NBR 0734319718 Wheel Hub Shaft Seal 0734-319-718 High Pressure Truck Oil Seal

Basic information:

Oil seal is often called grease, fluid, dirt or lip seals. Oil seal is an integral part in any rotating and moving part assembly. They close spaces between stationary and moving components in mechanical equipment. In most appliC.A.Tions, the seal is either partially or temporarily immersed or is simply exposed to splashing lubricant, particularly in engines, transmissions, gearboxes or axles. They are vital components of almost every type of machine and vehicle in operation. An oil seal normally consists of three basic components: The Sealing Element (the nitrile rubber part), the Metal Case, and the Spring. It is a widely used sealing component. The function of a seal is to prevent the leakage of medium along the moving parts.

Measures For Oil Leakage Due To Inadequate Oil Seal:

1. Master and recognize the basic knowledge of fake and inferior products, and purchase high-quality and standard oil seals.

2. During installation, if the roughness of the outer surface of the shaft diameter is low or there are defects such as rust, burrs, etc., smooth it with a fine emery cloth or whetstone; apply clean engine oil or grease to the lip of the oil seal or the corresponding position of the shaft diameter. Apply sealant to the outer ring of the oil seal, wrap the key way on the shaft with hard paper to avoid scratching the lip of the oil seal, and use a special tool to rotate and press the oil seal inwards. Do not smash the hard seal to prevent deformation of the oil seal or squeeze the spring and fail; If there is lip cuffing, the spring falls off and the oil seal is skewed, It must be removed and reinstalled. It should be noted that when the shaft diameter is not worn and the spring force of the oil seal spring is sufficient, do not tighten the inner spring without authorization.

3. The oil seals applied to machinery generally have to be inspected, maintained and maintained when the general working conditions are poor, the ambient temperature difference is large, the dust is excessive, and the vibration of the machine tool frequently changes the stress condition of the machine parts.

4. If the shaft diameter and bearing are seriously worn; The rubber seal oil is aging or the spring is invalid, etc., repair and replace the corresponding parts in time.
