Type O sealing ring of tolerance

Type O sealing ring because the process is simple, convenient use, so using the scope of more extensive, but in different industry is different to the requirement of tolerance, so the general type O sealing ring how much is the tolerance of, tell you. Type O sealing ring size generally use outside diameter, inside diameter, wire diameter to express. General on the engineering drawing or just need to mark or when buying type O sealing ring inside diameter and the size of the wire diameter, outside diameter is equal to inner + 2 & times; Wire diameter, or only indicate the ratio of outer diameter to the size of the wire diameter. Type O sealing ring size tolerance is main mean diameter tolerance and wire diameter tolerance, the specification of tolerance mainly depends on the size of the size, the size, the greater the tolerance of the corresponding will also be larger. Such as the diameter of 0. 5 to 1. Standard for the 79 mm type O sealing ring of tolerance & plusmn; 0. 10 mm, wire diameter 0. 5 to 1. Standard for the 79 MM type O sealing ring of tolerance & plusmn; 0. 07MM。 From the above that, different size tolerance range is different, if the customer has no special requirements, general type O sealing ring manufacturer mainly B/T3672. 1 - 2002 M1 level of tolerance for production. Seal 17 years of professional manufacturer of sealing ring, has a modern standard workshop more than 20000 square meters, more than 30 professional technicians, have scientific CNC processing center, vulcanization molding equipment, professional custom high-precision seals for the customer, welcome to consult.
