D-образное уплотнительное кольцо (Внутренний диаметр) 227,2 мм Caterpillar 6491851

The D-Ring Seal is a type of sealing element commonly used in hydraulic systems. Its cross-sectional shape resembles a capital letter “D,” with one flat side and one curved side. This design combines the sealing efficiency of an O-ring with added stability and resistance to twisting, especially in dynamic applications. The flat base allows the seal to sit securely in the groove without rolling or shifting during assembly or operation. This feature makes D-rings especially effective in reciprocating and rotating applications where O-rings may fail due to spiral twisting or extrusion. The D-Ring Seal provides a secure, leak-resistant seal between mating surfaces in hydraulic systems, with reduced risk of twisting or displacement.Attributes:• Suitable for static and dynamic sealing.• High pressure and fluid resistance.• Resistant to degradation from lubricants and temperature fluctuations.Applications: The D-Ring Seal is used in hydraulic motor housing to provide a secure, leak-resistant seal between mating surfaces and reliable fluid sealing under high pressure and vibration.
