The P1F-L in bore sizes Ø32 to 125mm is an ISO 15552 linear pneumatic cylinder for standard temperature (-20 to +80°C) with an integrated air/spring dynamic rod lock allowing the piston rod to be braked or locked in any position. Incorporating a powerful piston rod locking device, which clamps the piston rod and locks it in position. The locking device is a spring lock with an air pressure release and is mounted to the front plate of the cylinder. In the absence of an air signal pressure, full holding force is applied to the piston rod. When air is present at a certain minimum pressure the locking device is released.

The piston rod lock can be used in all material handling systems where controlled fastening or positioning is required. The piston rod lock is also suitable for use as a pressure-loss brake for cylinders with suspended loads.

The P1F-L rod lock cylinder is available for cylinder bores Ø32 to 125mm. The design provides several valuable characteristics, such as:
• A high holding force.
• The front plate and locking device are built into a common block for compact installation.
• Exhaust air from the locking device can be piped away from when there are demands for a contamination free environment.
The design is easy to clean, sealed and waterproof. The exhaust air from the lock unit can be removed by replacing the filter unit with a connector and hose. This is an advantage in terms of cleaning or when environmental factors are important.

Like all P1F cylinders this series is supported by a full range of ISO mountings, sensors and is suitable for wide range of general typical industrial applications. Note that these units are not certified for use in safety systems.

General Technical Data:
• International Standard: complies with ISO 15552 (corresponds to the withdrawn standards ISO 6431, DIN ISO 6431, VDMA 24562, NFE 49003.1 and UNI 10290) for installation dimensions except WH which smaller and not in accordance with ISO.
• Bore Sizes : Ø32, 40, 50, 63, 80, 100 and 125 mm
• Stroke Length : 5 to 2000mm
• Versions : double acting / double acting with through rod
• Cushioning : adjustable pneumatic
• Position Sensing : "Drop in" or “Straight in” sensors can easily be installed in two recessed grooves located on one face mechanically protecting the sensor that can be located at any position along the piston stroke. Choose between electronic or reed sensors with various cable lengths and M8 knurled screws or flying lead connection.
• Installation : a wide range of cylinder mountings in aluminum providing the same overall corrosion resistance.
• Mounting Position : any

Operating and Environmental Data:
• Operating Medium : for best possible service life and trouble-free operation dry, filtered compressed air to ISO 8573-1:2010 quality class 3.4.3 should be used. This specifies a dew point of +3°C for indoor operation (a lower dew point should be selected for minus temperature operation and we recommend the use of an inline dryer) and is in line with the air quality from most standard compressors with a standard filter.
• Operating Pressure : > 4 to 10 bar
• Brake Release Pressure : > 4 bar (Signal pressure to inlet port in the lock unit)
• Operating Temperature : standard temperature -20 to +80°C
• Pre-lubricated : further lubrication is normally not necessary. If additional lubrication is introduced it must be continued.
• Corrosion Resistance : high resistance to corrosion and chemicals. Materials and surface treatment have been selected for industrial applications where solvents and detergents are frequently used.
