Dust-Proof Reinforced COMBI Rotary Shaft Seal to Stop Oil Leakage and Dirt Intrusion

Problem: Rotary shafts lose lubricant while external dirt enters the same sealing zone, accelerating wear on both sides.

Solution: A dedicated oil lip retains lubricant and an outward-facing dust lip blocks contamination, supported by a reinforced case.

Key Benefits

• Reduces oil leakage

• Blocks dirt intrusion

• Protects bearings and shaft surfaces
