Chesterton SPLS Split Polymer Labyrinth Seal

The Chesterton SPLS Split Polymer Labyrinth Seal is a non-contact split rotary seal for splash lubricated bearing protection in large pumps, gearboxes, and other rotating equipment. It reduces installation time and outperforms conventional lip seals in operation. 

The SPLS design reduces the change of fretting and wear. It increases bearing and gearbox life by extending the mean time between equipment repairs. The polymer creates a non-contact three piece seal design that includes a rotor with an integrated valve, a stator, and a metal clamp with no wearing parts. While in operation, centrifugal force and gravity help ensure lubricant is contained within the labyrinth and flows back into the bearing housing while outside contaminants are excluded and redirected back to atmosphere.
