Advantages import NBR rubber o-ring: performance, import NBR rubber o-ring working life high dynamic pressure seal 5-10 times working life than conventional rubber seal products, up to a few times, under certain conditions can seal matrix with life. O-ring friction is small, dynamic and static friction is equal, "0" shaped rubber ring friction of 1 / 2-1 / 4, can be eliminated at low speed, low pressure movement "crawling" phenomenon. NBR rubber o-rings imported high wear resistance, sealing surface wear and tear with automatic elastic compensation. O-ring good self-lubricating properties. Can be used for oil-free seal. O-ring structure is simple, easy to install. O-ring Working pressure: 0-300MPa; Working speed: ≤15m / s; Working temperature: -55-250 degrees. O-ring Applicable medium: hydraulic oil, gas, water, mud, oil, emulsion, water - glycol acid. Scope import NBR rubber o-ring: O-ring is suitable for installation in various machinery and equipment, at a specified temperature, pressure, and various liquid and gaseous media, at rest or in motion from the seal. On the machine, marine, automotive, aerospace equipment, metallurgical machinery, chemical machinery, engineering machinery, construction machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery, and a variety of instruments, a large number of applications for various types of seals elements. O-ring is mainly used for static seals and reciprocating seals. For rotational movement of the seal when limited to low-speed rotary sealing device. O-ring is usually installed on the outer or inner circle from the seal section is rectangular trench. Imported NBR rubber o-ring seal still play a good shock absorption in oil, acid, wear, erosion and other environmental chemistry. Therefore, O-ring hydraulic and pneumatic drive system most widely used a seal. About O-ring: NBR rubber o-ring import is a circular cross-section rubber seal ring is mainly used for mechanical parts to prevent leakage of liquid and gaseous media under static conditions O-ring in certain circumstances... can also be used as dynamic sealing element axially reciprocating and slow rotary motion. Depending on the conditions, different materials can be selected corresponding. to try to use the O-ring when a large section of the O-ring is usually used in Under the same circumstances gap volume imports NBR rubber o-ring to be squeezed into the gap should be less than it is to squeeze the maximum allowable value.
