- d. Fluorocarbon Rubber (FKM) – is widely known under the Chemours (formerly Dupont™) trade name of Viton® and offers the best resistance to chemicals and superior performance to high temperatures.
- Why are sealed bearings favored over the unsealed alternative? Why ought sealed ball bearings be preferred to unsealed ones? What advantages can sealed ball bearings offer?
- Despite their robust construction, head gaskets can fail due to various reasons, including overheating, excessive cylinder pressure, or simply age and wear. A blown head gasket, a condition where the gasket fails, can result in severe engine damage, such as coolant leakage into the oil, loss of compression, or even complete engine seizure. Therefore, regular maintenance and prompt attention to any signs of gasket failure, like coolant in the oil or white smoke from the exhaust, are crucial.
- Improper use of sealants.
- By following these steps, you can easily change the spark plugs in your vehicle and keep it running efficiently. It is recommended to change the spark plugs every 30,000 to 50,000 miles, or as recommended by your vehicle manufacturer. Remember, regular maintenance is key to prolonging the life of your vehicle and preventing costly repairs down the road.
3. Dust and debris are common reasons for oil seal failure.

tc oil sealing. Whether it is used in a small engine or a large industrial system, TC oil seals can be customized to fit the specific needs and requirements of the machinery. This level of customization ensures that the seals provide a secure and reliable barrier against leaks, even in harsh operating conditions.
Regular inspection and replacement of oil seals are also necessary to prevent leakage and maintain the efficiency of the machinery. Over time, oil seals can wear out due to constant friction and exposure to harsh conditions, leading to leaks and potential damage to the equipment. By monitoring the condition of oil seals and replacing them as needed, operators can prevent costly downtime and repairs.

3. Dust and debris are common reasons for oil seal failure.
The edge of the metal is finely ground after seal manufacture in a centerless grinder to enable an interference fit in the oil seal housing. A slight chamfer on the outer diameter (OD) of the seal is desirable for easy assembly. The sealing lip is prepared by buffing, grinding or cutting away the rubber flash which occurs at the sealing edge. A fine sealing edge creates sufficient pressure on the shaft to minimise spring load, leading to lower friction whilst maintaining effective seal performance. The garter spring plays an important role in the efficiency of the oil seal. If its tension is too high, heat will be generated between the sealing lip and the shaft, and result in rapid wear of the lip. If too low, the spring will be ineffective and the sealing lip will be worn away leading to leakage of the fluid.
Over time, piston oil seals may wear out or become damaged due to normal wear and tear, extreme temperatures, or poor maintenance practices. When this happens, oil leakage can occur, leading to decreased engine performance and potential damage to the engine.
