About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X50CA
The AirTAC MBLC20X50CA is a compact double-acting aluminum mini cylinder engineered for tight spaces, featuring a 20 mm bore and a 50 mm stroke. It utilizes a CA pivot back cover that swings on a pin, making it ideal for arcing or angular loads where a rigid flat-end mount would induce binding. Delivering 157 N of push force at 0.5 MPa, it is built around a riveted rolling-packed aluminum barrel that keeps the body light without requiring a bulky tie-rod assembly.
Unlike the base MBL which relies on a fixed rubber bumper, this MBLC variant features a screw-adjustable pneumatic air cushion at both ends. Tuning the needle valve allows you to decelerate the piston smoothly near each stroke end, effectively cutting end-cover impact, noise, and vibration on faster or heavier moves. The unit uses a heterogeneous two-way grease-retaining piston seal and a 20 µm hard-chrome plated carbon-steel rod. Note that this specific SKU lacks a built-in magnet and cannot support a CMSG, DMSG, or EMSG position sensor.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X50CA Is Used
Wire Cutting Feeders
Drives a pivoting arm that feeds wire into a cutting head, using the CA clevis to accommodate the arc of the mechanism while the air cushion prevents end-of-stroke bounce at high speed.
PCB Component Sorting
Pushes small electronic components into sorting tubes, where the 157 N force is sufficient for light parts and the tunable cushion ensures delicate handling without harsh impacts.
Packaging Flap Diverters
Actuates a lightweight swing diverter on a packaging conveyor, relying on the pivot mount to track the moving belt arc while the 50 mm stroke rapidly redirects cartons.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X50CA the Right Cylinder?
Select this 20 mm bore when your application requires 157 N of push force at 0.5 MPa within a highly constrained footprint. If you need less force, the smaller 20 mm is the minimum available size in this series, so you would look outside the family for a lighter unit. If your load requires more power, stepping up to the 25 mm bore yields 245 N of push force at 0.5 MPa. The CA clevis mount is essential here for accommodating angular motion, and the standard PT tapered port threads match common domestic pneumatic fittings.
Choose this MBLC version over the standard MBL when your cycle speeds or payload masses exceed what a fixed rubber bumper can safely absorb. Because this SKU is shipped without a magnet (-S), it cannot provide rod-position feedback; if your sequence requires end-of-stroke confirmation, you must select an MBLC20X50CAS variant instead. Remember 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.
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 MBLC20X50CA FAQ
This 20 mm bore cylinder uses a G1/8 port and an M8x1.25 rod thread. At 0.5 MPa it provides 157 N push and 132 N pull force. At 0.7 MPa, push increases to 220 N and pull to 185 N. The maximum theoretical force is 32 kgf at 1.0 MPa.
A screw-tunable needle valve at both ends traps a small amount of exhaust air to decelerate the piston smoothly before it hits the end cover. You adjust it to match your specific load and speed, which reduces impact wear and noise compared to a fixed rubber bumper. It functions only as an end-of-stroke damper, not as a load-holding brake.
