Filled Kalsi Seal Sizes
Filled Kalsi Seals were developed to retain lubricant in lower pressure, higher speed non-abrasive applications. The C-shaped construction of the shell allows the use of a low modulus silicone energizer that minimizes contact pressure at the seal-to-shaft interface. As with other Kalsi-brand rotary shaft seals, the Filled Kalsi Seal incorporates hydrodynamic waves that cause the seal to hydroplane on a film of lubricant when rotation occurs. This combination of features reduces running torque and seal-generated heat significantly, compared to single material Kalsi Seals.
