Diameter of 1.78 import O-ring, usually applied to the groove depth is 1.30, the groove width within 2.30. This is Taiwan's top Wall Sealing Technology Co., Ltd - O-ring manufacturer's recommended parameters, of course, only as a reference, and is in the static case, when in dynamic, as well as contact with the liquid, the gas, we need other sizes, Specifically, I will examine to answer your questions. When the diameter is 1.78 to a liquid as a medium that if you choose slot sizes? Our proposal groove depth is 1.50, width 2.30, the shaft chamfer was 1.1. Then a gas as a medium, it is recommended groove depth of 1.55, width 2.30, the shaft chamfer was 1.1. Carrying O-ring When grooving, chamfering shaft why? Because avoid reciprocation O-rings, at work, appears bite phenomenon. O-ring is a circular cross-section of the rubber ring, because of its cross-section O-type, it is called the O-ring. Hydraulic and pneumatic drive system is the most widely used one. Usually in the Taiwan enterprises, Japanese companies called the O-Ring. Non-metal O-ring seal, long life, compact structure, disassembly is also convenient. Different types of fixed seal or dynamic seal applications, O-ring seal element provides designers with an effective and economical. O-ring seal element is a two-way effect. The initial terms of radial or axial compression, giving O-ring seal its initial capacity. Sealing force generated by the system pressure and initial sealing force Synthesis total sealing force, with which to improve the system pressure increases. O-ring seal in the static case, display a prominent role. However, where appropriate in a dynamic, O-rings are often used, but it is limited by the speed of the seals and pressure. Often I hear people say, Which O-ring manufacturers of O-ring is better? In fact, this is a benevolent see benevolence and the wise see wisdom of the problem. We know that O-rings are standard, most of the O-ring is made of a synthetic rubber material. Good O-ring is not good, in the final analysis depends on whether suitable for your use, also is to see whether the high cost O-rings. If you are O-ring product quality is not very high, you can consider choosing domestic O-ring, generally with a number of relatively low domestic prices. If you are O-ring product quality requirements are relatively high, you can consider choosing import O-ring, general import O-ring O-ring up domestic prices will be relatively high. In this case, it suggested the use of Taiwan's top Wall seal, the company has a complete and scientific quality management system and strong technical force, the O-ring seals and other cost-effective products. Taiwan Walter tip seal product line O-ring, star-ring, ED ring / pipe joints seals, rubber balls, washers, seal, pneumatic seal, polyurethane seal, rubber ring, rubber flat washer and miscellaneous pieces of rubber. Import O-ring rubber used: NBR NBR German raw rubber, fluorine rubber FKM / VITON for American raw rubber, silicone SI / SIL Japanese raw rubber, EPDM rubber EPDM Germany raw rubber and so on, OTP factory produced products, raw materials imported 100% guaranteed convenient, it also gives the quality of imported seals provide a guarantee temperatures. OTP brands imported seal American Standard successful Japanese standard size model specifications complete, the company of different sizes stock has broken through the 10,000 kinds of products, more than the total number of mold reached 5000, in the same industry is the largest manufacturer of imported seals One.
