About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X20-10S
The AirTAC MBLCJ32X20-10S is a compact double-acting mini cylinder featuring a Ø12 mm hard-chrome plated rod and a built-in magnet. It delivers 402 N of push force at 0.5 MPa, making it well-suited for high-impact short-stroke tasks. A rear mechanical adjuster allows you to trim the nominal 20 mm stroke down by 10 mm, creating a precise 10-20 mm usable travel window.
Unlike the standard MBLJ bumper, this model incorporates a screw-tunable air cushion at both ends to decelerate the piston near the stroke extremes. The riveted aluminum barrel and grease-retaining piston seal ensure consistent friction. Remember that the rear stopper sets the travel end position but does not lock the load in place; external guidance is still required to absorb lateral stresses.

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 MBLCJ32X20-10S Is Used
PCB Edge Guiding
Uses the 10-20 mm fine-tuned stroke window to nudge circuit boards into exact alignment on an SMT conveyor without overshooting.
Light Staking Press
Leverages the 402 N push force and tunable air cushion to seat small rivets smoothly, avoiding the harsh impact of a fixed bumper.
Pneumatic Ejector
Deploys the -S magnet with an EMSG solid-state switch to trigger rapid ejection of small plastic parts from a mold cavity.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X20-10S the Right Cylinder?
For applications needing less force, the Ø25 bore offers 245 N at 0.5 MPa, while stepping up to the Ø40 bore provides 628 N for heavier pushing. The defining advantage of this MBLCJ over the MBLJ is the adjustable air cushion, which absorbs kinetic energy to protect the end covers during rapid cycles. The rear stroke adjuster and the cushion valves regulate travel length and deceleration respectively, but neither component acts as a mechanical brake to hold a load without continuous air pressure.
When ordering a replacement, verify the 32 mm bore, 20 mm stroke, 10 mm adjust code, G1/8 port, and PT thread form. This SKU includes the -S magnet for position sensing and supports Basic, FA, or LB mounting. Because the overall length equals A + 2 x stroke + adjust, confirm your spatial envelope before installation.
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 MBLCJ32X20-10S 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 1.0 MPa.
The rear adjuster lets you trim the travel by 10 mm, providing a usable 10-20 mm window. This acts strictly as a travel stop and does not lock or hold the load. The separate adjustable air cushion only controls end-of-stroke deceleration.
