Low-Friction Premium Reinforced COMBI Seal for Heavy-Duty Rotary Shaft Service

Problem: Excessive lip load creates heat, wear and power loss, but weak contact allows dust and oil leakage.

Solution: Application-matched lip geometry and materials provide controlled contact, while the reinforced COMBI structure maintains dust and lubricant barriers.

Key Benefits

• Helps control friction and heat

• Maintains dust exclusion

• Supports stable high-duty rotation
