Airtac PTBR Single Acting Square Head Compact Cylinder PTBR16X60SR
The AirTAC Airtac PTBR Single Acting Square Head Compact Cylinder PTBR16X60SR is a single acting, pull type (spring extend) pen-size mini cylinder with direct front-cover mounting (M5×0.8 thread). A single air port drives the pull stroke on a Ø16mm bore, 60mm stroke; the return spring resets the rod when air is released.

About the Airtac PTBR Single Acting Square Head Compact Cylinder PTBR16X60SR
The AirTAC PTBR16X60SR is a JIS pen-size single-acting pull cylinder with a 16 mm bore and 60 mm stroke. Air entering the M5x0.8 port retracts the rod, while an internal spring pushes it back out, ensuring a fail-safe extended position on air loss. It delivers 65 N of net pull at 0.5 MPa and 101.2 N at the 0.7 MPa maximum, with the spring force already deducted.
You bolt directly to the fixture via the front-cover M5x0.8 thread, saving space in tight jigs. The SUS316L stainless barrel and Ø5 mm rod resist corrosion, while a fixed TPU bumper cushions the end of travel. This S variant includes a built-in magnet for reed or electronic position sensing.

| Stroke | 60 mm |
| Acting type | Single acting, pull type (spring extend) |
| Front-mount thread | M5×0.8 |
| Port size | M5×0.8 |
|---|---|
| Operating pressure | 0.2 – 0.7 MPa |
| Proof pressure | 1.2 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 50 – 800 mm/s |
| Return | Return spring (pull by air) |
| Max standard stroke | Up to 100 mm |
The spring holds the rod extended; applying air retracts it, and removing air lets the spring push the rod back out. Front cover carries the mounting thread (M5×0.8); barrel is SUS316L. Forces below are NET spring-deducted values. Confirm against the product label.
Net Pull Force (Ø16mm)
| Pressure | Net pull force |
|---|---|
| 0.5 MPa | 65.0 N |
| 0.7 MPa (max) | 101.2 N |
These are usable pull forces after the return spring is subtracted, from the AirTAC single-acting thrust table. Minimum operating pressure is set by the spring, so this model needs at least the lower pressure shown to move.

Where the Airtac PTBR Single Acting Square Head Compact Cylinder PTBR16X60SR Is Used
Hold-Down Clamping
Uses spring pressure to hold a workpiece extended, then air pulls the clamp back to release the part for automated unloading.
Retract-to-Open Gate
Keeps a sorting lane gate closed by default and pulls it open on signal, returning to the closed state if pneumatic pressure drops.
Web Tensioner
Maintains steady outward tension on a filament or web, retracting the guide roller to slacken the line during machine setup.
Is the Airtac PTBR Single Acting Square Head Compact Cylinder PTBR16X60SR the Right Cylinder?
This 16 mm bore provides 65 N net pull at 0.5 MPa. If you need less force, the 12 mm bore offers 33.1 N; stepping up is not possible as 16 mm is the largest in the series. Plan for a safe working load of about 39 N, which is roughly 60 percent of the rated figure, to account for seal friction and smooth travel.
The fail-safe extended design keeps the rod out during pressure loss, making it ideal for hold-down or return-to-home tasks. Remember the thin Ø5 mm rod is for coaxial thrust only; over this 60 mm stroke, add an external guide or linear bearing to prevent side-load damage. Confirm your M5x0.8 front-mount thread engagement and axial R back-cover inlet plumbing before ordering.
Quick checklist
- ✓ Net pull force at your working pressure
- ✓ Bolt directly through the front cover (M5×0.8)
- ✓ Only one air line / solenoid needed
- ✓ Fail-safe extend on air loss
- ✓ Magnet (S) for sensors?
- ✓ Stroke ≤ 100 mm (single-acting limit)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.2 – 0.7 MPa operating pressure.
- check Allow for spring force in the stroke direction.
- check Match bolt size and engagement to the front thread.
- check Do not add an external return mechanism.
- check Keep the load coaxial; avoid side load on the thin rod.
Airtac PTBR Single Acting Square Head Compact Cylinder PTBR16X60SR FAQ
It provides a net pull of 65 N at 0.5 MPa and 101.2 N at the 0.7 MPa maximum. The internal spring requires a minimum 0.2 MPa to move the rod, and the cylinder fails safe to the extended position on air loss.
It mounts directly via the M5x0.8 front-cover thread. The S option includes a built-in piston magnet compatible with AirTAC reed or electronic switches, and the SUS316L stainless barrel suits corrosive environments.
