Airtac B01-MI Dedicated Pneumatic Cylinder B01-MI20X200SU
The AirTAC Airtac B01-MI Dedicated Pneumatic Cylinder B01-MI20X200SU is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 200mm stroke, 1/8" air ports and a stainless-steel barrel and rod for mildly corrosive environments. Its ISO 6432 mounting interface makes it a compact drop-in for standard mini-cylinder fixtures.

About the Airtac B01-MI Dedicated Pneumatic Cylinder B01-MI20X200SU
Generating 157 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles a 200 mm stroke with a stainless-steel barrel and rod that resist mild corrosion in damp or washdown environments. The B01- prefix designates an application-dedicated, customer-specified variant of the standard MI20X200SU, meaning the core mechanics, 1/8 inch port, and M8x1.25 male rod thread remain completely identical to the base model. Fixed TPU bumper pads absorb the impact at stroke extremes, and because the piston pushes with roughly 94 N of usable work at 0.5 MPa, it lifts about 8 kg vertically with a safe two-to-one margin.
The Ø20 mm bore conforms to ISO 6432 mounting dimensions, allowing it to drop directly into standard mini-cylinder brackets and clevises. This specific configuration includes a U-type back cover for 90-degree port orientation and an internal piston magnet for position sensing. A plain double-acting cylinder drifts if air pressure drops, so an external rod lock or pilot check valve is required if you need to hold a load securely mid-stroke.

Where the Airtac B01-MI Dedicated Pneumatic Cylinder B01-MI20X200SU Is Used
Package Diverting Gate
Actuates a routing flap on a packaging line, using the 157 N thrust to push parcels smoothly onto secondary belts.
Vertical Parts Lift
Raises lightweight 8 kg fixtures between machine tiers, leveraging the 200 mm stroke and stainless rod for washdown durability.
Pneumatic Clamp Station
Secures aluminum extrusions during machining operations, relying on the U-type back cover for flexible 90-degree mounting.
Is the Airtac B01-MI Dedicated Pneumatic Cylinder B01-MI20X200SU the Right Cylinder?
When sizing this 200 mm stroke model, compare the thrust classes: the smaller Ø16 bore provides 100.5 N of push at 0.5 MPa, while the larger Ø25 bore steps up to 245.3 N. This Ø20 delivers a balanced 157 N, making it ideal for medium-duty positioning. For a 200 mm extension, side-load and rod-bending forces are a real factor, so ensure the load is guided to prevent premature seal wear. The built-in magnet supports CMSG, DMSG, or EMSG switches for end-of-stroke confirmation. If your cycle speed creates excessive end-impact, consider the MIC variant which offers adjustable air cushioning instead of the standard fixed TPU bumpers.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check Use correct back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac B01-MI Dedicated Pneumatic Cylinder B01-MI20X200SU FAQ
At 0.5 MPa it provides 157 N push and 131.9 N pull. At 0.7 MPa it provides 219.8 N push and 184.7 N pull. The theoretical maximum force is 32 kgf at 1.0 MPa. The air port size is 1/8 inch.
The B01- prefix indicates an application-dedicated, customer-specified variant of the standard MI20X200SU, mechanically identical to the base cylinder. It uses fixed TPU bumper pads to decelerate the stroke end, not an adjustable air cushion. It includes a magnet for CMSG/DMSG/EMSG sensors and follows ISO 6432 mounting dimensions.
