​​​​​​​​​​​​​​​​​​​​​​​​​​Chesterton's General Bearing Seal includes positive-contacting face seals that minimize atmospheric contaminants from migrating into the housing area.
The use of simple lip seals in process pump applications typically creates a vicious cycle of unnecessary downtime as lip seals groove the shaft, progressively losing their compressive seal as well as damaging the shaft.  Chesterton's General Bearing Seal (GBS) eliminates grooving on the shaft, improves MTBM, and increases the overall reliability of the gearbox.​
