AirTAC Pneumatics
AirTAC mini air cylinders: 33 series covering 8-63 mm bores with 20032 published part numbers, in double-acting and spring-return push or pull types across stainless, round and aluminium bodies.
inventory_220090 models availableThis is the entry point to the AirTAC mini cylinder family: 33 small round-body series, 20032 published part numbers, bores from 8 to 63 mm. Every code follows the same grammar - M for mini, a body-type letter, an action letter, then combinable suffixes - so once you can read the letters you can find your own part. MI is a plain stainless double-acting mini; MIC adds adjustable cushions at both ends; MIJ adds an on-site adjustable extend stroke; MICJ has both; MSI and MTI are the single-acting push and pull versions.
Body types split by bore and material. The I branch (stainless round body, 8-40 mm) is the only one reaching 8 mm bore. The A branch (round body, 16-63 mm) includes MA at 100-628 N and MAR at 157-1558 N with an integrated F/U mounting bracket, both at 0.5 MPa. The BL branch (riveted aluminium barrel, 20-63 mm) spans 157-1558 N at 0.5 MPa. The F and G branches are JIS SUS304 stainless - MF bodies are shorter than ISO 6432 - with MG offering a fixed bumper pad from 20-40 mm and MGC variable cushions across 20-63 mm.
Action matters most. S series are single-acting push: air extends the rod and a spring retracts it, so the safe state on air loss is retracted. T series are single-acting pull: the spring extends the rod, so the safe state is extended. Both are described as spring return, but they move in opposite directions when air is lost - the easiest detail to order wrong. Note that the whole AL aluminium-barrel branch (MAL, MALJ, MSAL, MTAL) is discontinued; the BL branch is the replacement, and legacy codes remain quotable for maintenance.
Fast short-stroke transfers suit the cushioned double-acting minis: MIC, MAC or MBLC add adjustable cushions at both ends, and MBLCJ lets commissioning trim the extend stroke on site across 20-63 mm bores.
Where a workpiece must release if air is lost, a single-acting push series is the right tool: MSI (8-40 mm stainless), MSF (JIS SUS304, stroke to 150 mm) or MSA (60-440 N at 0.5 MPa) extends on air and springs back retracted.
When air loss must leave the rod out - blocking a conveyor lane or holding a gate open - the single-acting pull series fit: MTI (8-40 mm), MTA (stroke to 100 mm) or MTG with 85-339 N pull force.
The stainless I branch reaches down to 8 mm bore, the smallest in the family, while MF and MG offer JIS SUS304 bodies - MF deliberately shorter than ISO 6432 - for tight JIS-style machine layouts.
Start with what happens on air loss: nothing held means double-acting; the rod must retract means an S series such as MSI, MSA, MSBL, MSF or MSG; the rod must extend means a T series such as MTI, MTA, MTBL, MTF or MTG. Then pick the bore branch: 8-40 mm needs the I branch (the only ones going to 8 mm); 16-63 mm the A branch; 20-63 mm the BL or G branch; 20-40 mm the F branch. Add C for adjustable cushions at both ends if the move is fast or the load is heavy; a fixed bumper pad on MA or MG is enough for light duty. Add J for an adjustable extend stroke if end positions will be trimmed during commissioning - the J and C versions carry most of the volume, with MBLCJ, MIJ, MICJ, MBLJ and MFCJ each near or above 800 part numbers. Confirm the 5-point match: bore, stroke, port/thread, mounting style, and magnet option (MA and MAC list a built-in magnet as standard; for other series confirm the magnet at order time).
Step outside this family when the constraint is not diameter: compact cylinders when axial length matters, standard cylinders above 63 mm bore, guided cylinders when the rod must not rotate. The cylinder sensor family, mounting brackets and rod ends sit under cylinder accessories. Replacing an old MAL, MALJ, MSAL or MTAL? Quote the BL-branch replacement (MBL, MBLJ, MSBL, MTBL) and we confirm equivalence on the specific code.
Quick checklist
Bores run from 8 to 63 mm across 33 series and 20032 published part numbers. Force at 0.5 MPa spans 100-628 N for MA, 157-1558 N for MAR and MBL, 60-440 N for single-acting push MSA, 110-440 N for MSG and 85-339 N pull for MTG. Smaller-bores forces for other series: confirm from the datasheet.
MSI is single-acting push: air extends, the spring retracts, so the rod retracts on air loss. MTI is single-acting pull: the spring extends, so the rod extends on air loss. Among double-acting versions, MI is plain, MIC adds adjustable air cushions at both ends for fast or heavy moves, MIJ adds an adjustable extend stroke, and MICJ combines both. The same pattern applies to the A, BL, F and G body branches.
The AL aluminium-barrel branch is discontinued. MAL maps to MBL, MALJ to MBLJ, MSAL to MSBL and MTAL to MTBL. The legacy codes stay listed and quotable for machines in the field, but for new builds specify the BL replacement and we confirm the match on the exact code, bore and mounting.
No series here is claimed as ISO 6432 compliant - the JIS SUS304 MF series is described only as shorter than ISO 6432, so specify by AirTAC code. Everything listed is genuine AirTAC and orderable; the catalogue shows no live quantity, so lead time is confirmed on request when you send the full part number.
