Product Description

DAQ

DAQ seals are designed for fast-speed and high-pressure working conditions where pressure retention is necessary. They are recommended for use in double-acting pistons, piston-type energy storage systems, supporting cylinders, and positional cylinders. These seals offer double safety with low friction and high elasticity, providing excellent dynamic and static sealing performance. They can accommodate larger extrusion clearances while effectively holding pressure, resulting in minimal leakage in hydraulic cylinders. With a simple groove design and small installation space, they exhibit excellent sliding performance and are free from crawling phenomenon.



Design Description:
The DAQ piston seal is a double-acting seal, with a PTFE sealing ring and a Quard ring responsible for dynamic sealing, while an O-ring provides static sealing.

Applications :
It is widely used in equipment such as machine tools, presses, accumulators, stabilizers, and heavy-duty suspension cylinders.

Technical Specification:
Pressure: 40 MPa
Speed: 2 m/s
Temperature: -30°C to +200°C (depending on the elastomeric material)
Medium: All common hydraulic oils, including bio-oils and gases.
Clearance: The maximum allowable radial clearance (emax) depends on the working pressure and functional diameter.

Materials:
Sealing ring: filled polytetrafluoroethylene (F-PTFE)
O-ring: nitrile rubber (NBR) or fluoroelastomer (FKM)
Quard ring: nitrile rubber (NBR) or fluoroelastomer (FKM)

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 .

Recommended Shelf Life :
