The AirTAC Airtac B01-MAC Series Special Purpose Cylinder B01-MAC20X210SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø0mm bore and 210mm stroke, PT/G air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service. A variable air cushion at both ends lets you tune end-of-stroke deceleration on site.
A 20 mm bore pushing a 210 mm stroke, the MAC20X210SCA is double acting with a variable air cushion at both ends, so end-of-stroke shock stays under control even at the top of the 30-800 mm/s speed range. At 0.5 MPa it delivers 157 N on extension and 131.9 N on retraction; at 0.7 MPa that climbs to 219.8 N. The CA pivot back cover swings on a pin, so linkage and lever jobs need no extra bracket.
The round stainless barrel and hard-chrome plated rod (20 um) shrug off mild corrosion, a real edge over painted-steel minis in damp or washdown corners. Plan on about 94 N of dependable working force at 0.5 MPa once you keep a margin, and treat this bore as lifting about 16 kg in theory - derate it to an 8 kg vertical payload for a 2:1 margin. The magnet comes built in, so CMSG, DMSG or EMSG switches drop straight on.

Specifications follow the official AirTAC MA-series datasheet. Barrel: stainless-steel tube (round-body, riveted rolling-packed construction); piston rod: carbon steel with 20µm hard-chrome plating; covers: aluminium alloy. Thread options: PT (blank) / G / NPT. Every MA-series cylinder ships with a built-in magnet for CMSG / DMSG / EMSG position sensors.

| Max (@1.0 MPa) | 0 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

MA-family variants: MA / MAC (double acting ±cushion), MSA / MTA (single acting push / pull), MAD / MACD (double rod ±cushion), MAJ / MACJ (adjustable stroke ±cushion), MAR (cushioned with integrated F/U mount). Mounting accessories: FA flange, LB foot, SDB pivot; plus I and Y knuckles. Thread PT (blank) / G / NPT.
The CA pivot cover pins straight into a swing clamp arm; 157 N at 0.5 MPa clamps aluminium brackets through the full 210 mm approach.
The rounded stainless barrel copes with washdown between shifts while the 210 mm stroke clears cartons off the belt edge.
Variable cushions let the gate run near 800 mm/s and still land softly, and the built-in magnet drives CMSG switches for open/closed confirmation.
Size against neighbours: bore 16 gives 100.5 N push at 0.5 MPa and bore 25 gives 245.3 N, so pick 20 mm when 100 N is thin and 245 N is overkill. A 210 mm stroke on an 8 mm rod wants external guiding if the load can tilt; side loads bend the rod and eat the seals. The CA pivot back cover suits pin-mounted linkages, with FA flange, LB foot or SDB pivot brackets for fixed frames. Note that the piston drifts to wherever the trapped air leaves it, so a rod lock or pilot check valve is the answer for held loads.
Quick checklist
At 0.5 MPa it pushes 157 N and pulls 131.9 N; at 0.7 MPa, 219.8 N push and 184.7 N pull. Theoretical maximum at 1.0 MPa is 32 kgf. The pressure window is 0.15-1.0 MPa (22-145 psi) and speed runs 30-800 mm/s.
The magnet is fitted as standard, so CMSG, DMSG or EMSG switches clamp onto the barrel for position signals. Air connects through 1/8" ports, with an M8x1.25 male rod thread for tooling.
