Airtac MBLJ Adjustable Aluminum Alloy Mini Cylinder MBLJ25X225-10S

The AirTAC MBLJ25X225-10S is a compact double-acting aluminum mini cylinder featuring a rear travel stopper that trims the rod extension. You can fine-tune the end position within a 215-225 mm usable window without bolting on external stops. Driven by a Ø10 mm hard-chrome rod, it delivers 245 N push and 206 N pull at 0.5 MPa, making it well-suited for mid-distance positioning tasks.

This SKU includes a built-in magnet (-S) for CMSG reed or DMSG/EMSG electronic sensors. It relies on a fixed rubber bumper to soften end impacts, while the riveted rolling-packed barrel and grease-retaining piston seal ensure consistent friction. Remember the rear adjuster only sets the travel limit; it does not lock the load without continuous air pressure.

When sizing this actuator, consider stepping down to a Ø20 bore for lighter 157 N tasks or up to a Ø32 bore if you need 402 N push force. This MBLJ variant offers the 10 mm rear trim advantage over a fixed-stroke MBL, but for high kinetic energy, the MBLCJ provides an adjustable air cushion instead of the standard rubber bumper. The overall length is longer than a plain MBL due to the adjuster housing, and mounting is restricted to Basic, FA, or LB styles—no SDB or back-cover options exist. For a direct replacement, match the 25 mm bore, 225 mm stroke, 10 mm adjust code, G1/8 PT port, and the -S magnet. Because the stroke is 225 mm, an external guide is recommended to prevent rod bending under side loads.
