different type balance shaft oil seal / different type oil seals for hydraulic

Introduction of different type oil seals

It is a kind of spare parts which are often applied to seal the oil, the other name of oil seal is swivel bearing lip-type packing.

As we know that there is some oil would go-in the rubbing parts of the machine usually and in order to resistant against this oil we need to use the oil seal to seal the gap of the machine. More than that, we have to concern to how to seal the water, chemical liquid and the dust, all of these environment calls for the oil seal.

Features of different type oil seals :
1).Excellent durability and flexibility in using.

2).Specially designed cords enhance durability and length stability.

3).Excellent in resistance against heat,oil and wear..

4).Show stable in high speed rotation.

5). Resistant to heat, oil, fatigue, aging and friction due to excellent and special frame

6). Large power, high speed, long service life, small distortion, less space occupying

Application of different type oil seals

1. Fluid system (static &dynamic), Hydraulic system (dynamic), Pneumatic system (dynamic), Oil or grease media sealing, Water media sealing.

2.Applied for electric motors, internal combustion engines and power transmission equipments.

3.Adopting scientific technical composition, specially selected first class rubber material (3M)and low elongation reinforcing.

4.Sanai rubber oil seal is in accordance with related international standard.

5. high wearing resistance, low elongation and long life.

Structure of different type oil seals

1. Material: NBR, SILICONE, VITON, HNBR, CR, PTFE, EPDM, etc. According to your requirement.
