Germany resogoo seals resogoo model resogoo price

resogoo seals are the customary term for general seals, simply referring to lubricating oil seals. They are mechanical components used to seal grease (oil is the most common liquid substance in transmission systems, and also refers to general liquid substances), isolating the parts requiring lubrication in the transmission from the output parts to prevent lubricating oil leakage. Seals used for static sealing and dynamic sealing (generally reciprocating motion) are called oil seals. The representative form of oil seals is the TC oil seal, which is a double-lip oil seal with a self-tightening spring fully covered by rubber. The term oil seal generally refers to this type of tc cased oil seal.

resogoo seal classification

Oil seals are generally divided into monolithic and assembled types. Assembled types allow free combination of the casing and lip material, and are generally used for special oil seals. Based on sealing function, characteristics, structural type, operating status, and sealing mechanism, oil seals can be categorized into various forms and names. However, conventionally, rotary shaft lip seals are called oil seals, while seals used for static and dynamic sealing (generally reciprocating motion) are called seals. The representative form of oil seals is the TC oil seal, which is a double-lip oil seal with a self-tightening spring fully covered by rubber. The term oil seal generally refers to this type of tc cased oil seal.

resogoo seal materials

Common materials for oil seals include: Nitrile rubber, Fluorocarbon rubber, Silicone rubber, Acrylate rubber, Polyurethane, Polytetrafluoroethylene, etc. 1) Nitrile rubber (NBR): It has good heat and wear resistance, resists various lubricating oils, greases, and oil-gas mixtures. Applicable temperature range: -30~120 degrees Celsius. However, it cannot be used in phosphate ester hydraulic oils or gear oils containing extreme pressure additives. It performs stably in gasoline and low aniline point mineral oils. 2) Polyacrylate rubber (ACM): Superior oil and heat resistance, wear resistance, ozone resistance, and UV radiation resistance. Especially resistant to lubricating oils, gear oils, motor oils, engine oils, and petroleum-based hydraulic oils containing extreme pressure agents. Suitable for working in the -30~150 degrees Celsius range. 3) Fluorocarbon rubber: Resistant to aging, heat, and oil. Suitable for almost all lubricating oils, fuel oils, and gasoline. It does not harden easily in oils containing extreme pressure additives. However, it has poor cold resistance and high-temperature wear resistance, and significant permanent compression set. Suitable for temperatures -20~250 degrees Celsius. 4) Silicone rubber: Outstanding high and low-temperature resistance. Can be used long-term at 150 degrees Celsius without performance change; can be used continuously at 200 for 10000h. Maintains its unique elasticity, ozone resistance, and weather resistance in the working temperature range of -70~260. 5) Polytetrafluoroethylene: Outstanding chemical stability, thermal stability, friction reduction, and self-lubrication. Its decomposition temperature is above 400. Therefore, it can work normally in the temperature range of -200~300 degrees Celsius. Except for free fluorine and alkali metals, it has excellent corrosion resistance to chemicals, solvents, hydroxides, and acids. Nitrile rubber and fluorocarbon rubber are widely used oil seal materials. The former is low-cost, but the latter offers significant improvements in temperature resistance and sealing, though at a higher cost. It still retains some negative commonalities of ordinary rubber materials, such as poor wear resistance, short service life, and high sensitivity to shaft eccentricity, making leakage relatively common. PTFE oil seals are high-tech products and represent the future direction of oil seal development [2]. When selecting oil seal materials, one must consider the material's compatibility with the working medium, adaptability to the working temperature range, and the lip's ability to follow the rotating shaft at high speeds. Generally, the lip temperature of an oil seal during operation is 20~50℃ higher than the working medium temperature, which should be noted when selecting materials. The working range of an oil seal depends on the material used: Nitrile rubber (NBR) is -40~120℃, Acrylic rubber (ACM) is -30~180℃, and Fluorocarbon rubber (FPM) is -25~300℃.

resogoo seal failure causes

Mechanical seal failures are generally identified only after phenomena such as abnormal leakage, abnormal wear, and abnormal torque occur. The causes of failure can be broadly categorized into four aspects: 1) Incorrect design and selection of the mechanical seal; 2) Poor quality of the mechanical seal; 3) The precision of the machine using or installing the mechanical seal does not meet requirements; 4) Incorrect machine operation.
