4411535 Hydraulic Oil Seal fits Swing Device Transmission HITACHI ZH200-A
 
Description: The hydraulic oil seal is in contact with the rotating shaft at a certain pressure with its narrow sealing contact surface (less than

0.5mm), and seals under the action of liquid lubrication. As an elastomer seal, the cross-sectional shape of the hydraulic oil seal and the

tightening spring enable the lip to have a better follow-up compensation performance to the shaft, so that a good sealing effect can be obtained

with a small radial force of the lip.

The Working Principle of Hydraulic Oil Seal:

1. In the free state, the inner diameter of the oil seal lip is smaller than the shaft diameter and has an interference.

2. After installation, the interference pressure of the edge of the hydraulic oil seal and the contraction force of the self-tightening spring produce a

certain radial pressure on the rotating shaft.

3. When working, the oil seal lip forms a sealing contact ring with a width of 0.25 to 0.5 mm under the action of radial pressure. Under the action

of lubricating oil pressure, the oil penetrates into the hydraulic oil seal blade and the shaft to form a thin oil film. The oil film is affected by the

surface tension of the oil, forming a "crescent" surface on the outer edge of the shaft and the oil seal cutting edge to prevent the oil from

overflowing and play a sealing role.
