Truck parts Oil seal 1357776 Shaft seal For Scania P-/G-/R-/T-Series

Truck parts 1357776 Oil seal Shaft seal 32*100*122 For Scania 4-Series

The main factors causing oil seal leakage

Lack of oil seal is the main factor causing oil leakage. When the shaft wears and forms a groove, even if the oil seal is replaced with a new oil seal, the contact pressure between the oil seal lip and the shaft is decreased, resulting in too small interference between the oil seal lip diameter and the shaft diameter after installation.

Taking the S195 diesel engine crankshaft oil seal as an example, the main reasons for its lax seal are analyzed:

① The quality of oil seal manufacturing is poor;
② The shaft or bearing is of poor quality;
③ Improper use and maintenance;
④ Improper installation;
⑤ Improper storage, adversely affected by environmental pollution.

Advantage

1. The oil seal structure is simple and easy to manufacture. Simple oil seals can be molded once, and the manufacturing process is not complicated even for the most complicated oil seals. Metal frame oil seals can be formed into the required oil seals from metal and rubber only through the processes of stamping, gluing, inlaying, and molding.

2. The oil seal is light in weight and less consumable. Each 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, it is easy to process, and the machine is compact.

4. The 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. The oil seal is easy to disassemble and inspection is convenient.

6. The oil seal is cheap.
