The AirTAC Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X500-10 is a genuine double-acting aluminum-barrel mini cylinder with a Ø40mm bore, a 500mm nominal stroke and a rear adjustable-stroke stopper — trim up to 10mm for a usable window of 490–500mm. Adjustable air cushion (both ends).
The AirTAC MBLCJ40X500-10 is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and a tunable air cushion at both ends. It delivers 628 N of push force and 528 N of pull force at 0.5 MPa. The rear stopper allows you to trim up to 10 mm of travel, creating a usable 490-500 mm stroke window to dial in exact end positions. Because this unit lacks the -S magnet code, it cannot accept a CMSG, DMSG, or EMSG position sensor.
Twin screw-adjustable cushions absorb kinetic energy near the stroke ends, protecting the end covers during these long 500 mm travels far better than a fixed rubber bumper. The riveted rolling-packed barrel and 20 µm hard-chrome plated carbon-steel rod resist wear, while the heterogeneous two-way grease-retaining piston seal maintains lubrication. Note that the rear adjuster sets the travel end and the cushion only decelerates; neither mechanism locks the load in place.

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.

Regulates fabric tension on a weaving loom. The 628 N push force maintains steady beam tension, while the 490-500 mm window allows exact alignment of the let-off mechanism.
Pushes veneer sheets onto a stacking platform. The tunable air cushion prevents harsh impacts at the end of the 500 mm extension, protecting both the wood sheets and the cylinder end covers.
Actuates a folding gate on a corrugated box machine. The 10 mm rear stroke trim perfectly sets the folding dead-stop, ensuring consistent carton creases without needing sensor feedback.
For applications needing less force, the 32 mm bore offers 402 N push at 0.5 MPa; if you need more power, the 50 mm bore provides 981 N. This MBLCJ variant is chosen over the MBLJ when a fixed bumper cannot survive high-speed 500 mm strokes, and over the MBLC when you need that 490-500 mm fine-tuning window. The overall length equals A + 2 x 500 + 10 mm, and mounting is limited to Basic, FA, or LB styles (no SDB or back-cover options exist).
Because this stroke reaches the 500 mm maximum standard limit for a 40 mm bore, the small 16 mm rod is highly susceptible to side-load bending. An external guide is mandatory to prevent rod damage. For exact replacements, match the 40 mm bore, 500 mm stroke, 10 mm adjust code, G1/4 port, PT thread, and confirm no magnet is present. The adjuster acts as a travel stop, not a brake, so external mechanical locking is required to hold a load.
Quick checklist
It has a 40 mm bore and a G1/4 port. At 0.5 MPa it pushes 628 N and pulls 528 N. At 0.7 MPa it pushes 880 N, with a maximum theoretical force of 128 kgf at 1.0 MPa.
No. This SKU lacks the -S magnet, so it cannot mount a CMSG, DMSG, or EMSG sensor. Additionally, the rear adjuster is only a travel stop and the air cushion only decelerates; neither acts as a lock, so an external mechanical lock is required to hold a load.
