Description
Stop packed sand and wet mud from migrating along rotating shafts. The reinforced COMBI structure creates staged barriers that protect lubricant and bearings in harsh service.

Reinforced COMBI Seal with Premium Dust-Proof Design to Prevent Sand and Mud Ingress

Problem: Sand and wet mud collect around rotating shafts, then work inward and contaminate the bearing cavity.

Solution: A reinforced shell and staged dust-lip geometry intercept packed debris before it reaches the main oil-retaining lip.

Key Benefits

  • Resists sand, mud and splash intrusion

  • Protects grease and oil cleanliness

  • Reduces shaft scoring and bearing damage
