Key Specifications for KCS20-13.5 Series

• Manufacturer: KOBA (South Korea)

• Model: KCS20-13.5BN-W/O

• Type: Self-compensating (Constant orifice)

• Stroke: $13.5\text{ mm}$

• Thread Size: $M20\times 1.5$ (Standard for this series)

• Material: Nickel-plated body (indicated by the “N” in the model code) for corrosion resistance.

• Max Energy per Cycle: Approx. $30\text{–}40\text{ J}$ (Typical for M20 size)

• Max Energy per Hour: Approx. $35,000\text{–}45,000\text{ J/h}$

Features & Applications

• W/O Suffix: This often denotes “Without Cap” or “Without Stop Collar,” meaning the piston rod end is meant to interact directly with the machine part or a custom striker.

• Mounting: The fully threaded body allows for easy installation and precise positioning using lock nuts.

• Deceleration: Uses multiple internal orifices to provide a smooth, linear deceleration rather than a sudden stop.

• Common Uses:

  • Pick-and-place robotics.

  • Pneumatic cylinder end-of-stroke damping.

  • Packaging machinery and conveyor systems.

Installation Notes

1. Stop Collar: Since this model is often used without a built-in mechanical stop, ensure your machine has a hard stop $0.5\text{ mm}$ to $1\text{ mm}$ before the shock absorber bottoms out to prevent internal damage.

2. Heat Dissipation: If the cycle rate is very high, ensure the threaded body has good contact with a metal frame to help dissipate thermal energy.
