- Despite their seemingly small size, 35x50x8 oil seals have a significant impact on the overall performance and longevity of equipment. Their selection, installation, and maintenance must be done with precision to ensure optimal functionality. Regular inspection for signs of wear, damage, or leaks is crucial to prevent potential breakdowns and costly repairs.
Synthetic blend oil offers the best of both worlds. It has many of the characteristics of full synthetic oil, but at a much lower price. This type of oil is a mixture of synthetic and conventional base oils, plus some additives, for extra resistance to oxidation and excellent low-temperature properties. Synthetic blends make it easy for drivers to make the switch from conventional to synthetic oil, which is why this type of oil is becoming increasingly popular among today’s savviest drivers. It’s also a great middle ground for drivers who want the added protection and performance of a synthetic oil, but might not be ready to foot the bill for a total switch to full synthetic oil.
The quality of the rubber or rubber fabric used to make an outer case is the same as the quality of the rubber sealing lip. Fabric reinforced rubber is, as the name suggests, rubber reinforced with a fabric.
No. - Rubber or Elastomeric Sealing Lip: The sealing lip typically encloses the shaft in a tight seal formed of rubber or elastomeric material.
NBR, also known as nitrile rubber or nitrile, is the most popular material for an oil seal because of its good resistance to many oils and greases, such as mineral grease and hydraulic oil. Depending on their composition, synthetic oils and greases, such as those based on glycol, can damage NBR rubber materials. Depending on the amount of glycol, a PTFE lip seal may be the best choice. NBR is also unable to cope with contact with acids and solvents. The rubber is suitable for oil and grease at temperatures from -35 °C to 100 °C.
The temperature within the oil seal environment is the main factor that dictates the composition of an oil seal. Generally, there is a range of set temperatures that are optimal for that material. If the operating environment is too cold, the seal may become brittle and, at high temperatures, the seal material may show increased elasticity and become leaky.
Conventional oil seals are the traditional seals, which can be recognised by a spring on the inside. These oil seals are made of a metal housing that contains a rubber seal. This part is often made of elastomer and comes into contact with the surface of the rotating shaft.
JTEKT provides special seals for use in a wide variety of machines and applications.
Table 5 lists the major special seals, their shapes, and their features.
