DMHUI Environment friendly box combination oil seal
The box-type combination oil seal box type oil seal generally consists of a closed cavity formed by an outer ring and an inner ring, and is shaped like a box.
Construction: Cassette combination oil seal is generally composed of more than two sealing components. The sealed cavity has a plurality of auxiliary sealing lips. It extends the contaminants into the channel and forms a plurality of sealed spaces. The oil seal body can naturally separate the oil seals. , Called open combination oil seal. The oil seal body can not be divided naturally called a closed combination oil seal.
1. Strong sealing performance
Compared with the traditional TC and TB oil seals, this oil seal has a special design structure. When the axial run-out and radial swing motion, it has a strong sealing performance, a long period of pollutant intrusion, anti-pollution performance Extremely high, so that the oil seal can protect the chamber from contaminants in a complex moving working environment.
2. Extended maintenance cycle, low maintenance costs
The seal lip of the combined oil seal does not contact with the shaft surface, and the shaft surface needs no grinding during maintenance and replacement of the oil seal, which can greatly increase the service life of the shaft, extend the maintenance period, and reduce the maintenance cost.
3. High environmental performance
The cassette type oil seal is maintenance-free, and the lower number of replacements reduces the equipment downtime, reduces the leakage of the sealing medium to the soil and the water body, and reduces the potential pollution of the disassembled old parts to the surrounding environment. In today's greatly enhanced environmental awareness, we have more reason to choose environmentally friendly cartridge combination seals.
