The AirTAC Airtac MBLJ Adjustable Aluminum Alloy Mini Cylinder MBLJ63X150-50S is a genuine double-acting aluminum-barrel mini cylinder with a Ø63mm bore, a 150mm nominal stroke and a rear adjustable-stroke stopper — trim up to 50mm for a usable window of 100–150mm. Fixed rubber bumper.
The AirTAC MBLJ63X150-50S is a double-acting, single-rod aluminum mini cylinder featuring a rear adjustable stroke. It provides a usable extension window of 100 to 150 mm, letting you trim up to 50 mm of travel without external stops. At 0.5 MPa, it generates 1558 N of push force and 1457 N of pull force, making it well suited for high-load positioning tasks within a compact footprint.
This SKU includes a built-in magnet (-S) for compatibility with AirTAC CMSG reed and DMSG or EMSG electronic sensor switches. It uses a fixed rubber bumper to soften end-of-travel impact, while the riveted rolling-packed barrel and 20 µm hard-chrome plated carbon-steel rod ensure durability. The rear adjuster sets the end position but does not lock the load without live air pressure.

The rear stopper sets the end position — it is a travel stop, not a lock. Overall length = A + 2 × stroke + adjustable stroke. MBLJ/MBLCJ mounting is Basic / FA / LB only (no SDB, no back-cover code). Thread options: PT / G / NPT.

Actual usable force is lower than theoretical due to friction and back-pressure. Size with a margin.

Provides 1558 N of push force at 0.5 MPa to eject plastic parts, with the 100-150 mm window allowing quick retraction tuning for different mold depths.
Handles heavy cardboard flap folding with 1457 N pull force, using the 50 mm rear trim to synchronize the end position across varied box sizes.
Shifts heavy wooden pallets on a conveyor line, relying on the DMSG electronic sensor to confirm the 150 mm extended position for high-speed sorting.
If you need less force, stepping down to the 50 mm bore yields 981 N push at 0.5 MPa, whereas moving up is not an option as 63 mm is the largest MBLJ size. Choose this adjustable MBLJ over a fixed-stroke MBL when you need precise end-position tuning during product changeovers. If your application requires adjustable pneumatic cushioning rather than a fixed rubber bumper, consider the MBLCJ variant.
For a direct replacement, match the 63 mm bore, 150 mm stroke, 50 mm adjust code, G1/4 port, PT thread, and the -S magnet. Mounting is limited to Basic, FA, or LB; there is no back-cover or SDB pivot option. Because the adjuster is a travel stop and not a lock, use an external guide to support side loads and prevent rod bending.
Quick checklist
It delivers 1558 N push and 1457 N pull at 0.5 MPa, 2181 N push at 0.7 MPa, and a maximum theoretical force of 318 kgf at 1.0 MPa. It features a G1/4 port, a Ø16 mm rod, and an M14x1.5 rod-end thread.
The rear stopper allows you to shorten the stroke end position by up to 50 mm, creating a usable travel window from 100 to 150 mm. The adjuster acts only as a travel stop and does not hold the load without live air pressure.
