About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X500SU
The AirTAC MBLC25X500SU is a double-acting, adjustable-air-cushion mini cylinder engineered for compact linear motion. A 25 mm bore yields 245 N push and 206 N pull at 0.5 MPa, making it suitable for mid-range actuation across a long 500 mm stroke. The riveted rolling-packed aluminum barrel keeps the body light and tight for machine integration, while the 20 µm hard-chrome carbon-steel rod resists wear against the heterogeneous two-way grease-retaining piston seal.
This SKU ships with a U flat-end back cover for rigid mounting and a built-in magnet (-S) for CMSG, DMSG, or EMSG sensor switches. Because the piston travels 500 mm on a 10 mm rod, side-load tolerance is low; an external guide rail is strongly recommended to prevent rod bending and premature seal failure over this maximum standard length.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X500SU Is Used
Packaging Lane Diverter
Sorts cartons along a 500 mm stroke where the adjustable air cushion prevents harsh snapping at full extension, protecting the U flat-end cover during continuous high-speed routing.
Textile Loom Guide
Shifts a yarn guide carriage across a wide loom bed; the 245 N push force handles the carriage drag while the cushion needle dials out vibration at 500 mm endpoints.
Pallet Push-Off Arm
Stages empty pallets into a wrapping station; the built-in -S magnet tracks arm position via a DMSG electronic sensor, and the cushion softens the 500 mm full-thrust stop.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X500SU the Right Cylinder?
At 0.5 MPa, this 25 mm bore generates 245 N of push force. If your payload is lighter, stepping down to the 20 mm bore drops output to 157 N but saves space. If you need to move heavier masses, the 32 mm bore jumps to 402 N. Choose this MBLC version over the base MBL when cycling speeds are high or the payload is heavy enough that a fixed rubber bumper cannot absorb the end-of-stroke impact. The screw-tunable air cushion decelerates the piston smoothly near each end, but it is not a load lock; the rod will drift if air is lost or the valve centers. Use an external rod lock or pilot-operated check valve for position holding without live air. Replacement match: 25 mm bore, 500 mm stroke, G1/8 port, PT thread, U flat-end back cover, magnet included.

- ✓ 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 MBLC25X500SU FAQ
At 0.5 MPa, this 25 mm bore cylinder provides 245 N of push force and 206 N of pull force. At 0.7 MPa, push increases to 343 N. The maximum theoretical force is 50 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 500 mm stroke endpoints. You tune the needle to match load and speed, which cuts end-cover impact and noise. It only decelerates near the ends and does not lock the load.
