The AirTAC Airtac MBLCJ Adjustable Mini Cylinder MBLCJ20X175-10S is a genuine double-acting aluminum-barrel mini cylinder with a Ø20mm bore, a 175mm nominal stroke and a rear adjustable-stroke stopper — trim up to 10mm for a usable window of 165–175mm. Adjustable air cushion (both ends).
The AirTAC MBLCJ20X175-10S is a compact, double-acting mini round cylinder with a single rod and a 20mm bore. It features a rear travel stopper allowing you to trim up to 10mm of motion, creating a precise 165-175mm usable stroke window. Tunable screw-in air cushions at both ends absorb impact energy, outperforming fixed rubber bumpers. Delivering 157N of push force at 0.5MPa, it suits delicate positioning tasks.
This model includes a built-in magnet (-S) for CMSG reed or DMSG/EMSG electronic sensors. The 8mm carbon-steel rod features 20µm hard-chrome plating to resist wear, while the heterogeneous two-way grease-retaining piston seal maintains lubrication. Remember the rear stopper sets the end position; it does not lock the load, and the cushion only decelerates. Mounting is limited to Basic, FA, or LB styles, as no back-cover or SDB pivot is available.

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 157N of push to hold PCB panels against routing spindles, using the 165-175mm stroke window to dial in exact cutting depths without overtravel.
Uses the tunable air cushion to softly retract the 8mm rod at high speed, preventing yarn snags while lifting thread packages from spindles.
Pushes lightweight plastic caps down an angled gravity chute, relying on the -S magnet and DMSG sensor to confirm full ejection before the next cycle.
Stepping down to the 20mm bore's smaller neighbour, the 12mm series, drops the 0.5MPa push force to about 90N, whereas moving up to a 25mm bore increases it to 245N. Choose this MBLCJ over the MBLJ for its tunable air cushions, which actively protect the end covers during fast 175mm travels. If your stroke length never changes, the fixed-stroke MBLC offers similar cushioning without the rear adjuster. For replacements, match the 20mm bore, 175mm stroke, 10mm adjust code, G1/8 port, default PT thread, Basic/FA/LB mounting, and the -S magnet. Because 175mm is a long stroke for an 8mm rod, use an external guide to prevent rod bending and premature seal wear.
Quick checklist
At 0.5MPa it provides 157N push and 132N pull. At 0.7MPa push increases to 220N. The theoretical maximum at 1.0MPa is 32kgf.
The rear 10mm adjuster acts as a travel stop, setting your usable stroke window to 165-175mm. The adjustable air cushion is a screw-tunable valve that decelerates the piston near the end caps. Neither holds the load; you need live air or an external lock for position holding.
