Airtac B01-MFJ Dedicated Cylinder B01-MFJ32X30-10
The AirTAC Airtac B01-MFJ Dedicated Cylinder B01-MFJ32X30-10 is a genuine double acting, adjustable stroke JIS-standard round-body mini air cylinder with a Ø32mm bore and 30mm stroke, 1/4" air ports and a SUS304 stainless-steel barrel for mildly corrosive environments. For the same bore and stroke it is shorter than an ISO 6432 cylinder, saving mounting space.

About the Airtac B01-MFJ Dedicated Cylinder B01-MFJ32X30-10
The B01-MFJ32X30-10 is an AirTAC application-dedicated (customer-specified) variant of the standard MFJ32X30-10, sharing the exact same JIS-standard round-body construction and physical specs. Built with a SUS304 stainless barrel and riveted aluminium covers, this double-acting mini cylinder features an external adjuster that shortens the extend stroke by up to 10 mm on site, letting you dial in the end position without buying a new unit. The base 30 mm stroke yields a usable extend range of 20-30 mm, while retract remains full.
Delivering 402.2 N push and 345.6 N pull at 0.5 MPa (563 N / 483.8 N at 0.7 MPa), it fits mid-force tasks perfectly. The body is notably shorter than an ISO 6432 cylinder for the same 32 mm bore and 30 mm stroke, saving valuable mounting length. It uses fixed TPU bumper pads for end deceleration and a 1/4" port. Note that this SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG sensors.

Where the Airtac B01-MFJ Dedicated Cylinder B01-MFJ32X30-10 Is Used
Changeover Stations
Fine-tune the 20-30 mm extend position on site for product changeovers, using the 402.2 N push force to index parts without external stops.
Trial Fit Rigs
Dial in the exact end-of-stroke during prototyping; the external adjuster saves remounting a new cylinder when the target position shifts by a few millimetres.
Variable Position Stops
Set precise clamping limits within the 10 mm window, safely handling the 241 N working load while the SUS304 barrel resists mild washdown.
Is the Airtac B01-MFJ Dedicated Cylinder B01-MFJ32X30-10 the Right Cylinder?
When sizing this 32 mm bore, compare it directly against the MFJ40 and MFJ25. The MFJ40 provides a stronger 628.3 N push at 0.5 MPa if your payload demands more force, while the smaller MFJ25 offers 245.3 N for lighter duties. This MFJ32 strikes a balance, yielding a computed safe working load of roughly 241 N (about 60% of its 402.2 N push force) and lifting around 20.5 kg vertically with a 2:1 safety margin.
The 10 mm adjustable window is highly useful for trial fits, line changeovers, or setups where the exact end position is not yet final. Mounting options include LB foot, FA flange, and TC trunnion (no SDB or back-cover). Remember that the adjuster only sets the extend endpoint; it is not a mid-stroke lock. Because a plain cylinder drifts on air loss, add an external rod lock or pilot check valve if you need to hold a load safely.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/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/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac B01-MFJ Dedicated Cylinder B01-MFJ32X30-10 FAQ
This 32 mm bore cylinder has a 1/4" port and a 12 mm rod with an M10x1.25 male thread. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, 563 N push and 483.8 N pull at 0.7 MPa, with a theoretical max of 82 kgf at 1.0 MPa. The B01- prefix simply marks it as an application-dedicated variant of the MFJ32X30-10, mechanically identical to the base model.
The external adjuster shortens the extend stroke by up to 10 mm on site, giving a usable 20-30 mm range without changing the cylinder. It uses fixed TPU bumper pads to decelerate at the end of travel, not an adjustable air cushion. The cylinder cannot hold a load on air loss and will drift; use an external rod lock for holding. Also, this SKU lacks a magnet, so it cannot take CMSG/DMSG/EMSG sensors.
