Hits:Updated:2017-06-13 08:06:39【Print】

V-ring
Is an axial effect of the elastic rubber seal, used as a shaft without pressure seal. Seal lip has a better activity and adaptability, can compensate for greater tolerance and angular deviation, to prevent the internal grease or oil leakage, but also to prevent the outside of the splashing or dust intrusion.
O-ring
Mainly used for static sealing and reciprocating seal. For rotary motion seals, only for low speed rotary seals.
V-ring
Generally installed in the outer or inner circle on the rectangular cross-section of the seal from the role.
Y-ring
Widely used in reciprocating seal device. In addition, there are spring tension (spring storage) seals, PTFE sealing material is added to a spring, there are O-type spring, V-shaped spring, U-shaped spring.
Hole with YX type ring
Brief description Product use: for the reciprocating hydraulic cylinder piston seal. Scope: TPU: general hydraulic cylinder, general equipment hydraulic cylinder. CPU: hydraulic machine for construction machinery and high temperature and high pressure cylinder. Material: Polyurethane TPU, CPU, rubber Product hardness: HS852A Operating temperature: TPU: - 40 ~ +80 ℃ CPU: -40 ~ +120 ℃ Working pressure: 32Mpa Working medium: hydraulic oil, emulsion
YX hole with a ring
Brief description Product use: This standard applies to the cylinder working pressure greater than 16MPa when used with YX-type ring, or cylinder eccentric force, the role of the protection ring. Working temperature: -40 ~ +100 ℃ Working medium: hydraulic oil , Emulsion, aquatic product Hardness: HS 925A Material: Teflon
Shaft with YX type ring
Brief description Product use: for reciprocating hydraulic cylinder piston rod seal Scope: TPU: general hydraulic cylinder, general equipment hydraulic cylinder. CPU: hydraulic machine for construction machinery and high temperature and high pressure cylinder. Material: Polyurethane TPU, CPU, rubber Product hardness: HS852A Operating temperature: TPU: - 40 ~ +80 ℃ CPU: -40 ~ +120 ℃ Working pressure: 32Mpa Working medium: hydraulic oil, emulsion
Shaft with YX type ring
Brief description Product use: This standard applies to the cylinder working pressure greater than 16MPa when used with YX-type ring, or cylinder eccentric force, the role of the protection ring. Working temperature: -40 ~ +100 ℃ Working medium: hydraulic oil , Emulsion, aquatic product Hardness: HS 925A Material: Polytetrafluoroethylene According to: Enterprise standard
O type rubber seal ring
(GB1235-76) Brief description Product use: This standard O-type rubber seals for hydraulic pneumatic systems and a variety of mechanical equipment and components, in the specified pressure, temperature and different liquid and gas medium, at rest or Motion state from the sealing effect. Working temperature: -40 ~ +230 ℃ Working pressure: <10 ~ 220Kg, f / cm Working medium: air, water, oil Product hardness: 40 ~ 852A Material: nitrile rubber, silicone, fluorine rubber, ethylene propylene rubber
O-ring with retaining ring
Brief description Product use: This standard applies to the cylinder pressure greater than 10MPa when used with O-ring. Working temperature: -100 ~ 200 ℃ Working medium: hydraulic oil, emulsion, water Material: Teflon According to: JB / ZQ4224-86 Adaptation to GB1235-76
J type without skeleton dust ring
Brief description Product use: for reciprocating cylinder, cylinder piston rod or stem exposed from the dust effect. Scope: TPU: engineering machinery, general machinery, cylinders, such as various types of valves. CPU: engineering machinery cylinder, poor working conditions of the oil cylinder. Material: Polyurethane, nitrile rubber Working temperature: -40 ~ 120 ℃ Product hardness: HS 805A According to: JB / T6657-1993 ※ Seal ring sealing performance, high working life, dynamic pressure Seal working life than conventional rubber sealing products 510 Times, up to several times, under certain conditions with the sealed matrix with the same life. ※ sealing ring friction resistance is small, dynamic and static friction force equal, is 0-shaped rubber ring friction 1/2/4, can eliminate low-speed, low-pressure movement crawling phenomenon. ※ high wear ring sealing, sealing surface wear with automatic elastic compensation. ※ Seal ring good self-lubricating performance. Can be used for oil-free seal. ※ seal structure is simple, easy to install. ※ Sealing ring working pressure: 0 a 300MPa; Working speed: 15m / s; Operating temperature: -55250 ℃. ※ seal for media: hydraulic oil, gas, water, mud, crude oil, emulsion, water - ethylene glycol, acid, alkali, chemicals and so on.
