Dark blue SKF rod seal:
The reinforced structure design is insensitive to the slight damage of piston rod and sealing groove and will not leak.
The diameter of the product is in the middle of the design, the dynamic performance in the groove is good, easy to install.
U - 1023 polyurethane material has a wide working temperature range, the limit temperature range is-60 °C to 130 °C, and the long-term temperature range is 30 °C to 110°C.
The product has a star ring, which ensures the precompression and shrinkage of the seal lip under the condition of high and low pressure, and improves the reliability of the seal. Good sealing performance can be achieved even in low temperature working environment.
Disposable injection molding technology, does not need to go through the secondary trimming, the size is more accurate, the performance is superior.

Dark blue TecThane DKB:


  1. Thickened skeleton design, the product strength is higher, installed in the groove is more stable, not easy to deform.
  2. The spraying treatment of skeleton surface can prevent rust on the surface of skeleton very well.
  3. Reasonable design of dustproof lip height, not only to provide reasonable dustproof ability, but also to follow the sloshing produced by piston rod operation.
  4. Adopt high performance polyurethane material, wear resistance, aging resistance, long service life.
  5. The sealing lip is designed to unload the oil hole to prevent the formation of pressure between the dustproof and the main oil seal, resulting in the extrusion of the dustproof ring and the reverse compression damage of the main oil seal.
  6. Reasonable dust-proof lip wall thickness design, that is, to provide enough dust-proof force, but also to maintain the oil film on the piston rod.

  7. Reasonable dustproof R angle design, that is, has a good dust scraping effect, and does not hang up the oil film on the piston rod to form dripping.


Dark blue SKF HBY:


  • Choose polyurethane material to have the ability of high temperature resistance.
  • WIth Polyurethane material, buffer seal has high strength and impact resistance.
  • The matching ring has high strength and strong extrusion resistance.
  • The matching ring size is reasonable and easy to install, which avoids the installation problems and use problems caused by the size or size of the matching ring. And it is not easy to absorb water and expand, resulting in size changes
  • Perfect structural design, good oil return characteristics, avoiding pressure


Piston rod seal all use dark blue three-piece set, the life of the system is about 6 times longer than that of ordinary domestic products.
