Frequently Asked Questions - ESNU-63-25-P-A Festo
What is the ESNU-63-25-P-A?
The ESNU-63-25-P-A is a Festo pneumatic cylinder with a 63 mm bore and 25 mm stroke. It is a compact double-acting linear actuator used to produce pushing and pulling motion in automated machines.
What does the model number ESNU-63-25-P-A mean?
ESNU identifies the Festo cylinder series; 63 denotes the piston diameter in millimetres; 25 is the stroke length in millimetres; P generally indicates the piston rod configuration and A the standard variant. For exact interface dimensions, refer to the Festo datasheet.
What air pressure should I use?
The recommended operating pressure range is 1 to 10 bar. Many applications use 6 bar as a standard supply pressure to achieve the nominal force. Always stay within the maximum pressure indicated in the manual to avoid damaging seals or end caps.
How much force can the cylinder produce?
With a 63 mm bore and a supply pressure of 6 bar, the theoretical advance force is approximately 1870 N. The retract force is slightly lower because the piston rod reduces the effective area on the return stroke.
Does the cylinder require lubrication?
The cylinder can operate with filtered, unlubricated compressed air. If oil has been added to the system, lubrication must be maintained permanently; otherwise, the seals may dry out and wear more rapidly.
How do I install the cylinder?
Mount the cylinder on a flat surface using the available threaded holes or optional mounting accessories. Align the piston rod with the load direction to avoid side forces, then connect the two pneumatic ports to a directional control valve.
What is the allowed operating temperature?
The standard version is designed for an ambient temperature range of about -20 °C to +80 °C. For extreme temperatures, check the detailed ordering data or use a cylinder with special seal material.
How should I clean and maintain it?
Keep the piston rod clean and slightly coated with a suitable grease if needed. Wipe the outside with a damp, lint-free cloth and avoid aggressive solvents. Check the rod bearing and seals regularly, and replace damaged parts before leaks appear.
Are spare parts available and is it repairable?
Yes, Festo offers service kits with seals and wipers for this type of cylinder. The piston rod and other components can be replaced by qualified staff. Disconnect the air supply and depressurise the system before any repair.
