Rubber sealing ring is a popular type of sealing ring in the market. But many customers do not have a true understanding of rubber sealing rings, so people often come to our factory to ask how the weight of rubber sealing rings is calculated?

The weight calculation formula for rubber sealing rings:

The weight calculation formula for rubber sealing rings is (square of cross-sectional radius * 3.14) * (the diameter of the rubber sealing ring multiplied by 3.14+line diameter) * the density of the rubber sealing ring/1000. The unit weight is grams.

The outer diameter of the rubber sealing ring is 50mm, the wire diameter is 4mm, and the material is NBR rubber. The weight calculation formula for the rubber sealing ring is as follows:

The density of 2 * 2 * 3.14 * (46 * 3.14+4) * 1.2NBR rubber/1000=2.2373 grams. The weight of rubber sealing rings is directly related to the material density of rubber sealing rings. The density of different materials varies. Common rubber sealing ring materials include NBR, EPDM, silicone, fluororubber, PU, and so on.
