About the AirTAC MACJ20
The AirTAC MACJ20 is a double-rod, double-acting stainless-steel mini cylinder with adjustable cushions with a 20 mm bore and an 8 mm piston rod. The rod runs through both end covers, so push and pull are equal: 132 N at 0.5 MPa and 185 N at 0.7 MPa. The rear rod end carries the stroke adjuster: the travel can be shortened by up to the adjustment amount in the code (10-100 mm across the codes on this page). Force depends on bore and pressure only, so every stroke on this page gives the same output.
All MACJ20 versions share 1/8" air ports, an M8×1.25 rod thread and adjustable air cushions at both ends. The cylinder runs on filtered air between 0.15 and 1.0 MPa (proof 1.5 MPa), from -20 to +70 °C, at 30 to 800 mm/s. This page lists 107 stock order codes with strokes from 10 to 300 mm; the catalog maximum stroke is 300 mm.

Theoretical output force (Ø20 mm)
| Pressure | Push | Pull |
|---|---|---|
| 0.5 MPa | 132 N | 132 N |
| 0.7 MPa | 185 N | 185 N |
Both directions act on the bore area minus the Ø8 mm rod area, because the rod passes through both end covers. Usable force is lower because of friction and back-pressure.
How the MACJ20 Order Code Is Built

Where the MACJ20 Is Used
Small pushers and stoppers
About 132 N at 0.5 MPa suits light pushers, stoppers, gates and ejectors.
Packaging and assembly
Compact strokes for feeders, diverters and assembly stations.
Sensed positioning
Magnet versions report stroke ends to the PLC through cylinder sensors.
Choosing the Right MACJ20 Configuration
Start with the stroke. Pick the exact travel your machine needs; a longer stroke adds length, weight and air consumption without adding force. If your length is not listed, request a quote and we will confirm whether it can be built.
Then the stroke adjustment (10-100 mm): pick the amount by which you need to trim the stroke on the machine. The cylinder can be set anywhere between full stroke and full stroke minus that amount.
Then choose the mounting. Basic (no code) uses the cylinder's own mounting holes. This bore is stocked with LB foot bracket. Foot and flange mountings hold the cylinder rigid for straight-line loads; clevis and trunnion mountings let it pivot when the load moves in an arc.
Finally pick the version: S adds a magnet for position sensors.
AirTAC MACJ20 FAQ
No. Every MACJ20 gives about 132 N in both directions at 0.5 MPa, whatever the stroke.
The number after the dash is the adjustable range in mm. An MACJ20X100-50, for example, can be set to any stroke between 50 and 100 mm.
1/8" ports, PT thread as standard.
Brackets: LB foot bracket. Pick a pivoting cover or bracket when the load moves in an arc, a rigid one for straight-line loads.
Usually yes. Request a quote with the stroke, mounting and version and we will confirm whether it can be built, plus price and lead time.
0.15 to 1.0 MPa operating pressure (proof 1.5 MPa) and -20 to +70 °C on filtered air.
No. You can order a single MACJ20. Orders are processed and handed to the carrier within 3-5 business days.
