AirTAC PBJ Series Adjustable Pen-Size Cylinders
The AirTAC PBJ series is an adjustable-stroke, double-acting pen-size mini cylinder offered in 10, 12 and 16 mm bores, built for slim actuators that must trim their forward end position on site.
inventory_2247 models availableSeries Overview
The PBJ series is AirTAC's adjustable-stroke version of the PB JIS pen-size mini cylinder. It features a slim pen-diameter stainless steel barrel and a double-acting design. The extend stroke is trimmed on site via an adjusting screw, allowing precise forward end-position tuning without changing the actuator.
The range spans three bores: 10, 12 and 16 mm. Maximum operating pressure is 0.7 MPa. Push force at 0.5 MPa is modest (tens of Newtons) and scales with the bore, with theoretical maxima reached at the 0.7 MPa ceiling. Buyers should size from the specific model figure rather than assuming a fixed series output.
Shared design elements include a fixed TPU bumper that decelerates the piston near stroke end (it does not lock or hold position) and small pen-size ports with a direct front-cover mounting thread. The PBJ is a pen-size mini cylinder, not a tie-rod, ISO 6432 or ISO 15552 cylinder. A magnet -S option is available for switch sensing. Use PBJ where a slim actuator must trim its forward end position on site; for fixed stroke use PB, for single-acting push use PSB, and for a double rod use PBD.

Typical Applications
Small part clamping in electronics assembly
The 10 and 12 mm bores provide low-profile clamping on PCBs and connectors, while the on-site adjusting screw dials in the exact forward position to avoid crushing delicate components.
Thin film and foil positioning
A slim pen-diameter stainless barrel fits into tight packaging guides, and the adjustable extend stroke lets operators fine-tune the push distance for varying film widths without swapping cylinders.
Lab automation sample routing
The 16 mm bore offers higher push force for moving small sample racks, while the -S magnet option enables precise end-of-stroke confirmation for automated test sequences.
How to Choose the Right Model
Choose within the PBJ series by matching the bore to your load: 10 and 12 mm bores suit very light pick-and-place, while the 16 mm bore provides higher push force at the 0.7 MPa ceiling. Select the magnet -S option if you need position sensing. Confirm these five points before ordering: bore size, required adjustable extend stroke, pen-size port and front-cover mounting thread, mounting style, and magnet -S option.
Step out of the PBJ series if you need a fixed stroke (use PB), a single-acting push action (use PSB), or a double rod to resist rotation (use PBD). Because the PBJ uses a fixed TPU bumper for deceleration only, it will not hold position if air pressure is lost; a mechanical lock or pilot check valve is required for load holding.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and available mounting space
- ✓ Port / thread type (PT / NPT / G)
- ✓ Sensor / magnet option (-S)?
- ✓ Side load — consider a guided model
Frequently Asked Questions
The PBJ series spans 10, 12 and 16 mm bores. It is a double-acting cylinder where push force is greater than pull force. At 0.5 MPa the push force is modest (tens of Newtons) and scales with the bore, reaching theoretical maxima at the 0.7 MPa pressure ceiling. Always size from the specific model figure.
The PBJ is the adjustable-stroke version, using an adjusting screw to trim the extend stroke on site. The PB is the fixed-stroke version, the PSB is single-acting push, and the PBD is a double-rod version. Use the PBJ specifically when a slim actuator must have its forward end position trimmed in the field.
No. The PBJ is a pen-size mini cylinder, not a tie-rod, ISO 6432 or ISO 15552 cylinder. It features a stainless barrel, small pen-size ports and a direct front-cover mounting thread. Do not specify it as a drop-in ISO replacement.
No. The PBJ uses a fixed TPU bumper that decelerates the piston near the stroke end, but it does not act as a lock, brake or hold. Being a double-acting air cylinder, it cannot hold position if pressure is lost. A mechanical lock, rod brake or pilot check valve is required for load holding.
