Power-Process-Icon-Fluid-Sealing  Lip Seals – High Performance for Bearing / Gearbox Protection

​Chesterton offers a line of high-performance lip seals / radial shaft seals that are ideal for protection of bearings used in pumps, motors, gearboxes, and other rotary equipment. These seals keep operation lubricant in the housing while preventing penetration of external contaminants which would damage the bearings.

    Face Seal Options for High Reliability 

    ​Face seals are designed to positively seal out all sources unlike conventional lip seals and other bearing seal designs, contaminate ingestion by increasing bearing life and extending your equipment mean time between failure (MTBF). When operating conditions require positive sealing, the Chesterton GBS Face Seal is the seal to use.
