High Sealing Performance 81808572 DC Oil Seal NBR Material Rotary Shaft Seal

Advantages Of Oil Seal:

1. Oil seal structure is simple and easy to manufacture. Simple oil seal can be molded in one time, even the most compliC.A.Ted oil seal, the manufacturing process is also oil seal not compliC.A.Ted. The metal skeleton oil seal can also form the required oil seal between metal and rubber only by stamping, gluing, inlaying, molding and other processes.

2. Oil seal has light weight and few consumables. Each type of oil seal is a combination of thin-walled metal parts and rubber parts, and its material consumption is very small, so the weight of each oil seal is very light.

3. The installation position of the oil seal is small, the axial size is small, easy to process, and make the machine compact.

4. Oil seal has good sealing performance and long service life. It has certain adaptability to the vibration of the machine and the eccentricity of the main shaft.

5. Oil seal is easy to disassemble and convenient for inspection.

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.
