About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X75-50
The AirTAC MBLCJ32X75-50 is a compact double-acting mini cylinder featuring a 32mm bore and a 75mm stroke. It generates 402N of push force and 346N of pull force at 0.5MPa. A rear stroke adjuster allows you to trim up to 50mm of travel, providing a usable stroke window of 25-75mm for precise end-position tuning. This configuration uses a G1/8 port, a Ø12mm rod, and PT threads. Because this specific SKU lacks the -S suffix, it has no internal magnet and cannot support position sensing.
Unlike the base MBLJ which relies on a fixed rubber bumper, this model features an adjustable air cushion at both ends. You can screw-tune the end-of-stroke deceleration to handle heavier moving loads smoothly, protecting the end covers from impact. The riveted rolling-packed aluminum barrel and grease-retaining piston seal ensure reliable operation, while the 20um hard-chrome plating on the carbon-steel rod resists wear. Note the rear stopper sets the travel limit and the cushion regulates speed; neither component acts as a mechanical lock to hold a load in place.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X75-50 Is Used
PCB Router Z-Axis
Provides 402N of push force for a printed circuit board routing spindle, using the 25-75mm stroke window to set exact cutting depth and the air cushion to prevent jarring stops.
Label Dispenser Tamp
Drives a tamp pad in a packaging line, relying on the 50mm rear adjuster to tune label placement height without repositioning cylinder mounts.
Textile Loom Tensioner
Actuates a fabric tensioning lever in a textile loom, using the dual end cushions to decelerate the 75mm stroke smoothly and protect yarn guides from sudden impacts.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X75-50 the Right Cylinder?
Select this 32mm bore when you need 402N of push force at 0.5MPa combined with a highly adjustable stroke window. If your application requires less force, stepping down to the 25mm bore provides 245N of push force. If you need significantly more power, stepping up to the 40mm bore yields 628N. The defining advantage of this MBLCJ over an MBLJ is the tunable air cushion, which absorbs kinetic energy at the stroke ends far better than a fixed bumper. Compared to an MBLC, you gain the 50mm rear travel adjuster to dial in the exact 25-75mm usable window.
When ordering a replacement, verify the 32mm bore, 75mm stroke, 50mm adjust code, G1/8 port, PT thread form, and the lack of a magnet (no -S). Mounting is limited to Basic, FA flange, or LB foot styles; this series does not support SDB pivots or back-cover codes. The overall length equals A + 2 x stroke + adjust, so plan your envelope accordingly. Because the cushion only decelerates and the adjuster is merely a stop, use an external locking mechanism if the load must be held rigidly in place against pressure variations.
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 MBLCJ32X75-50 FAQ
At 0.5MPa, this 32mm bore cylinder provides 402N of push force and 346N of pull force. At 0.7MPa, the push force increases to 563N. The maximum theoretical force is 82kgf at 1.0MPa.
No, this specific SKU (MBLCJ32X75-50) does not have the -S suffix, meaning it lacks a built-in magnet and cannot be used with AirTAC CMSG, DMSG, or EMSG position switches. You would need to order the -S variant to support reed or electronic sensing.
