The combination of Dongguan Teflon cylinder O-ring and rigid PTFE sealing ring. The latter provides a low friction sealing surface, whether or not it is lubricated. The sealing ring can be an inner seal or an outer seal. The name of the seal produced by different seal manufacturers is different, and the shape of the PTFE seal is also different. Interestingly, although it has excellent sealing performance under moving conditions, the static friction is close to that of the Teflon cylinder O-ring. It is also worth noting that at very low pressures, the lip seal exhibits the lowest friction, and the relationship between the friction and pressure of a typical seal of a Teflon cylinder O-ring combination seal in a lubricated state, however in this In the case where the pressure is increased, the contact area of the lips is increased, and the friction is increased.
The advantages of the Teflon cylinder O-ring. The Teflon cylinder O-ring has the chemical resistance of PTFE and maintains the original flexibility and elasticity of the rubber seal. If the ratio of rubber to PTFE is high, it can work easily on both static and dynamic seals, and the contact area will increase, reducing the possibility of failure due to compression deformation. When used as a dynamic seal, Teflon also reduces friction due to the relationship of the sealing material, especially friction.
The combined hardness seal of the Teflon cylinder O-ring can also be used for specific applications. Dongguan Teflon cylinder O-ring wholesaler tells you that this seal consists of a hard seal cross section and a flexible cushion.China PTFE Teflon Hydraulic Seal Ring Encapsulated O-ring Oring Manufacturer. The hard section may be metallic or some other low friction material (such as polytetrafluoroethylene). It is essentially a compression-type seal and the elasticity is given by a cushion seal. A possible advantage of this seal is that it acts as a bearing and seal, accommodates lateral clearance, and provides an automatic "centering" effect.
