The AirTAC Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X500SCA is a genuine double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 500mm stroke, G1/8 air ports and a fixed rubber bumper. Its compact riveted body suits push, hold and clamp motion in tight machine spaces.
The AirTAC MBLC25X500SCA is a double-acting aluminum mini cylinder engineered for a 500 mm stroke, delivering 245 N of push force and 206 N of pull force at 0.5 MPa. It features a built-in magnet (-S) for compatibility with CMSG reed and DMSG or EMSG solid-state sensor switches to track rod position. The CA pivot clevis back cover swings on a pin to accommodate arcing loads, which is critical for this maximum standard stroke length.
Unlike the base MBL series that relies on a fixed rubber bumper, this MBLC variant utilizes a screw-adjustable pneumatic air cushion at both ends. Tuning the cushion needle decelerates the piston smoothly near each stroke extremity, absorbing kinetic energy to protect the end covers on high-frequency or heavier moves. The riveted rolling-packed aluminum barrel keeps the body compact and lightweight, while the 20 µm hard-chrome plated carbon-steel rod resists wear alongside the heterogeneous two-way grease-retaining piston seal.

Drives the weft insertion guide on a rapier loom. The 500 mm stroke covers the full reed width, while the CA pivot absorbs the slight angular deflection of the guide rail and the air cushion prevents end-cover hammering during high-speed 800 mm/s cycling.
Actuates a deflector gate on a cut-to-length sawmill line. The 245 N push force at 0.5 MPa easily moves the wooden deflector, and the tunable cushion smoothly stops the 500 mm travel to prevent the heavy gate from slamming into the aluminum end covers.
Folds the top minor flaps on a random-case sealer. The 500 mm stroke reaches across wide cartons, and the integrated magnet allows a DMSG electronic sensor to trigger the glue gun precisely when the flap is fully extended.
At 0.5 MPa, this 25 mm bore generates 245 N push and 206 N pull. If your application requires less force, stepping down to the 20 mm bore yields 157 N push and 132 N pull. If you need to move a larger mass, stepping up to the 32 mm bore provides 402 N push and 346 N pull. Choose this MBLC model over the fixed-bumper MBL when your cycle speeds are high enough that impact deceleration is required to reduce noise and vibration.
Because this cylinder is configured with a 500 mm stroke, the 10 mm rod is highly susceptible to bending under side loads. The CA pivot back cover is specifically designed to swing on a pin for arcing or angular loads, but for rigid linear guidance over this long distance, you should add an external guide rail, use an SDB pivot bracket, or switch to an MBLD double-rod cylinder. The pneumatic 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 or the valve centers. Replacement parts require a 25 mm bore, 500 mm stroke, G1/8 port, PT thread, CA pivot cover, and an -S magnet.
Quick checklist
This 25 mm bore cylinder delivers 245 N push and 206 N pull at 0.5 MPa, and 343 N push at 0.7 MPa. The maximum theoretical force is 50 kgf at 1.0 MPa. The 500 mm stroke is the longest standard length available for this bore, with special order strokes available up to 800 mm.
The cushion is a screw-tunable needle valve at both ends that traps a pocket of exhaust air to decelerate the piston smoothly before it hits the end cover. Unlike a fixed rubber bumper that absorbs impact through collision, the air cushion allows you to tune the deceleration rate to match your specific load and speed, drastically reducing noise, vibration, and end-cover wear on fast cycles.
