About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X500-100S
The AirTAC MBLCJ40X500-100S is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and an adjustable air cushion at both ends. It delivers 628 N push and 528 N pull force at 0.5 MPa through a G1/4 port. The 100 mm rear trimmer creates a usable travel window of 400 to 500 mm, letting you dial in the exact extended position for a 500 mm stroke without machining spacers.
Unlike the base MBLJ which relies on a fixed rubber bumper, this model uses screw-tunable end-of-stroke cushioning to decelerate heavy 880 N (at 0.7 MPa) moves smoothly. The riveted rolling-packed barrel and 20 um hard-chrome plated carbon-steel rod handle speeds up to 800 mm/s. The built-in magnet (-S) supports CMSG reed and DMSG/EMSG electronic sensors for position feedback. Note that the rear stopper sets the travel end but does not hold the load, and the cushion only decelerates; neither acts as a mechanical lock.

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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 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 MBLCJ40X500-100S Is Used
CNC Pallet Transfer
Provides 628 N of push force to index heavy machining pallets along a 500 mm stroke, using the adjustable cushion to stop the 880 N moving mass smoothly without shock.
Long-Stroke Gripper Actuation
Extends a large robotic gripper across a 400 to 500 mm usable window, allowing precise rear-position tuning for varied part sizes while the magnet confirms full extension.
Packaging Pusher Assembly
Drives heavy carton pushers in a packaging line, relying on the tunable air cushion to decelerate the 500 mm travel at high speed, preventing end-cover damage during rapid cycling.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X500-100S the Right Cylinder?
For lower force requirements, stepping down to a 32 mm bore yields 402 N push at 0.5 MPa, while moving up to a 50 mm bore provides 981 N if your payload exceeds 628 N. Choose this MBLCJ over an MBLJ when your 500 mm travel speed requires tuned pneumatic deceleration to protect the end covers rather than a fixed bumper. Choose an MBLC if you need fixed 500 mm travel without the rear adjustment mechanism. Because the overall length equals A + 2 x stroke + adjust, verify your mounting envelope. Mounting is limited to Basic, FA flange, or LB foot styles; no back-cover or SDB pivot is available. At 500 mm stroke, the 16 mm rod is highly susceptible to side loading—always use an external guide rail to prevent rod bending. To replace this unit, match the 40 mm bore, 500 mm stroke, 100 mm adjust code, PT thread, and -S magnet. The adjuster is a travel stop, not a lock; use an external locking device if the load must be held without live air.
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 MBLCJ40X500-100S FAQ
At 0.5 MPa it provides 628 N push and 528 N pull. At 0.7 MPa the push force is 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa operating pressure.
The 100 mm rear adjuster acts as a travel stop, creating a usable 400 to 500 mm extension window. The adjustable air cushion is separate; it uses a needle valve to tune end-of-stroke deceleration. Neither the stopper nor the cushion locks the load in place.
