What are the similarities and differences between TG4 and TC? Do you know the performance of TG4 oil seal?

Aug. 18, 2022

TG4 oil seal is a general improved oil seal. Can replace TC, TB, VB, VC, SB, TC4, DKB and other oil seals. The interior adopts 3-lip design, which has good sealing performance. TG has a special corrugated outer diameter design. Particularly suitable for applications where the housing material has high thermal expansion, such as aluminum housings.
The material of TG4 oil seal is generally nitrile rubber and fluorine rubber.new
The standard skeleton oil seal of TG4 oil seal is a sealing element used to seal the oil of the rotating shaft in mechanical equipment. The cavity is basically static, so the TG4 oil seal is also called the lip seal of the rotating shaft. The common skeleton oil seal has two kinds of single lip and double lip. With the development of skeleton oil seals, double-lip skeleton oil seals have gradually replaced single-lip skeleton oil seals. During mechanical friction, some oil gets in when the machine is running. To prevent oil leakage from machine clearances, it is necessary to use oil sealing elements. Skeleton oil seal to prevent leakage and protect the environment.new
The sealing state of the skeleton oil seal: 1. The outer edge of the skeleton oil seal is statically sealed with the cavity, and the outer edge of the oil seal can be reliably positioned between the cavity. 2. The sealing state between the skeleton oil seal sealing lip and the shaft is a dynamic seal when the shaft is rotating, and a static seal when the shaft is stationary.
TG4 oil seal is a typical representative of skeleton oil seal. Generally speaking, the oil seal refers to the skeleton oil seal. The function of the skeleton oil seal is generally to isolate the parts that need to be lubricated in the transmission parts from the output parts, so as to avoid the leakage of lubricating oil. The skeleton is like the steel bars in a concrete member and acts as a steel bar that keeps the seal in shape and tension. The interior of the TG4 oil seal adopts a three-lip structure, and its sealing and dust resistance are better than those of the TC oil seal. Widely used in gasoline engine crankshafts, diesel engine crankshafts, gearboxes, differentials, shock absorbers, engines, axles and other parts.
