U-shaped Seal OKH Compact Piston Seals

OKH is a U-shaped seal, but because one seal can seal in both directions, it saves a lot of installation space. OKH has made improvements to anti-creeping. It has superior A5606, can use special low-temperature oil, and can be combined with anti-wear ring and retaining ring BRL type.

How To Keep In Stock For The Seal?

  • First, do not open the original packing to keep them clean to avoid any damage.
  • Second, should be stored away from direct sunlight and keep in low humidity environment. Sunlight and moisture make rubber get ageing asap, and get the size of rubber or plastic material changing.
  • Third, once it was opened, make sure there are no any other objects inside when repacked, and please kindly use the original packing bag.
  • Fourth, should be stored away from electric machinery which could be produced ozone.
  • At last, do not string up the seal and hang on the nail or metal wire, or the shape of seal get changing and damage the end of seal lip.
  • When the color of seal is changing or there is white powder(Frosting appears), there is no effect on the seal.


The Role Of The Seal:

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

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.

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.

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.
