Product Description

HBY
HBY combined with rod seals, to absorb impact and surge pressure under heavy load in order to separate high temperature fluids and improve the service life of the seal element.
The main functions of the buffer seal in the hydraulic system include several aspects. First, it buffers the shock pressure or pressure fluctuations produced by the piston rod of the hydraulic cylinder, easing the backpressure. Second, the seal helps cooling down the temperature, prevents the overheat from transmitting to the seal, and reducing heat generated from the piston rod seal during operation. Third, it reduces the friction resistance caused by the piston rod seal in the hydraulic cylinder. In general, the buffer seal provides adequate lubrication to the piston rod seal or other main seals, and it can enhance the gap extrusion resistance. Thereby, it can extend the durability of the seal element.

Sealing Component Storage Guidelines and Recommend-ed Shelf Life
Storage Recommendations:
Stock Control Follow the First- In-First-Out (FIFO) princip le
Optimal Temp. Seals should be kept aw ay from heat sources like direct sunlight and heat-emitting objects . The
maximum storage temperature is +32°C. Low temperatures w on't cause permanent damage to
the seals but can make them brittle, leading to potential breakage if mishandled. Generally , the
storage temperature for seals should not go below +10°C, and they should be brought to room
temperature before installation.
Avoid strong
light
Surfaces should be shielded from direct sunlight and artificial light sources to prevent exposure
to ultraviolet radiation.
Moisture
control
Special care should be taken during storage, and the ambient humidity should not exceed 65% .
Some specific polyurethane seals that are sensitive to moisture should be stored in sealed
containers
Keep away
from oxygen
and ozone
Ozone and oxygen are harmful to seals . Seals should be stored in sealed containers . Any
equipment that generates sparks should be kept aw ay from the storage containers .
Keep away
from
For seals to have a longer storage life, they should be kept aw ay from contaminants . The
w arehouse should be kept clean.
Avoid
distortion
Large seals should be stored flat instead of hanging, as prolonged hanging can cause
distortion. Seals should not be placed on hooks , nails , or metal plates .
