining piston seal to maintain consistent friction. 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 protect the end covers on fast, heavy moves.
This specific SKU is configured with a CA pivot back cover that swings on a pin to accommodate arcing or angular loads, making it superior to rigid flat-end mounts for linkages. The riveted rolling-packed aluminum barrel keeps the body light and compact for tight machine spaces. Note that because this model lacks the -S suffix, it is built without a magnet and cannot host a CMSG, DMSG, or EMSG position sensor switch.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X20CA Is Used
Short-Stroke Stamping Press
Ideal for driving a high-force 981 N stamping die in a compact 20 mm travel, where the tunable air cushion absorbs the rapid end-of-stroke impact to protect the tooling.
Pivot Arm Diverter
The CA pivot back cover securely handles the angular side-loads of a swinging diverter arm on a packaging line, maintaining smooth motion as it rapidly redirects product.
PCB Edge Guide Clamping
Provides rigid 50 mm bore holding power for electronics assembly fixtures, using the short stroke to clamp delicate PCBs without overshooting or crashing the end cover.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X20CA the Right Cylinder?
Select this 50 mm bore when an application demands high thrust—981 N push and 881 N pull at 0.5 MPa—in a very short 20 mm travel. If you need less force, stepping down to the 40 mm bore yields 628 N of push, while moving up to the 63 mm bore provides 1558 N for heavier payloads. Choose this MBLC cushioned version over the fixed rubber bumper of the standard MBL when your cycling speeds are high enough that impact noise and cover wear become a concern.
For replacement matching, verify the G1/4 port, PT thread form, Ø16 rod with an M14x1.5 end thread, and the CA clevis back cover. Because this SKU has no internal magnet, you cannot add a reed or solid-state sensor; if position detection is required, order an -S variant. Finally, remember that the adjustable air cushion only decelerates the piston near the stroke ends; it is not a brake and will not hold the load if air pressure is lost.
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 MBLC50X20CA FAQ
This 50 mm bore cylinder uses a Ø16 mm rod with an M14x1.5 end thread and a G1/4 port. At 0.5 MPa it provides 981 N push and 881 N pull force. At 0.7 MPa, push increases to 1374 N. The maximum theoretical force is 200 kgf at 1.0 MPa.
The MBLC features a screw-adjustable air cushion at both ends, letting you tune the deceleration to eliminate the harsh impact noise and end-cover wear that occurs with fixed rubber bumpers on fast cycles. This cushion is strictly for end-of-stroke deceleration and is not a lock; the cylinder will not hold position if air is exhausted or the valve centers.
