COMBI Seal Premium Reinforced Dust-Proof Lubricant Retention to Reduce Grease and Oil Waste

Lubricant waste is often treated as a refill problem, but repeated grease or oil loss can point to damaged sealing lips, shaft wear, contamination, or poor fit. This premium reinforced COMBI seal is designed to protect the sealing zone from external dust while helping retain lubricant around bearings, hubs, axles, and gear drives. NBR or HNBR main sealing materials can be selected for the operating medium and temperature, while an optional PU dust-deflector lip adds abrasion-focused protection. The reinforced structure helps maintain fit under vibration and shock, reducing the conditions that lead to leakage and contaminated grease. Custom OEM and replacement sizes are available.

Description

Lubricant waste is often treated as a refill problem, but repeated grease or oil loss can point to damaged sealing lips, shaft wear, contamination, or poor fit. This premium reinforced COMBI seal is designed to protect the sealing zone from external dust while helping retain lubricant around bearings, hubs, axles, and gear drives.

Premium Reinforced Dust Contamination Proof COMBI Seal Minimize Lubricant Waste

Repeated grease or oil loss is expensive and can leave bearings under-lubricated. Better dust exclusion and stable sealing help protect both the lubricant and the component.
