About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X50-30S
The AirTAC MBLCJ32X50-30S is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and an adjustable air cushion at both ends. The 30mm adjuster allows you to trim the rear travel, creating a usable end-position window of 20 to 50 mm. Driven by a Ø12 mm carbon-steel rod with 20 µm hard-chrome plating, it delivers 402 N of push force and 346 N of pull force at 0.5 MPa. The built-in magnet (-S) supports CMSG, DMSG, and EMSG sensor switches for position detection.
This model separates travel stopping from end-of-stroke deceleration. The rear adjuster acts as a mechanical stop to set the exact end position, while the screw-tunable air cushion regulates the speed of the piston near the covers to prevent impact damage. Unlike the fixed rubber bumper found on the MBLJ series, this adjustable cushion allows you to optimize deceleration for varying loads. The riveted rolling-packed barrel and heterogeneous two-way grease-retaining piston seal maintain consistent lubrication over a 30-800 mm/s speed range.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X50-30S Is Used
PCB Drill Stroke Trimming
Uses the 20-50 mm adjustable window to fine-tune the exact plunge depth of a 402 N drill head, while the tunable air cushion prevents end-cap shock during rapid retraction.
Textile Loom Tensioning
Adjusts fabric guide positioning dynamically, leveraging the DMSG electronic sensor feedback and the 346 N pull force to maintain consistent material tension.
Small Parts Ejector
Employs the 30 mm rear stopper to shorten the ejection stroke from 50 mm to 20 mm, keeping the 12 mm rod clear of the main conveyor mechanism while cushioning the return.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X50-30S the Right Cylinder?
Stepping down to the 25 mm bore reduces the output to 245 N push at 0.5 MPa, which may be insufficient for heavier mid-stroke loads, while stepping up to the 40 mm bore increases the force to 628 N if your payload exceeds the 402 N rating of this 32 mm unit. Choose the MBLCJ over the MBLJ when your application requires tunable deceleration rather than a fixed bumper, or over the MBLC when you need to fine-tune the end position rather than using a fixed stroke. The G1/8 port and PT thread form are standard for this bore size.
When ordering a replacement, verify the 32 mm bore, 50 mm stroke, 30 mm adjust code, PT thread, and the -S magnet. Mounting is limited to Basic, FA (flange), or LB (foot); this series does not offer a back-cover or SDB pivot option. The rear adjuster sets the travel end and the cushion decelerates the load, but neither component mechanically locks the rod or holds position without continuous air pressure.
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 MBLCJ32X50-30S FAQ
At 0.5 MPa, the push force is 402 N and the pull force is 346 N. At 0.7 MPa, the push force increases to 563 N. The maximum theoretical force is 82 kgf at the 1.0 MPa pressure limit.
The 30 mm adjustable stroke is a rear mechanical stopper that physically limits the travel window to 20-50 mm, setting the exact end position. The adjustable air cushion is a screw-tunable valve that regulates exhaust flow to decelerate the piston near the end covers. Neither feature locks or holds the load in place without live air pressure.
