About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X80-50
The AirTAC MBLCJ32X80-50 is a compact double-acting aluminum mini cylinder featuring a rear travel stopper and tunable end-of-stroke deceleration. The rear adjuster allows you to trim up to 50mm of travel, creating a usable stroke window of 30-80mm. Driven by a Ø12mm hard-chrome plated carbon-steel rod, it generates 402N of push force and 346N of pull force at 0.5 MPa. The riveted rolling-packed aluminum barrel and heterogeneous two-way grease-retaining piston seal ensure consistent lubrication for high-speed actuation up to 800 mm/s.
Unlike the base MBLJ which relies on a fixed rubber bumper, this SKU utilizes screw-tunable adjustable air cushions at both ends to absorb kinetic energy, protecting the end covers during fast 80mm moves. This specific configuration uses a standard PT (tapered) port thread and lacks a built-in magnet, meaning it cannot support CMSG, DMSG, or EMSG position sensors. The rear stopper sets your exact end position, while the cushion manages deceleration—neither component acts as a mechanical lock to hold a suspended load.

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.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |

| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a margin.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X80-50 Is Used
Packaging Sealing Head
Drives a 32mm sealing jaw with 402N push force at 0.5 MPa, using the 30-80mm adjustable window to dial in exact package widths while the air cushion prevents end-cover impact during fast cycling.
PCB Conveyor Diverter
Actuates a routing gate at 30-800 mm/s speeds; the tunable cushion decelerates the 80mm stroke smoothly to protect fragile circuit boards from sudden jolts at the travel end.
Textile Loom Tensioner
Regulates yarn tension guides using the 346N pull force, relying on the grease-retaining seal and riveted barrel for continuous operation in high-vibration fabric weaving environments.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X80-50 the Right Cylinder?
Stepping down to the 25mm bore yields 245N push at 0.5 MPa, whereas moving up to the 40mm bore provides 628N, giving you a clear upgrade path if this 32mm unit's thrust is insufficient. Choose the MBLCJ over the fixed-stroke MBLC when a machine format change requires varying the end position, or over the MBLJ when cycle speeds demand hydraulic-like deceleration instead of a fixed rubber bumper. Remember that the rear adjuster is a travel stop, not a clamp; if the application requires true position holding without continuous air supply, an external locking device is necessary. Mounting is limited to Basic, FA flange, or LB foot styles as this series omits SDB pivot and back-cover options. For a direct replacement, match the 32mm bore, 80mm stroke, 50mm adjust code, G1/8 port, PT thread, and no-magnet configuration.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Adjustable window fits your end position
- ✓ Adjuster is a travel stop, not a lock
- ✓ Magnet (S) for sensors?
- ✓ Side load — add a guide on long strokes
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Set the rear stopper for the end position (a travel stop, not a lock).
- check Avoid side load; add an external guide on long strokes.
- check Mounting: Basic / FA flange / LB foot (no SDB, no back-cover code).
- check Installation by qualified personnel per AirTAC docs.
Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X80-50 FAQ
At 0.5 MPa, the 32mm bore generates 402N of push force and 346N of pull force. At 0.7 MPa, the push force increases to 563N. The maximum theoretical force is 82 kgf at 1.0 MPa.
This specific SKU lacks the -S code for a built-in magnet, so it cannot support CMSG, DMSG, or EMSG position switches. The 50mm adjustment code is a rear travel stopper that sets your usable stroke window between 30mm and 80mm, while the adjustable air cushion is a separate screw that tunes end-of-stroke deceleration; neither mechanism locks the load.
