Festo Cylinder DSNU-20-100-PPS-A

⚙️ Main Product Series – Function & Application Comparison

🌟 Detailed Description of Key Product Series

1. Standard Cylinders

• DSBC series – One of Festo’s flagship standard cylinders. Hard‑chromium plated piston rod, service life up to 5,000 km of reciprocating travel. Equipped with intelligent PPS self‑adjusting pneumatic cushioning – automatically adjusts end‑speed and reduces impact force by up to 70%, significantly extending equipment life and lowering noise. Compliant with ISO 15552, bore sizes from 8 to 320 mm, high output force – up to 50 kN thrust at 6 bar.

• DSNU series – Basic double‑acting standard cylinder, compact and ISO 15552 certified, high reliability. Bore sizes from 8 to 25 mm, suitable for small to medium automation tasks.

2. Compact Cylinders

• ADN/AEN series – Compact double‑acting cylinders conforming to ISO 21287. Known for small size and high dynamic response. Bore sizes from 6 mm to 25 mm, stroke typically ≤100 mm, weight only about 0.1 kg (ADN-20-10). Requires up to 50% less space compared with ISO 15552 cylinders. Numerous variants; sensor grooves on three sides allow flush mounting of proximity switches. Integrated cushioning pads absorb residual energy, excellent cushioning characteristics, very low friction coefficient, long service life.

• ADN-S series – Integral compact housing, further reduced diameter and height, designed for extremely tight spaces.

• ADVU series – Even shorter than ADN, suitable for ultra‑compact spaces.

• AEN-S series – Ultra‑micro cylinder with only 10 mm bore and 5 mm stroke, weight approx. 17 g, even uses no cushioning – ideal for precise actuation of very small movements, such as clamping small workpieces or extending/retracting inspection probes.

3. Rodless Cylinders & Guide Cylinders

• DFM series – Guide cylinders, combining a linear cylinder with a precision guide mechanism (square or rectangular guide rods). High rigidity, torque resistance, and precise guidance. The guide rods effectively absorb lateral forces, reduce piston rod bending stress, and improve motion stability. Twin guide rod version handles loads up to 200 kg.

• SLT series – Magnetically coupled rodless cylinder, bore 10‑50 mm. No mechanical connection; equal push and pull piston areas make precise intermediate positioning easy. The external slider has no dynamic seal, effectively avoiding external leakage. No external leakage risk, stroke up to 3 m.

• DGC series – Slide cylinder with integrated linear guide, suitable for high‑precision linear motion, enabling precise handling and assembly.

4. Rotary / Swing Cylinders

• DRD series – Rack‑and‑pinion swing cylinder, rotation angle 0‑270°. The rack‑and‑pinion design ensures constant torque over the entire swing range, avoiding the torque decay of traditional vane‑type cylinders.

• CRDNU series – Compact rotary cylinder, torque ≤10 Nm, suitable for precise angular swinging in compact spaces.

5. Special‑Environment Cylinders

• HFT series – High‑temperature cylinders, operating temperature range -20°C to +150°C, suitable for high‑temperature applications.

• OEN series – Stainless steel cylinders, excellent corrosion resistance, suitable for food, chemical, outdoor or mildly corrosive environments.

• EX series – Explosion‑proof cylinders, ATEX certified, suitable for potentially explosive working environments.

• ADN‑S6 series – Cleanroom cylinders, compliant with ISO Class 5 cleanliness, suitable for clean environments in semiconductor and pharmaceutical industries.
