The AirTAC Airtac MBLJ Adjustable Mini Cylinders MBLJ32X50-10 is a genuine double-acting aluminum-barrel mini cylinder with a Ø32mm bore, a 50mm nominal stroke and a rear adjustable-stroke stopper — trim up to 10mm for a usable window of 40–50mm. Fixed rubber bumper.
The AirTAC MBLJ32X50-10 is a compact double-acting aluminum mini cylinder with a rear adjustable-stroke stopper. The -10 code means you can trim up to 10 mm off the rear end position, giving a usable stroke window of 40-50 mm - set the exact end stop at commissioning or during product changeover without swapping the cylinder or bolting on external stops.
The riveted rolling-packed barrel keeps the body short and light for tight machine frames, but note the overall length is longer than a plain MBL because it follows A + 2 x stroke + adjustable stroke. The rod is 12 mm carbon steel with 20 um hard-chrome plating on an M10x1.25 thread, and the air port is G1/8 with a PT tapered thread form as standard. Cushioning is a fixed rubber bumper only - if you need an adjustable air cushion, that is the MBLCJ variant. This SKU carries no -S magnet, so it cannot accept a CMSG, DMSG or EMSG position sensor.

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.

| Max (@1.0 MPa) | 70 kgf | |
MBLJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative), lower than a single-rod MBL push of the same bore. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a margin.

A 50 mm stroke pushes finished housings off a mold face with 402 N at 0.5 MPa, while the 10 mm rear trim lets the toolmaker dial the ejector park position back to 40 mm so parts clear the stripper plate cleanly.
Stopping 5 kg cartons on a packaging line infeed sits well inside the 346 N pull capacity; when the carton pitch changes, the 40-50 mm window is re-set at the rear screw instead of re-plumbing or replacing the cylinder.
Pressing dowel pins into small brackets needs a controlled short advance - the adjuster limits the end of travel between 40 and 50 mm, and the fixed rubber bumper softens the seat without an air-cushion circuit.
Choose MBLJ over the fixed-stroke MBL when the end position must be fine-tuned on the machine, and over MBLCJ when you do not need an adjustable air cushion (MBLJ keeps the fixed rubber bumper). Remember the rear adjuster is a travel stop, not a load lock - with no live air the rod will drift, so use an external device where holding is required. Mounting is Basic, FA flange or LB foot only; there is no SDB pivot and no back-cover option on MBLJ. For a like-for-like replacement match bore 32, stroke 50, adjust code 10, G1/8 PT port, mounting and the absence of the -S magnet.
Quick checklist
The theoretical maximum is 82 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa (proof 1.5 MPa) with a 30-800 mm/s speed range, and the 12 mm hard-chrome rod carries an M10x1.25 end thread.
The -10 code is the amount of travel you can trim at the rear stopper, so the usable window is 40-50 mm on this 50 mm cylinder. The adjuster is a travel stop, not a lock - it sets the end position but does not hold the load without live air. Note this SKU has no -S magnet, so no CMSG, DMSG or EMSG sensor can be fitted.
