China Industrial Automotive Rotary Shaft Hydraulic Cylinder Use Rubber Seal Rings

Description:

1: What is rubber seal rings
Rubber seal is a common form of a device for preventing leakage of fluid from one part of a container to another, whether dynamic or static. It is also called as rubber ring, rubber sealing, rubber seal ring. The catagories of rubber seals includes hydraulic seals(piston ring, rod ring, wipers, guide ring, buffer ring...), rotary seal(oil seal, coolant/water seal...), rubber o rings and so on. Care is needed in design, since poor tolerances can cause extrusion of the seal under pressure.
Material is also critical to performance, the following is the thermal Application of some materials:
Nitrile seal -30~+100celicus Degree
Viton Seal -20~+200 Celicus Degree
HNBR seal -30~+150celicus Degree
PTFE seal -250~+260 Celicus Degree
PMQ/VMQ -60~+250 Celicus Degree

2. Application Range

Rubber seals are used in a full range of equipment in the following industries:
• Automotive.
• Manufacturing.
• Off-highway.
• Oil refineries.

Material
It is very important to take into account the environment in which the rubber seal will operate when you are selecting the sealing element material. The most important factors are temperature, medium being sealed, pressure, and shaft speed.
