Centrifugal Protection & Bearing Longevity
The primary function of this NBR Rubber RB Type Gamma Seal is to act as a primary barrier against external contaminants, significantly extending bearing life.
As the seal rotates with the shaft, the metal casing utilizes centrifugal force to create a dynamic slinger effect, aggressively repelling mud, water, and coarse grit.
While the axial rubber lip maintains a slight, low-friction contact against the stationary surface to prevent grease leakage, the centrifugal action effectively keeps contaminants away from the primary internal sealing lip or bearing.
In many configurations, this gamma seal o ring design ensures that even during high-pressure cycles, the lubricating integrity is preserved in challenging environmental conditions.
