About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X175-50
The AirTAC MBLCJ32X175-50 is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and an adjustable air cushion at both ends. The rear stopper allows you to trim up to 50 mm of travel, creating a usable stroke window of 125-175 mm for exact end-position tuning. Delivering 402 N of push force at 0.5 MPa, it is built for mid-range actuation tasks.
Unlike the fixed rubber bumper found on the base MBLJ, this model uses screw-tunable end-of-stroke cushioning to decelerate heavier loads smoothly and protect the end covers from impact shock. The riveted rolling-packed aluminum barrel and heterogeneous two-way grease-retaining piston seal minimize friction, while the Ø12 mm carbon-steel rod with 20 µm hard-chrome plating resists corrosion and wear. Note that this specific SKU lacks a built-in magnet, so it cannot support CMSG, DMSG, or EMSG position sensors.

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 MBLCJ32X175-50 Is Used
Textile Loom Weft Insertion
Uses the 125-175 mm adjustable stroke window to precisely time the weft insertion rake, while the air cushion absorbs the high-frequency 402 N deceleration impact without shaking the loom frame.
Circuit Board Stacking Lift
Tunes the exact lifting height of bare PCBs within a reflow oven loader, relying on the adjustable air cushion to softly park the 346 N pull load and prevent solder paste displacement.
Conveyor Pallet Stopper Gate
Acts as an end-of-line travel stop for incoming aluminum pallets, using the 50 mm rear adjuster to dial in the exact gate opening and the twin cushions to halt mid-range loads gently.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X175-50 the Right Cylinder?
When sizing this 32 mm bore actuator, consider stepping down to a 25 mm bore for lighter duties (offering 245 N push at 0.5 MPa) or stepping up to a 40 mm bore if your payload requires more thrust (628 N push at 0.5 MPa). The MBLCJ is preferred over the MBLJ when your moving mass demands tunable pneumatic deceleration rather than a fixed rubber bumper, or over the MBLC if you need on-the-fly stroke length trimming.
Remember that the rear adjuster is a travel stop, not a mechanical lock, and the air cushion only decelerates; neither will hold a load in place without live air pressure. Mounting is limited to Basic, FA (flange), or LB (foot) styles, as this series does not accept SDB pivot mounts or back-cover codes. To replace this unit exactly, match the 32 mm bore, 175 mm stroke, 50 mm adjust code, G1/8 PT port, and the absence of an -S magnet.
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 MBLCJ32X175-50 FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 346 N of pull force. At 0.7 MPa, the push force increases to 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa.
This specific SKU has no built-in magnet (-S omitted), so it cannot accept CMSG, DMSG, or EMSG position switches. The rear adjuster is a travel stop that sets the end position, not a lock, and the air cushion only decelerates; neither will hold a load statically without continuous air pressure.
