Introduction - type O sealing ring Dongguan DongSheng di sealing products co. , LTD

Type O sealing ring is a kind of cross section is circular rubber seals sealing ring, due to its cross section is type O, so called type O sealing ring, also called o-rings, began to appear in the middle of the 19th century, when use it as a steam engine cylinder sealing element. Common o-rings are: hole with YX o-rings, YX hole with block o-rings, shaft with YX type o-rings application is introduced: 1, the hole with YX type O sealing ring the purpose: used in hydraulic cylinder reciprocating motion of piston seal. Scope of application: TPU: general, general equipment hydraulic cylinder hydraulic cylinder. CPU: engineering machinery with hydraulic cylinder and the high temperature and high pressure oil cylinder. Material: polyurethane TPU, CPU, rubber. Products: hardness HS85 & plusmn; 2° A working temperature: TPU: - 40～+80℃，CPU：- 40 ~ + 120 ℃ with pressure: & le; 32 mpa working medium: hydraulic oil, the emulsion. Type 2, YX hole with a block type O sealing ring product use: is suitable for the cylinder pressure is greater than 16 mpa when used with YX type sealing ring, or cylinder eccentric bearing, seal protection role. Working temperature: - 40 ~ + 100 degrees of working medium: hydraulic oil, emulsion, water hardness of products: the HS 92 & plusmn; 5 a material quality: ptfe. 3, shaft with YX type O sealing ring product use: used for reciprocating motion in the hydraulic oil cylinder piston rod sealing applicable scope: TPU: general, general equipment hydraulic cylinder hydraulic cylinder. CPU: engineering machinery with hydraulic cylinder and the high temperature and high pressure oil cylinder. Material: polyurethane TPU, CPU, rubber seals product hardness: HS85 & plusmn; 2° A working temperature: TPU: - CPU: 40 ~ + 80℃ 40 ~ + 120 ℃ with pressure: & le; 32 mpa, working medium: hydraulic oil, the emulsion. Sealing condition is different, each device need advice according to the requirements of the own condition to choose the suitable type O sealing ring, if you have any question, welcome consulting seal, 17 years of experience in design research and development.
