Rubber Seals

Rubber Seals

Rubber seals are used in hydraulic machines to prevent leakage and to keep out contaminants. In order to prevent wear from friction, hydraulic machines have a gap between the rotating shaft and the housing. Rubber seals are used in order to prevent hydraulic fluid from leaking from this gap.

Rubber seals can be used as oil seals, lip seals, or mechanical seals. Oil seals can be fitted with a single or double lip. Double lip oil rings are designed to prevent corrosion and to keep out dirt and dust. Some oil seals are spring-loaded to maintain contact between the seal lip and the shaft. Lip seals, in comparison, are versatile, high-performance seals used for uniform, low-pressure applications. Finally, mechanical seals are intended for applications in which a rotating shaft and its housing are under a state of extreme stress, including a combination of high pressure, temperature, and speed.

Rubber seals are used to join mechanisms together in order to prevent leakage and to aid in compression. Rubber seals can be made of a variety of natural and synthetic rubber products and can be reinforced with metal cores. The metal case provides rigidity and strength to the seal.

Rubber seals can be used in many other applications, in addition to their role in hydraulic machines. Some of the industries that use rubber seals include automobile, appliance control, lawn and garden, sporting goods, medical, electrical, government, and recreational.
