About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X80-75S
The AirTAC MBLCJ32X80-75S is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and an adjustable air cushion at both ends. It delivers 402 N of push force and 346 N of pull force at 0.5 MPa. The 75 mm rear trimmer creates a usable end-position window of 5 to 80 mm, letting you dial in the exact travel distance for a specific machine cycle. Equipped with a built-in magnet (-S), it supports CMSG reed and DMSG or EMSG solid-state sensor switches for precise position feedback.
This model distinguishes the rear travel stop from the end-of-stroke cushioning. The cushion needle valves tune deceleration to protect the end covers during fast moves, while the rear stopper physically sets the travel end. Neither mechanism locks the rod in place; a separate external guide or locking device is required to hold a load against drift. The riveted rolling-packed aluminum barrel and 20 µm hard-chrome plated carbon-steel rod handle operating pressures up to 1.0 MPa.

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 MBLCJ32X80-75S Is Used
PCB Router Z-Axis
Drives a 402 N spindle lift on a depaneling router, using the 5-80 mm window to set exact cutting depth without moving mechanical hard stops.
Bottle Capper Head
Applies precise 346 N pull force to press aluminum caps, relying on the adjustable air cushion to prevent slamming as the capping head descends at high speed.
Textile Yarn Guide
Traverses yarn guides across a winding drum, using the DMSG solid-state sensor to trigger rapid reversal exactly at the trimmed 5 mm minimum stroke endpoint.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X80-75S the Right Cylinder?
Stepping down to the 25 mm bore drops the 0.5 MPa push force to 245 N, whereas stepping up to the 40 mm bore raises it to 628 N. Choose this MBLCJ over the MBLJ when your application needs tunable end-of-stroke deceleration instead of a fixed rubber bumper, or over the MBLC when you need to trim the travel window rather than using a fixed stroke. The rear adjuster is a travel stop, not a load lock. Mounting is limited to Basic, FA flange, or LB foot brackets; no SDB pivot or back-cover options exist. For an exact replacement, match the 32 mm bore, 80 mm nominal stroke, 75 mm adjust code, G1/8 port, PT thread, and the -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 MBLCJ32X80-75S 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 is 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa.
The 75 mm rear adjuster mechanically trims the rod's travel end, creating a usable 5 to 80 mm stroke window. The adjustable air cushion is a needle valve that tunes end-of-stroke deceleration to prevent cover damage. The adjuster is a travel stop, not a lock; neither feature holds the load in place without live air.
