Conventional labyrinth-type oil blocking rings for rotating equipment suffer from poor sealing performance, frequently resulting in oil seepage and leakage. These issues severely compromise the safe operation of the equipment, hinder safe and orderly production, and may even cause a fire. Through years of research, our company has developed the return-type oil blocking. This product consists of a rotating ring and a stationary ring, featuring a simple structure and excellent sealing performance.

Product Features

The return-type oil blocking consists of a rotating ring and a stationary ring, featuring a simple structure that facilitates easy installation and maintenance.

The rotating ring of the return-type oil blocking rotates with the shaft and is designed with multi-start threads on its outer diameter. In cooperation with the stationary ring, these threads enable the oil to be flung back into the bearing housing by the rotation of the rotating ring, thereby preventing oil leakage.

The rotating ring of the return-type oil blocking is precision-machined and does not affect the original dynamic balance of the shaft.

Application Range

Shaft end seals for various types of rotating equipment.
