Description:  This is a set of boom swing cylinder seal kit for Excavator KOMATSU.

Hydraulic cylinder seal kits are used to seal the gap between different parts of the hydraulic cylinder. Within the system, there are 2

main types of hydraulic seals :

Dynamic seals: Designed to seal various parts in relative motion. They can be utilized in high pressure and even when rod and hydraulic cylinder seals are in reciprocal motion between the head and the connecting rod.

Static seals: Our static seal kit seal parts that are not in relative motion. These are used in various loC-A-Tions as per the construction and look of the hydraulic cylinder. The connection rod and piston is the primary area where these seals are used.

Each of the dynamic seals confine a hydraulic cylinder, which contains a specific perform that contribute towards the system’s performance:

Rod seal: Acts a pressure barrier and helps the operational fluid inside of the cylinder to regulate the fluid film extending with the connecting rod’s surface. This is essential in inhibiting the corrosion of the rod and the lubriC-A-Tion of the wiper seal.

Piston seal: Acts as a barrier to the pressure and prevents the fluid from passing the piston. Necessary for maintaining the position when at rest or for the cylinder’s dominant motion.

Buffer seal: The rod seal is protected against fluid pressure peaks that can lead to fluctuating the system pressure with the help of buffer seals.
Wiper seal: It is designed to prevent external contaminants from coming inside the assembly of the cylinder.

(Rod and piston) functions: Prevents contact of metal-to-metal between parts, leading to keeping the piston and connecting rod accurately centered within the assembly of the cylinder. Helps in improving performance of the piston and rod waterproofing system.
