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 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


Sky blue wiper seal:




1,Aging Resistant

2,Long Life

3,Phosphating Treatment

4,Very good wear resistance

5,Excellent dust proof effect

6,Easy installation

Technical parameter:
1,Working temperature: -30~ 110℃
2,Surface speed: ≤1.0m/s
3,Working medium: Hydraulic oils (mineral oil- -based)
Wiper Seal is a double lipped metal bonded wiper with sealing function. High prevention against dust,dirt, grains of sand and metal swarf.
This reduces the risk of scoring caused by contaminants from extemnal sources imbedded in the sliding parts.The excellent wiping effects is achieved bythe specical design of the wiper lip.

The wiper rings are manufactured with a slightly oversized outer diameter,thus ensuring a secure press fitin the groove after installtion. Any contact of the wiperlip with piston rod eyes or other connecting parts shouldbe avioded.

WR Wear Ring:


The function of Hydraulic wear ring is to guide the shaft and hole sealing of a hydraulic cylinder, absorbing transverse forces. At the same time, it previents metal-to-metal contact, optimizing the performance of the sealing system.

1. Good dimensional stability,can absorb stock

2. Uniform distribution of the large radial force

3. Low coefficient of friction,good sliding performance

4. Higher load bearing capacity

5. Excellent wear resistance

6. Wipe effect

7. Easy to install

8. Long service life
