The skeleton oil seal generally consists of three parts: an oil seal reinforcement skeleton and a self-tightening coil spring. NBR is one of the most commonly used rubbers for oil seals and O rings. Besides, food grade oil seal is currently the most used in the kitchen. In short, the lowest cost rubber seal. Also commonly used in oil seals are silicone fluoroplastics and PTFE.
The skeleton oil seal is mainly TC, but there are also many forms: SB SC TB and so on.
The material selected for the food grade oil seal lip part is PTFE, FDA food grade certification; greatly improved the wear resistance and fatigue resistance of PTFE. At the same time, the skeleton is made of 304/316 stainless steel with good corrosion.
The representative form of the oil seal is the TC oil seal, which is a rubber completely cover double-lip oil seal with a self-tightening spring. Generally speaking, the oil seal often refers to this TC skeleton oil seal. Besides, the TC profile is a shaft seal composing of a single metal cage with a rubber coating, a primary sealing lip with integrated spring and an additional anti-pollution sealing lip.
