About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X175U
The AirTAC MBLC50X175U is a double-acting aluminum mini cylinder with a 50 mm bore and 175 mm stroke. It generates 981 N of push force and 881 N of pull force at 0.5 MPa, making it well-suited for moving heavier masses through a mid-range travel distance. The U designation indicates a rigid flat-end back cover for straightforward inline mounting.
Unlike the base MBL series which relies on a fixed rubber bumper, this MBLC variant features a screw-adjustable pneumatic air cushion at both ends. Tuning the cushion needle allows you to smoothly decelerate the piston near the stroke extremes, absorbing kinetic energy to protect the end covers during fast or high-frequency cycles. The riveted rolling-packed aluminum barrel keeps the body compact, while the 20 µm hard-chrome plating on the carbon-steel rod defends against wear. Note that because this specific SKU lacks the -S suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor switch.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X175U Is Used
Packaging Conveyor Diverters
Drives 175 mm diverter arms on high-speed packaging lines, using the adjustable cushion to softly stop the 981 N push force without jarring the product.
Injection Mold Extraction
Extracts heavier plastic injection molded parts from tight press cavities, relying on the tunable end-cushioning to prevent impact during rapid retraction.
Palletizing Pushers
Pushes corrugated cartons into palletizing stations, where the rigid U back cover withstands inline thrust and the air cushion absorbs the load energy.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X175U the Right Cylinder?
If you need to step down from this 50 mm bore, the 40 mm neighbor provides 628 N of push force at 0.5 MPa and uses the same G1/4 port. If you require more power, the 63 mm bore offers 1558 N of push force at 0.5 MPa. Choose this MBLC model over the standard MBL when your application runs at higher speeds or shifts heavier loads that would prematurely wear out a fixed rubber bumper. Because this is a 175 mm stroke, side-load tolerance remains manageable, but the 16 mm rod still dictates careful alignment. Keep in mind that the adjustable air cushion only decelerates the piston near the ends; it is not a brake and will not hold the rod in place if air pressure is lost or the valve centers. For position holding without live air, an external rod lock is required. Replacement parts require a 50 mm bore, 175 mm stroke, PT thread, U flat-end back cover, and no magnet.
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 MBLC50X175U FAQ
At 0.5 MPa, this 50 mm bore cylinder provides 981 N of push force and 881 N of pull force. At 0.7 MPa, the push force is 1374 N. The theoretical maximum force is 200 kgf at 1.0 MPa.
A screw-tunable needle at both ends of the cylinder traps a small amount of exhaust air to decelerate the piston smoothly near the stroke ends. You adjust it to match your load and speed, which reduces impact, noise, and vibration compared to a fixed rubber bumper.
