T- NR29/S turbocharger sealing bush description:

The sealing device is divided into three types according to the structure: contact type, piston ring type and labyrinth type. Piston ring seals are commonly used in small boosters as an oil seal. There are many types of labyrinth seals, axial and radial labyrinth seal for the turbocharger used as a gas seal. The smaller the gap between the gas seal sheets, the better the sealing effect. When a pressurized air is introduced from the compressor end to the gas seal, the sealing effect is enhanced.
