1500mm Rubber O Rings
Heat Resistant Seal Oring FKM Silicone NBR Rubber Factory Direct Sealing O Rings Silicone O-Ring
silicone o-ring for machinery car seals are one of the most common seals used in machine design,it can be used in static applications or in dynamic applications where there is relative motion between the parts and the O-ring.
Dynamic examples include rotating pump shafts and hydraulic cylinder pistons.
It has the advantages:
1. inexpensive;
2. Small installation space;
3. easy to make,easy to install;
4. stable performance;
Rubber O-shaped sealing ring is suitable for installation on various mechanical equipment, and it can seal under the specified temperature, pressure, and different liquid and gas media under static or moving state. Various types of sealing components are widely used in sanitary ware, ships, automobiles, hardware, electronics, toys, electrical appliances, aerospace equipment, machinery, and various instruments and meters. Rubber O-rings are mainly used for static sealing and reciprocating sealing. When used for rotary motion sealing, it is limited to low-speed rotary sealing devices. Rubber O-rings are generally installed in a groove with a rectangular cross-section on the outer circle or the inner circle for sealing. The rubber O-rings still play a good sealing and shock absorption effect in environments such as oil, acid, alkali, abrasion, and chemical erosion. Therefore, the rubber O-ring is the most widely used seal in hydraulic and pneumatic transmission systems.
